QFD (Quality Function Deployment) introduction,
Concept of QFD, History of QFD, Traditional systems & Development of QFD, Technical story as for QFD, Scope of QFD, Benefits of QFD, where does QFD fits, when to use QFD, House of quality (HOQ) model in QFD, relationship matrix of QFD, QFD overview, References, Conclusion

1. By  KAMAL JOSHI QFD

2. Objective of Presentation: To explain - The Concept of QFD - Development of QFD To highlight - When & Where a QFD - Scope of QFD To explore the HOQ model in QFD

3. = QFD HIN SHITSU Quality Features Attributes KI NO TEN KAI Deployment Diffusion Development Function Mechanization QFD - From the Japanese : Quality: Meeting Customer Requirements Function: What must be done – Focusing the attention Deployment: Who will do it, When

4. History & Development:  Originally developed in Japan by “Yoji Akao” in 1966. First implemented at the Kobe Shipyard of Mitsubishi Heavy Industry in 1972. First QFD Training outside Japan at General Motors Corporation and Ford in 1983. QFD - History

5. History & Development Cont... QFD - History

6. OK, Let’s Walk Through A Technical Story

7. A Technical Story: The “Insulation and Sealing” Engineer I have developed a new Cabin Sunroof seal I will make a simpler lever The “Handles and Levers” Engineer WOW!!!!! Engineer 1 Engineer 2 Heavier roof due to increased insulation Lighter than old one Problem Analysis:

8. A Technical Story: One or both components will need to be redesigned Need to be reworked Have to be recalled Problem Detection: Teamwork and common objectives

9. UNEXPECTED, PLEASANT SURPRISES Spoken Measurable Range of Fulfillment Unspoken Taken For granted Basic Spoken If Not Met QFD focuses on Performance Needs and Basic Needs Where does QFD fit?

10. When should QFD be used? Customer Dissatisfaction Excessive redesign Complex Product Development Poor functional communications

11. Four stages of a QFD Project: Complete the house of quality (HOQ) Design the product (Product Specifications) Design the process (Production procedures) Control the process (Quality Standards) QFD Project:

12. Foundation of a House of QFD Basic graphic diagram for any house of quality resembles this one: Co-relationships Technical requirements Interrelationship matrix   Customer Requirements Technical attributes Technical evaluation Imp. Ratings Competitive Assessment

13. Waterfall Relationship of QFD Matrix

14. Customer Requirements Company Measures Part Characteristics (Design) Manufacturing Process Production Requirements (Day to Day Operations) QFD Overview: Converted to Converted to Converted to Converted to

15. Benefits of QFD Fewer and Earlier Changes Fewer Start-up Problems Lower Start-up Cost Knowledge Transfer Customer Satisfaction

16. Scope of QFD: Everywhere At Anytime On Everything

17. Conclusion: Quality Function Deployment : A comprehensive quality system . An extremely flexible methodology. A systematical link between customer needs and various business functions. QFD seeks both spoken and unspoken true customer needs.

20. New management planning tools are defined as the method(s) for achieving expected outcomes that previously have not been used. In 1976, the  Union of Japanese Scientists and Engineers (JUSE)  saw the need for tools to promote innovation, communicate information, and successfully plan major projects. A team researched and developed these seven new quality control tools, often called the seven management and planning tools, or simply the seven management tools: Affinity diagram : Organizes a large number of ideas into their natural relationships. Interrelationship diagram : Shows cause-and-effect relationships and helps analyze the natural links between different aspects of a complex situation. Tree diagram : Breaks down broad categories into finer and finer levels of detail, helping to move step-by-step thinking from generalities to specifics. Matrix diagram : Shows the relationship between two, three, or four groups of information and can give information about the relationship, such as its strength, the roles played by various individuals, or measurements. Matrix data analysis : A complex mathematical technique for analyzing matrices, often replaced by the similar prioritization matrix. A prioritization matrix is an  L-shaped matrix  that uses pairwise comparisons of a list of options to a set of criteria in order to choose the best option(s). Arrow diagram : Shows the required order of tasks in a project or process, the best schedule for the entire project, and potential scheduling and resource problems and their solutions. Process decision program chart : Systematically identifies what might go wrong in a plan under development. 7 new Mgt. & Planning Tools
