Quality Function Deployment
8 important questions on Quality Function Deployment
! Was ist QFD? Wofür wird es eingesetzt?
Primary Objectives:
- Understand Customer Requirements
- Determine in advance how Costumer will judge a products value in order to design it
- Obtain cross functional agreement and "buy-in" on the customer needs (Marketing, Engineering, Management, Manufacturing, Quality, etc.)
- Translate Customer needs into development goals and technical capabilities
- Focus on characteristics from the viewpoints of market segments, company, or technology-development needs
- Provide Documented Requirements Traceability
! Wie gehe ich vor?
- Product Planning
- Product Design
- Process Planning
- Process Control
- Each phase the QFD is represented by a chart matrix (house) throughout the entire system life cycle
- used for the first phase in the QFD process – the Product Planning phase
- helps product designers to identify customer requirements, relate them to engineering characteristics, identify tradeoffs, and to evaluate the characteristics of a potential product relative to competing products.
- is a kind of conceptual map that provides the means for inter-functional planning und communications
- translates customer needs into development goals and technical capabilities
! Was ist der Nutzen von QFD?
- ... for engineers it is a way to summarize basic data in usable form
- ... for marketing executives it represents the voice of the customer
- ... for general managers it is used to discover strategic opportunities
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
!!! Welche Informationen benötige ich hierfür?
- What do customers really want? Customer Attributes (CA)
- Are all preferences equally important? Relative Importance (RI)
- Will delivering perceived need yield a competitive advantage? Customer Perceptions
- How can we change the product? (Engineering Characteristics (EC) & Objective Measures
- How much does engineering influence customer-perceived qualities? Relation Matrix
- How does one engineering change affect other characteristics? Roof Matrix
- How can we add customized data and information? Customer build part
! Will delivering perceived need yield a competitive advantage?
- To match or exceed a companies competition the company must first know where their product stands relative to their competitors (customer perceptions)
- Comparison with the competition can identify opportunities for improvement
- Identify possible and existing advantages for Customer Attributes, which are important to gain or maintain
- This section provides a natural link from product concept to a company’s strategic vision
! How can we change the product?
- Engineering Characteristics tell how to change the product in the language of the engineer (product description in measurable terms)
- List Engineering Characteristics that directly affect Customer Attributes
- The signs mean that increasing (+) or reducing (-) the specific Engineering Characteristic is improving product quality
- Add Objective Measures at the bottom of the house beneath the Customer Attributes
- Determine Measurement Units for each Engineering Characteristic and estimate “our- own” product
- Comparison with competitors by measuring their products for each Engineering Characteristic using the determined Measurement Units
- Yields an engineering stand relative to their competitors
! How much does engineering influence customer-perceived qualities?
- The Relationship Matrix shows how much each Engineering Characteristic (EC) affects each Customer Attribute (CA)
- If a EC affects no CA, it may be redundant to the EC list on the house, or you may have missed a Customer Attribute
- A CA unaffected by any EC presents opportunities to expand EC
- strength of each of these relationships is established by numbers or symbols
- check marks for positive and crosses for negative relationships
- different colors which indicate a strong (black) and a medium (grey) strength of relationship
! How does one engineering change affect other characteristics?
- Engineering is creative solutions and a balancing of objectives
- house of quality’s Roof Matrix helps engineers specify the various engineering features that have to be improved and their relationship
- The Roof Matrix facilitates the balance of engineering trade-offs when addressing customer benefits
- strength of each of these relationships is established by numbers or symbols
- use check marks for positive and crosses for negative relationships
- different colors which indicate a strong (black) and a medium (grey) strength of relationship
