1.              Explain why continual quality improvement is important.
Ans.  The basis for constant change is that it is important so as to contend in the worldwide commercial center. Simply keeping up business as usual, regardless of the fact that existing conditions is high caliber, resemble stopping in a race. Since customers' needs are steadily changing constant quality change is basic. Late thing improvements quickly get the opportunity to be standard and affiliations must stay centered in the overall business focus by meeting customers developing needs.

2.              What is management’s role in continual quality improvement?
Ans.    Administration can assume the vital initiative part and that basically is its part in nonstop change by doing the accompanying:
·         Building up an association wide quality chamber and serving on it.
·         Working with the quality committee to build up particular quality change objectives with timetables and deadlines.
·         Providing the important good and physical backing. Moral bolster shows itself as responsibility. Physical bolster comes as the assets expected to perform the quality change destinations.
·         Planning occasional advancement surveys and giving acknowledgment where it is merited.
·         Incorporating persistent quality change with the customary prize framework, including advancements and boosts in salary.

3.              Discuss the Kaizen approach
Ans.    Kaizen is the name given by the Japanese to the concept of continual incremental improvement. Kai means, “change” and Zen means “good.” Kaizen, therefore, means making changes for the better on a continual, never-ending basis. The improvement aspect of Kaizen refers to people, processes, and products.
If the Kaizen philosophy is in place, all aspects of an organization should be improving all the time. People, processes, management practices, and products should improve continually: “good enough” is never good enough.

Ø  Kaizen value system.
The underlying value system of Kaizen can be summarized as continual improvement of all things, at all levels, all the time, forever. All of the strategies for achieving this fall under the Kaizen umbrella. Executive managers, middle managers, supervisors, and line employees all play key roles in implementing Kaizen.

Ø  Role of executive management
 Executive managers are responsible for establishing Kaizen as the overriding corporate strategy and      communicating this commitment to all levels of the organization; allocating the resources necessary for Kaizen to work; establishing appropriate policies; ensuring full deployment of Kaizen policies; and establishing systems, procedures, and structures that promote Kaizen.

Ø  Role of middle managers.
Middle managers are responsible for implementing the Kaizen policies established by executive management; establishing, maintaining, and improving work standards; ensuring that employees receive the training necessary to understand and implement Kaizen; and ensuring that employees learn how to use all applicable problem- solving tools.

Ø  Role of supervisors.
Supervisors are responsible for applying the Kaizen approach in their functional roles, developing plans for carrying out the Kaizen approach at the functional level, improving communication in the workplace, maintaining morale, providing coaching for teamwork activities, soliciting Kaizen suggestions from employees, and making Kaizen suggestions.

Ø  Role of employees.
Employees are responsible for participating in Kaizen by taking part in teamwork activities, making Kaizen suggestions, engaging in continual self-improvement activities, continually enhancing job skills through education and training, and continually broadening job skills through cross- functional training.

Ø  Kaizen and quality.
In a total quality setting, quality is defined by customers. Regardless of how customers define quality, it can always be improved and it should be, continually. Kaizen is a broad concept that promotes quality from the all-encompassing Big Q perspective

4.              How would you describe a lean system?
Ans.   Lean is a TQM approach originally designed for manufacturing, but since adapted to any kind of organization. It is intended for smoother, more flexible process flow, reducing waste, and improving the organization’s competitive posture. A lean framework is unified with a business change strategy that delivers better items or administrations with less assets. A lean framework concentrates on diminishing and taking out the accompanying sorts of waste.

Ø  Overproduction waste- this incorporates making to a greater extent an item than is required

Ø  Stock waste- stock waste is conveying alludes to conveying a greater amount of a stock than is required at a given time

Ø  Movement waste- this is the superfluous development of a creation methodology or conveyance of an administration

Ø  Transportation waste- exorbitant development of parts in the assembling procedure is considered transportation waste

Ø  Over processing waste- running past client prerequisites with no identifiable included quality is waste

Ø  Deformities waste- rejected work or revamp from a procedure or generation run is imperfections waste

Ø  Holding up waste- individuals or machines sitting unmoving in light of the fact that the procedure is not prepared for info is waste

Ø  Underutilization waste- the under use of gifts, aptitudes, individuals and innovation is inefficient when assets are not being completely misused.

5.              What is lean six-sigma and how would you apply it to a quality management system?
Ans.  Kaizen is the name given by the Japanese to the concept of continual incremental improvement. Kai means “change” and zen means “good.” Kaizen, therefore, means making changes for the better on a continual, never-ending basis. The improvement aspect of Kaizen refers to people, processes, and products.



 





The Five-Step Plan is the Japanese approach to implementing:

Ø  Step 1: Straighten up. This step involves separating the necessary from the unnecessary and getting rid of the unnecessary in such areas as tools, work in process, machinery, products, papers, and documents.
Ø  Step 2: Put things in order. This step involves putting such things as tools and material in their proper place and keeping things in order so that employees can always find what they need to do the job without wasting time looking.
Ø  Step 3: Clean up. This step involves keeping the workplace clean so that work can proceed in an efficient manner, free of the problems that can result when the work site is messy.
Ø  Step 4: Standardize. This step was originally aimed at standardizing how the first three of the Five-S’s were implemented and maintained, but since then expanded to include standardizing on best practices. Visual management is also a major component of standardization.
Ø  Step 5: Discipline. This step involves careful adherence to standardized work procedures. This requires discipline.

6.              Define benchmarking Ans.
Ans.   Benchmarking is a procedure for contrasting an association's operations or procedures and those of a best-in class entertainer. The target of benchmarking is real execution change accomplished rapidly. Benchmarking spotlights on procedures and practices, not items. Benchmarking is done between consenting associations. Benchmarking accomplices are every now and again from diverse businesses. Benchmarking is a part of aggregate quality. Benchmarking must be drawn nearer in a sorted out, arranged way, with the regard and investment of top administration. Benchmarking groups must incorporate the individuals who work the procedures. Benchmarking is not limited inside of industry limits, but rather just to best-in-class forms.


7.              How can you apply benchmarking data?
Ans.   Benchmarking data first should be assembled and inspected to center fissure between the under entertainer and the best in class. The accumulated data can be used as a piece of game plans that will help close the fissure. A pilot model can be used to apply the amassed benchmarked data with get ready for directors, suppliers or customers. With preparation and setting up the benchmarked data can be used to execute another method. With the new process set up beginning issues can be worked out to help close the opening. As the methodology is situated up and issues are being worked out progression should be watched and benchmarks should be redesigned to end up best in class.

8.              What is a JIT system?
Ans.  JIT/Lean is an administration logic that looks to take out all types of waste. As a creation framework, JIT/Lean delivers just what is required, when it is required, in the amount required. Taiichi Ohno is credited with the improvement of the Toyota Production System and JIT/Lean. The root support for JIT/Lean is enhanced item quality with lower expenses. JIT/Lean started as a method for lessening the seven squanders. After some time, the JIT/Lean framework came to be a force framework whose little parcel generation is upheld by lessened setup times. All out profitable upkeep and measurable procedure control were coordinated to give the important generation unwavering quality and consistency. Persistent change gives the vehicle to the persevering assault on all squanders.

9.              What are the benefits of JIT/lean?
Ans.   A discussion of the benefits of JIT/Lean must include four very important topics: inventory and work-in-process, cycle time, continual improvement, and elimination of waste. The discussion could be expanded to include such topics as reduced time-to-market, improved employee work life, flexibility, and employee ownership. All of these are definite benefits of JIT/Lean, but this discussion will be confined to the critical four mentioned. These are the usual targets of a JIT/Lean implementation.

Inventory and Work-in-Process
Just-in-time/Lean attempts to drive inventory to zero. But remember that this is a philosophical objective—an aiming point, if you will. In reality, zero inventory makes no sense. Without some inventory, you have nothing from which to produce your goods. The real objective is to minimize the inventory to the maximum possible extent without shutting down production. It is also important to recognize that there are at least three kinds of inventory. First, there is the inventory of raw materials and parts needed to make the product. Traditionally, these have filled warehouses, with enough on hand for several weeks of production, or longer. Second, there is the work-in-process (WIP) inventory of semi-finished goods. WIP includes all materials and parts that have been put into the production system, including the various stages from the first process to the last within the factory.

Cycle Time
Production cycle time is defined as the period bounded by the time materials are sent to the manufacturing floor for the making of a product and the time the finished goods are dispatched from the manufacturing floor to a customer or to finished goods storage. Generally speaking, the shorter the production cycle time, the lower the production cost. That may be reason enough to pay attention to cycle time, but there are other benefits. Short cycles improve a factory’s ability to respond quickly to changing customer demands. The less time a product spends in the production cycle, the less chance there is for damage.

Continual Improvement
You should have a good understanding of continual improvement as applied in a total quality context. Continual improvement seeks to eliminate waste in all forms, improve quality of products and services, and improve customer responsiveness— and do all of this while at the same time reducing costs. A note of caution should be added in regard to interpretation of what constitutes improvement: Problem solving is not necessarily improvement. If a process that had previously been capable of producing 95 out of 100 good parts deteriorates to a level of 50 good parts and the problem is found and corrected to bring the process back to where it had been—that is maintenance not improvement. Maintenance is restoring a capability that previously existed. On the other hand, if a process was capable of 95 good parts out of 100 produced and a team developed a way to change the process to produce 99 good parts—that would be improvement.


10.          Discuss automation system ideas for JIT/lean.
Ans.   Automation may be advantageous in many applications, but if you have not solved the problems in the human- operated versions of those same applications, you are not ready to automate them effectively. If you try, you will auto- mate your problems and will find the robots far less adept at working around them than the humans they replaced.
It is frequently found that the need for automation is decreased or eliminated by converting to JIT/Lean. We certainly found that to be the case in two electronics plants. We were well into a program to build a factory of the future. The building was ready, much of the automation was on hand, and the rest—several million dollars’ worth—was on order when we started the conversion to JIT/Lean. Within months, it had become obvious to everyone, including the designers of the new factory, that we were getting more out of JIT/ Lean for almost no investment than could be projected for the new automated plant. The outstanding orders for automation equipment were cancelled and penalties were paid, and we walked away from the whole idea. We had learned in those few weeks of exposure to JIT/Lean that world- class manufacturing equates to JIT/Lean in a total quality environment, not to a factory full of robots and automatic guided vehicles. JIT/Lean and automation are compatible, but one should look long and hard at the need, and the company’s readiness for it, before automating processes.
Having said that, automation clearly has its place in harmony with JIT/Lean. There are many examples of very successful automated plants, especially for high-volume manufacturing. Automation and JIT/Lean are completely compatible. Probably the best example of that is in today’s auto industry. Two such plants have recently come on-line in Alabama and Georgia. Hyundai opened its first American plant in Montgomery, Alabama, in May 2005, making 300,000 vehicles per year there. The Alabama-produced Sonata sedan has been ranked in the top three in J. D. Power and Associates’ mid-size sedan category in 2008, 2009, and 2010.

Article1: What I Gained from Choosing the Rocky Road.
Now this is an article I can relate to. I have consistently stretched my capabilities by going through situations which I was very unprepared for. In other words comma I have quite often taken the rocky road. It's a brilliant piece of advice. A few years ago I would have never imagined that I would be able to edit films and videos. And today I'm putting it on my resume as one of my skills. This is only because I took a leap at the chance in doing things that were not so easily in front of me.
Taking risks in life has forced me to adapt and learn new things. It has been said that no experience goes to waste. And this is no doubt true. I'll send some may feel down on themselves if they feel their circumstances are less than what they would consider appropriate or successful. But comma keeping in mind that no experience go to waste, one may view one's current circumstances through a different perspective.
For example, interning at a company, where responsibilities may include filing papers and answering the phone is a very valuable experience, particularly if you have never worked in an office before. This experience now makes you richer and more valuable As you move forward into your future.
Even jobs that may seem menial at times have great benefits. If we take a person's life to be total quality case comma then it's about continual Improvement of one's characteristics and circumstances. In order to improve comma one must be aware of areas that require or can be improved upon. Without stretching oneself and moving into new and possibly uncomfortable situations, one is not tested. Having never worked in an office before, one could not be counted upon to know how to file papers and answer phones. Which, if one desires to move up in the corporate world, they must have a Mastery of.

Article2: Before I Became a Stylist, I Sold Shoes at the Mall. Here's What I Learned
I concur with Kim with regards to discussing continually working with a grin all over and an inspirational state of mind. This is even more genuine when working in a retail domain. Despite the fact that this is critical the two things that stood out most to me in this article were identified with being monetarily autonomous and privilege. I have dependably felt as if I needed to be monetarily autonomous. I for one never enjoyed depending on others to purchase me things that I needed to acquire myself. This ties over into what Rachel Zoe expressed about privilege. Certain regions of New Jersey are extremely affluential and when families that live in these regions give their children everything that they need growing up they never take in the estimation of a dollar. By having an occupation as a youngster, particularly a lowest pay permitted by law work, one really figured out how hard it can be to simply have a couple of additional dollars in their pocket to spend at their relaxation. Without this experience numerous youthful grown-ups have a troublesome time managing their own funds. Again this can tie into expert professions as individuals will be more shrewd about budgetary choices for organizations on the off chance that they have this involvement in their childhood.

Article3: Dream Big But Be Humble: Lessons That Led Me from the Factory Floor to the Executive Floor
Working in this present reality is a mix of book learning, road information, and now and again "tribal" learning. Applying that book learning instantly does not compare to the right choice. The world is not obvious. There are numerous more variables that new graduates essentially won't consider, or even know not of. Like Blace said, there ought to be something to extension this hole or help with transitioning understudies to working representatives. Numerous universities have coop and entry level positions which are great. Yet, I additionally feel that school classes ought to be reasonable more than essentially book learning. I concur with Ralph from the article that being unassuming, taking your prescription and proceeding onward is the most ideal approach to learn. Concede you are new, discover a coach, and retain however much as could reasonably be expected from those individuals. Despite the fact that we switch jobs,whether an alternate position or organization, there are numerous life lessons we learn along that way that can be connected to anyplace we go.

     Q 1. Discuss the eight principles of the ISO 9000 standard
Ans. Ans. The Eight Principles of the ISO 9000 standards from the Total Quality Management are as follows:

1.  Customer Focus:- Customer focus means to understand the needs of the customers and to fulfill that needs, and strive to exceed customer requirements.
2.   Leadership:- Leadership means establishing unity of purpose and organizational direction  and provide an environment that promotes employees involvement and achievement of objective.
3.  Involvement of People:- Involvement of people means taking advantage of fully involved employees and using all their abilities for the benefit of the organization.
4.  Process Approach:-  Recognize that things accomplished are the results of processes and that processes along with related activities and resources must be managed.
5.  System Approach to Management:- The multiple interrelated processes that contribute to the organization’s effectiveness are a system and should be managed as a system.
6.  Continual Improvement:-Continual improvement should be a permanent objective applied to the organization and to its people, processes, systems, and products.
7.   Factual Approach to Decision Making:- Decisions must be based on the analysis of accurate, relevant, and reliable data and information.
8.  Mutually Beneficial Supplier Relationships:- The organization and the supplier both get benefited from one another’s resources and knowledge which is valuable to both of them.

Q 2. Discuss Pareto Charts
  



The Pareto chart is a very useful tool wherever one needs to separate the important from the trivial. The chart, first promoted by Dr. Joseph Juran, is named after Italian economist and sociologist Vilfredo Pareto (1848–1923). He had the insight to recognize that in the real world a minority of causes led to the majority of problems. This is known as the Pareto Principle.
The Pareto chart in figure above labels a company’s customers A, B, C, D, E, and all others. The bars represent the percentages of the company’s sales going to the respective customers. Seventy-five percent of this company’s sales are the result of just two customers. If one adds customer C, 90% of its sales are accounted for. All the other customers together account for only 10% of the company’s sales. Bear in mind that “all others” may include a very large number of small customers. Which customers are the ones who should be kept happy? Obviously, A, B, and perhaps C are the most critical. This would suggest that customers A, B, and C are the company’s core market and all the other customers represent a marginal business. Decisions on where to allocate resources should be made accordingly.

The Pareto chart in Figure above shows bars representing the sales of a particular model of automobile by age group of the buyers. The curve represents the cumulative percent- age of sales and is keyed to the y-axis scale on the right. The manufacturer has limited resources in its advertising budget, and the chart reveals, which age groups are the most logical choice to target. Concentrating on the 26 to 45 age bracket will result in the best return on investment because 76% of the Swift V-12 buyers come from the combination of the 36 to 45 and 26 to 35 age groups. The significant few referred to in the Pareto Principle are in the 26 to 45 age group. 





Q 3. Discuss fishbone diagrams.

Fishbone diagrams (also called Ishikawa diagrams) are causal diagrams created by Kaoru Ishikawa (1968) that show the causes of a specific event. Common uses of the Ishikawa diagram are product design and quality defect prevention, to identify potential factors causing an overall effect. Each cause or reason for imperfection is a source of variation. Causes are usually grouped into major categories to identify these sources of variation. The categories typically include

·         People: Anyone involved with the process
·       Methods: How the process is performed and the specific requirements for doing it, such as policies, procedures, rules, regulations and laws
·         Machines: Any equipment, computers, tools, etc. required to accomplish the job
·         Materials: Raw materials, parts, pens, paper, etc. used to produce the final product
·         Measurements: Data generated from the process that are used to evaluate its quality
·         Environment: The conditions, such as location, time, temperature, and culture in which the process operates




Q 4. Discuss histograms.

Ans. Histograms have to do with variability. Two kinds of data are commonly associated with processes: attributes data and variables data. An attribute is something that the output product of the process either has or does not have.  Variables data are data that result when something is measured. A histogram is a measurement scale across one axis and a frequency of like measurements on the other.




Q 5. Discuss control charts for variables

Shewhart developed the control chart to separate the special causes from the common causes. Data are plotted over time, just as with a run chart; the difference is that the data stay between the upper control limit (UCL) and the lower control limit (LCL) while varying about the centerline or average only so long as the variation is the result of common causes (i.e., statistical variation). Whenever a special cause impacts the process, one of two things will happen: Either a plot point will penetrate UCL or LCL, or there will be a “run” of several points in a row above or below the average line. Control charts are the appropriate tool to monitor processes. The properly used control chart will immediately alert the operator to any change in the process. The appropriate response to that alert is to stop the process at once, preventing the production of defective product.




Q 6. Discuss flowcharts and give a simple example

Ans. Flowcharts are used in a total quality setting for charting the inputs, steps, functions, and outflows of a process to understand more fully how the function works and who or what has input into and influence on the process, its inputs and outputs, and even its timing. The survey is used to obtain relevant information from sources that otherwise would not be heard from in the context of providing helpful data.




Q 7. Explain what is an FMEA.

Ans. A flowchart is a graphic representation of a process. A necessary step in improving a process is to flowchart it. In this way, all parties involved can begin with the same understanding of the process. It may be revealing to start the flowcharting process by asking several different team members who know the process to flowchart it independently. If their charts are not the same, one significant problem is revealed at the outset; there is not a common understanding of the way the process works. Another strategy is to ask team members to chart how the process actually works and then chart how they think it should work. Comparing the two versions can be an effective way to identify causes of problems and to suggest improvement possibilities. The most commonly used flowcharting method is to have the team, which is made up of the people who work within the process and those who provide input to or take output from the process, develop the chart. It is important to note that to be effective, the completed flowchart must accurately reflect the way the process actually works, not how it should work. After a process has been flowcharted, it can be studied to determine what aspects of it are problematic and where improvements

Q 8. Provide an overview of the Toyota practical problem solving process.

Ans. Overview of Toyota practical problem solving process: Toyota’s “Practical Problem-Solving Process” is said to have seven main steps, although the number of steps may depend on one’s definition of “step.” Note that Step 2, for example, is broken into several sub-processes. Regardless of how the process steps are counted, the excellent Toyota process is appropriate for almost all situations, including both latent and existent problem categories

Step 1: Perceive the initial problem
Step 2: Clarify the problem
Step 3: Determine the point of cause
Step 4: Determine the Root cause using the Five-Why Analysis
Step 5: Develop and Implement a countermeasure
Step 6: Determine the Effectiveness of the countermeasure
Step 7: Change the Standard

Q 9. Explain a total quality decision making process.

Ans. The decision-making process is a logically sequenced series of activities through which decisions are made.






1) Identify or anticipate the situation:
a. Identify the problem or look for opportunities which can be worthwhile
b. Identify whether it will make difference
c. How much important it is to solve the problem

2) Gather the facts:
a. What is relevant and what is not relevant to the decision?
b. What do you need to know before you can make a decision

3) Consider Alternatives:
a. List all of the various alternatives available
b. Evaluate each alternative in light of the facts

4) Choose the Best Alternative, Implement, Monitor, and Adjust:
a. Select the best alternative and implement it.
b. After implementing, monitor the progress.
c. Adjust the requirements accordingly.

Q 10. Explain why quality tools are important

Ans. Importance of quality tools : Quality management includes planning, processes, and acceptable, organized outcomes. Quality management tools and some useful steps to follow are:

 Project Planning – Here you should create a project checklist as well as a project control process. Team members can use this planning phase to identify possible conflicts, changes, or risks associated with the project and, at this stage, should write the project scope.

·       Pareto Charts – A Pareto chart is an easy way to identify tasks within the project and prioritize their importance. The final goal of the Pareto chart is to determine where to maximize efforts to obtain maximum results.

·       Fishbone Charts – The fishbone chart identifies faults or problems in the process or project. It is often used as a graphic demonstration to identify problems, their causes and effect.

·         Histogram – This bar chart includes project variables and identifies root problems. It can also provide a glimpse of where problems lie in relation to the entire project, or on how large scale they appear.

          Charts and Graphs – Visual components are often the best way to understand your quality management process to see how well it functions initially and throughout the project, and to evaluate project outcomes.

Article1: What Designing a Shampoo Bottle Taught Me About Business

This article brought some interesting things to light. The obvious being how big should a shampoo bottle hole be?  When I first started reading the article I went right into my engineering mind and thought well why not make a bunch of different sized holes and test how much shampoo comes out. The size that provides enough to cover the average persons head is the right size.  As I read on I found out this is not the correct answer. The correct answer is whatever most consumers would like the best.  It could be that the consumers feel the mathematical minimum needed to wash your head is not enough forcing them to do two squeezes of the bottle and drive sales away. I also found it interesting that so much research goes into a shampoo bottle! I would think that all of the research just went into the shampoo itself but it makes sense that the product is useless if no one enjoyed the way the bottle feels or the way it is dispensed. 


Article2: ExoMars Prepares For Launch

When I first started watching this video my first thought was “WOW imagine the team work”.  I could not imagine how many different engineering backgrounds this task would require to complete this project. This goes to show why teamwork is necessary in the working world. There is no way one individual could complete such a project. 

I have always been so impressed by how astrophysicists are able to take such a limited amount of data and make accurate assumptions from them. For this ExoMars project they are will be able to take a detection of partials in the Martian atmosphere and plan to determine the history of Mars as well as if there is life. To me that seems crazy! I am always blow away when they show pictures from the Hubble telescope of some far away solar system that to me looks like two little blips of light but they can determine how many planets are in the galaxy by the reduction if light from the systems star! They said it would be equivalent to the light reduction from a fly crossing in front of a car headlight. 


Article3: Chipotle Shifts To Centralized Food Preparation Amid Outbreaks

The Chipotle saga continues. I was a big fan of Chipotle until their recent hiccups in food safety. It's going to be very challenging to bring back trust of former customers. Is this the fault of Chipotle that the outbreaks occurred? Or is Chipotle simply unlucky? Could this very same thing have happened to a different company/restaurant? It's been interesting to see the direction Chipotle will be headed and what steps they take to ensure this never happens again. This article sheds light on their process of vetting out the produce that comes into their restaurants. They always touted the message of locally grown produce but that may have bit them this time. Now they're looking to change their process by possibly implementing a centralized kitchen stations where produce and other foods would be tested, tracked, cut, and washed, then only sent out to the respective restaurants. Chipotle's "food with integrity" message of cultivating and harvesting good food, non-GMO based, and local grower initiatives are all great marketing messages and ways to get people in the door. It is a great example of trying to do the right thing on paper but that does not always lead to the best results. Sticking to this plan and executing it flawlessly is that much harder. It is really sad to see this company get stung by self inflected pain when only they were doing the right thing. But also, their stock was soaring. Did they lose site of quality over greed? I hope they can pull it together soon. I'm waiting and eager to be a customer again.

Q1. Explain what is QFD, (Quality Function Deployment)?

Ans. Quality Function Deployment (QFD) is a way to deal with item/administration plan and constant change that brings clients into the outline process. It is utilized to decipher what the client needs into what the association produces. The idea was initially grown by Dr. Yoji Akao in 1966, consolidating quality methodologies with components of worth designing. QFD requires the association of every practical division of the association toward the beginning of, and all through the venture. This is additionally an essential goal of TQM. There are numerous illustrations of items being conveyed to advertise just to be dismisses on the grounds that they didn't fulfill client needs/needs. A goal of QFD is to stay away from that disaster.
The four phases of QFD are:
1. Product concept planning. It starts with customers and market research with leads to product plans, ideas, sketches, concept models, and marketing plans.
2. Product development and specification. It would lead to the development to prototypes and tests.
3. Manufacturing processes and production tools. They are designed based on the product and component specifications.
4.  Production of product. It starts after the pilot has been resolved.

Q2. Explain the WHATs in a QFD matrix

Ans. The heart of QFD is the set of interrelated matrices known as the House of Quality (HOQ), so named because the complete matrix takes on the appearance of a house.
Ø  Gathering Customer Needs Input: The premise of QFD is that before any product or service is designed, the producer should have a good understanding of his potential customers’ needs in order to improve the likelihood that the product or service will be a market success. That the producer should be aware of customer needs seems logical, but it sounds far easier than it is.
Ø  Refining the Customer Needs Inputs: Once the cross-functional QFD team has assembled sufficient information on what characteristics, attributes and features customers say they need, the information must be distilled into something useful. Typically the problem is that the inputs invariably cover the spectrum from some really good ideas and nuggets of information to some that are trivial or frivolous, and the volume of information so great that the designers are unable to cope with it. The data must be sorted into a prioritized set of the most important customer needs.
Ø  Using the Affinity Diagram: Affinity diagrams are used to promote creative thinking. They can be very helpful in breaking down barriers created by past failures and in getting people to give up ingrained paradigms that impede our ability to find new and different approaches. This is a critical element in achieving continual improvement. Affinity diagrams give structure to the creative process by organizing ideas in a way that allows them to be discussed, improved, and interacted with by all the participants.
Ø  Using the Tree Diagram: The next tool to be used is the Tree Diagram. Tree diagrams can be used for countless purposes. It will be used here simply to refine the affinity diagram results to make the list the customer needs, or WHATs that will be placed in the HOQ. Although a tree diagram could go all the way down into the nuts and bolts of a new design, remember that the objective here is not to design the new product, but to list the items to be addressed by the design team once the entire HOQ is completed.
Ø  Customer Importance: Also coming out of the analysis is the team’s best estimate of the relative importance of each listed customer need. Customer importance is usually based on a scale of 1 to 5 with 5 being the highest priority. This information is solicited from customer sources, but unanimity in ranking by the customers is unlikely, so the team has to do its best to evaluate and assign priorities, as they believe the aggregate of customers would. These importance rankings are entered in the Customer Importance column.

Q3. Explain the HOWs in a QFD matrix
Ans. The Technical Requirements room of the HOQ states how the company intends to respond to each of the Customer Needs. It is sometimes referred to as the voice of the company. We must state at the outset that the technical requirements are not the design specifications of the product or service. Rather, they are characteristics and features of a product that is perceived as meeting the customer needs. They are measurable in terms of satisfactory achievement. Some may be measured by weight, strength, speed, and so on. Others by a simple yes or no, for example a desired feature, appearance, test, or material is or is not incorporated. The other side of the coin is that the technical requirements must not be limiting, but must be flexible enough to allow the company to consider every creative possibility in its attempts to satisfy the need. The technical requirements are generated by the QFD team through discussion and consultation with the Customer Needs and Planning matrices used as guidance. The team may use affinity or tree diagrams to develop, sort, and rank the requirements, similar to the Customer Needs development process. The difference here is that the input is from within the company rather than from external customers.

Q4. Explain the 1, or 3, or 9 interrelationship values in a QFD matrix.
Ans. The results will be shown in the Interrelationships matrix, which links the HOWs and the WHATs. At each intersection cell of the interrelationship matrix the team must assess the degree of relationship between the WHAT and the corresponding HOW. This is usually done using scales of significance of 1 to 5 or 1 to 9, with the higher number indicating a stronger relationship. Sometimes these numbers are entered, but often symbols are used.




Let’s see how this works. Refer to Figure above, and consider the first customer need, Comprehensible text. Now look at each of the intersections on that row to see which HOWs have a relationship with Comprehensible text. Authors/ Editors Guide seems to offer a relationship. Certainly the publisher’s guidance to the author, and the level and effectiveness of the editing process will impact the quality and comprehensibility of the text. We have identified an inter-relationship, but how strong is it? The team has to decide, and the result may not be very exact, but rather is a well- discussed estimate. Let’s say that the strength is high. We should enter either a “9” or the double-circle symbol in that cell. The next Comprehensible Text relationship cell appears to be under Text Clarity. The interrelationship between this WHAT and HOW is strong, so a 9 or the double-circle symbol is entered. All cells must be checked for interrelation- ships, and when such exists, the strength of the relationship must be evaluated.
As we have mentioned, either numbers or symbols may be used. If you use numbers, use only 1, 3, and 5 or 1, 3, and 9 rather than 1, 2, 3, 4, 5, and so on. Remember, we are only estimating the interrelationship’s strength: Is it strong, medium, weak, or nonexistent? There is little to be gained by trying to be precise in an area where the result is a best guess or an estimate.

Q5. Explain how you calculate the technical priorities in the design target matrix.

Ans. To determine the relative importance, or priorities, of each of the stated Technical Requirements (HOWs) in meeting the Customer Needs (WANTs), the QFD team simply multiplies each of the interrelationship ratings of the technical requirement (0, 1, 3, or 9) from the Interrelationship matrix, times the corresponding customer needs. Overall Weighting value in the Planning matrix; and then sums the columns. Moreover, some QFD users translate the priority values into a percentage scale. This is done, of course, by dividing the individual technical priority values by the sum of all the priority values, and multiplying by 100.
  % Total priority = (Technical Requirement Priority, Ʃ Technical Priorities) * 100
The rest of the % of Total Priority values are calculated and placed in a row just below the Technical Priorities. This information is used by the organization as guidance for the appropriate deployment of resources for the project.

Q6. Define statistical process control.

Ans. Statistical process control (SPC) is a statistical method of separating variation resulting from special causes from variation resulting from natural causes in order to eliminate the special causes and to establish and maintain consistency in the process, enabling process improvement.
Although SPC is normally thought of in industrial applications, it can be applied to virtually any process. Everything done in the workplace is a process. All processes are affected by multiple factors. For example, in the workplace a process can be affected by the environment and the machines employed, the materials used, the methods (work instructions) provided, the measurements taken, and the manpower (people) that operate the process—the Five M’s. If these are the only factors that can affect the process output, and if all of these are perfect—meaning the work environment facilitates quality work; there are no misadjustments in the machines; there are no flaws in the materials; and there are totally accurate and precisely followed work instructions, accurate and repeatable measurements, and people who work with extreme care, following the work instructions perfectly and concentrating fully on their work—and if all of these factors come into congruence, then the process will be in statistical control. This means that there are no special causes adversely affecting the process’s output.
SPC does not eliminate all variation in the processes, but it does something that is absolutely essential if the process is to be consistent and if the process is to be improved. SPC allows workers to separate the special causes of variation (e.g., environment and the Five M’s) from the natural variation found in all processes. After the special causes have been identified and eliminated, leaving only natural variation, the process is said to be in statistical control (or simply in control). When that state is achieved, the process is stable, and in a 3-sigma process, 99.73% of the output can be counted on to be within the statistical control limits.

Q7. Explain control charts for variables, with a simple mathematical example.

Ans. Consider an example using x-charts and R-charts. These charts are individual, directly related graphs plotting the mean (average) of samples (x) over time and the variation in each sample (R) over time. The basic steps for developing a control chart for data with measured values are these:
1. Determine sampling procedure. Sample size may depend on the kind of product, production rate, measurement expense, and likely ability to reveal changes in the process. Sample measurements are taken in subgroups of a specific size (n), typically from 3 to 10. Sampling frequency should be often enough that changes in the process are not missed but not so often as to mask slow drifts. If the object is to set up control charts for a new process, the number of subgroups for the initial calculations should be 25 or more. For existing processes that appear stable, that number can be reduced to 10 or so, and sample size (n) can be smaller, say, 3 to 5.
2. Collect initial data of 100 or so individual data points in k subgroups of n measurements. The process must not be tinkered with during this time—let it run. Don’t use old data—they may be irrelevant to the current process. Take notes on anything that may have significance. Log data on a data sheet designed for control chart use.
3. Calculate the mean (average) values of the data in each subgroup x.
4. Calculate the data range for each subgroup (R).
5. Calculate the average of the subgroup averages x. This is the process average and will be the centerline for the x -chart.
6. Calculate the average of the subgroup ranges R. This will be the centerline for the R-chart.
7. Calculate the process upper and lower control limits, UCL and LCL respectively. UCL and LCL represent limits of the process averages and are drawn as dashed lines on the control charts.
8. Draw the control chart to fit the calculated values.
9. Plot the data on the chart.
We calculate the mean (average) values for each subgroup. This is done by dividing the sum of x1 through x10 by the number of data points in the subgroup.




                                                                          

Where n = the number of data points in the subgroup. The x values are listed in the Mean Value column.
The average x of the subgroup average x is calculated by summing the values of x and dividing by the number of subgroups (k):





                                                                                                                                                             
The range (R) for each subgroup is calculated by subtracting the smallest value of x from the largest value of x in the subgroup.
R = (maximum value of x) – (minimum value of x)



From the R values, calculate the average of the sub-group ranges.



 

Q8. Explain control charts for attributes, with a simple mathematical example.

Ans. When a process is stable and in control, it displays common cause variation, variation that is inherent to the process. A process is in control when based on past experience it can be predicted how the process will vary (within limits) in the future. If the process is unstable, the process displays special cause variation, non-random variation from external factors. Attributes data are concerned not with measurement but with something that can be counted. For example, the number of defects is attributes data. Whereas the X – charts and R -charts are used for certain kinds of variables data, where measurement is involved, the p -chart is used for certain attributes data. Actually, the p -chart is used when the data are the fraction defective of some set of process output. It may also be shown as percentage defective. The points plotted on a p -chart are the fraction (or percentage) of defective pieces found in the sample of n pieces.
C-Chart used when identifying the total count of defects per unit (c) that occurred during the sampling period, the c-chart allows the practitioner to assign each sample more than one defect. This chart is used when the number of samples of each sampling period is essentially the same.



Used when each unit can be considered pass or fail – no matter the number of defects – a p-chart shows the number of tracked failures (np) divided by the number of total units (n).



Q9. Discuss and explain various continual quality improvement methods and tools.

Ans. Control charts of all types are fundamental tools for continual improvement. They provide alerts when special causes are at work in the process, and they prompt investigation and correction. When the initial special causes have been removed and the data stay between the control limits (within; 3s), work can begin on process improvement. As process improvements are implemented, the control charts will either ratify the improvement or reveal that the anticipated results were not achieved. Whether the anticipated results were achieved is virtually impossible to know unless the process is under control. This is because there are special causes affecting the process; hence, one never knows whether the change made to the process was responsible for any subsequent shift in the data or if it was caused by some- thing else entirely. However, once the process is in statistical control, any change you put into it can be linked directly to any shift in the subsequent data. You find out quickly what works and what doesn’t. Keep the favorable changes, and discard the others. As the process is refined and improved, it will be necessary to update the chart parameters. The UCL, LCL, and process average will all shift, so you cannot continue to plot data on the original set of limits and process aver- age.
An important thing to remember about control charts is that once they are established and the process is in statistical control, the charting does not stop. In fact, only then can the chart live up to its name, control chart. Having done the initial work of establishing limits and centerlines, plot- ting initial data, and eliminating any special causes that were found, we have arrived at the starting point. Data will have to be continually collected from the process in the same way they were for the initial chart.
This discussion of control charts has illustrated only the x-chart, R-chart, p-chart, and c-chart. Lists common control charts and their applications. The methods used in constructing the other charts are essentially the same as for the four we discussed in detail. Each chart type is intended for special application. You must determine which best fits your need.

Q10. Explain the way control charts could be used for quality improvements.

Ans. Continual improvement is fundamental to success in the global marketplace. A company that is just maintaining the status quo in such key areas as quality, new product development, adoption of new technologies, and process performance is like a runner who is standing still in a race. Competing in the global marketplace is like competing in the Olympics. Last year’s records are sure to be broken this year.
Athletes who don’t improve continually are not likely to remain long in the winner’s circle. The same is true of companies that must compete globally. Customer needs are not static; they change continually. A special product feature that is considered innovative today will be considered just routine tomorrow. A product cost that is considered a bargain today will be too high to compete tomorrow. A good case in point in this regard is the ever-falling price for each new feature introduced in the personal computer. The only way a company can hope to compete in the modern marketplace is to improve continually.

Article1: Are You Carrying a "Healthy" Inventory?
In the wake of perusing the eazystock article it has truly conveyed to light the amount of stock levels can influence an organization. On the off chance that the stock levels are too high, they are expending cash that could be required else were or utilized all the more proficiently to extend the organization. Then again if the stock levels are to low you could be making the client sit tight to yearn for their item and losing business to a contender. Neither of these choices are perfect and why a cheerful medium should be come to, yet it is difficult to stay right on the center line with request levels changing on a week to week premise.



Article2: How Winning This Contest Changed My Life
It really shows how others can bring out the best in someone. If it wasn't for that radio station DJ recognizing Oprah for her "voice", she may never have stumbled into broadcasting or TV. It goes to show that businesses and owners should take a chance in people who are motivated if they recognize something good. It doesn't mean everyone is going to turn out to be an Oprah, but if you believe in someone and recognize they have good traits that could help a company, give them a shot. We've all bumped into those people where we know they that person is going to be successful. It's a feeling that comes from within. However, there is some luck needed too as Oprah was in the right place at the right time. We could say what if this, what if that, but I suppose it was meant to be as she is a super successful individual. Very inspiring indeed.



Article3: Here’s the Scoop: Why My First Job Mattered
Indeed, I figure the President and I have something in like manner; one of my mid year employments was working at a frozen yogurt/froyo store. I trust dessert shops are quite often conspicuously utilized with children as their first employment. Frozen yogurt is a fun cheerful treat, and is dependably a tyke's most loved nourishment growing up so it bodes well to be starter work when one is the fate of age. Dessert scooping doesn't require a gigantic ability set, yet it can show high schoolers the significance and obligation of running a store. At the point when working at a dessert store, one should have the capacity to impart and associate not just with different representatives. in any case, clients, handle cash (which requires snappy thinking and math abilities), time administration, innovation aptitudes (utilizing an enroll, charge card machine, PDA applications), and association. The truth dessert is staple of youth, helps the move of starting to join the workforce. Teenagers are not threatened on the grounds that their associates are youngsters, and I know I was sufficiently fortunate to work with my companions. I for one cherished working at my dessert shop, and work was dependably fun! Yes, amid the warm summer evenings things got to be boisterous, however it helped the time pass and it tested me to be a superior representative! I'm perpetually fortunately to have worked there!
Summer of Opportunity is an extraordinary cause and I trust it extends the nation over and to numerous potential managers. Clearly, there are insufficient frozen yogurt stores to worker each high schooler in the nation and give them an energizing and fun first employment encounter. Also, then again adolescents are excessively youthful, making it impossible to acquire a late spring temporary position since they are not in school pressing together their degree. There should be a stage to help high schoolers stuck in this age hole to have a chance to acquire cash and pick up experience. Yes, a few adolescents in the nation require the employment for cash, however every teenager needs to hold an occupation to comprehend the obligations that accompany it. In addition, it can be put on their resume when they are in school or even after to show they have determination and comprehend what its get a kick out of the chance to hold a position. When somebody needs to surpass they need to be given a risk, an open door, and this program can give them a kick off.
