1 Module K Quality Function Deployment CC ppt

2 QFD Overview Objectives Define QFD List benefits of QFD Outline QFD matrix process Summarize CC ppt

3 Quality Function Deployment Quality What the customer/user needs or expects Function How those needs or expectations are to be satisfied Deployment Making it happen throughout the organization CC ppt

4 Multiple customers Competing alternatives Multiple suppliers Decision Analysis Provides Focus Multiple objectives * Quality Function Deployment Communication Multiple disciplines Conflicting interests Decision Analysis and QFD provide more customer interaction and a better product Consensus common terminology List of potential trades ranked priorities Documentation CC ppt

5 QFD Origins and Usage HIN SHITSU KI NO TEN KAI Quality Function Deployment Originated in early 1970's at Mitsubishi's Kobe shipyard Used worldwide by the automotive industry (Ford Taurus) Wide use by Japanese consumer electronics industry Increasing use by U.S. computer/electronics industry Increasing use by U.S. defense community customers and suppliers DoD TQM guidebook G IDA report on concurrent engineering Increasing recognition as an effective mechanism for strategic planning and process improvement CC ppt

6 QFD Overview Objectives Define QFD List benefits of QFD Outline QFD matrix process Summarize CC ppt

7 Key Benefits of QFD Quality Allows organization and leveling of requirements Helps optimize product and process designs Cost Streamlines requirements iteration process Reduces number of engineering changes Shortens product development cycle Communication Emphasizes the Voice of the Customer Provides common language and data base Promotes understanding of multi-discipline requirements Documentation Provides continuous, comprehensive evaluations and sensitivities Produces a detailed/living documentation trail CC ppt

8 QFD Contributes to Quality Improvement Identify Needs Plan, Prioritize, Focus Make Improvements Hold the Gains Satisfy Needs Customer Quality Function Deployment Design of Experiment s (Taguchi) Statistical Process Control Product Cost of Design Changes QFD is best used here Production Begins Time QFD is part of Total Quality Management Recognized and accepted process Ready-made sales tool 0 CC ppt

9 QFD Can Support the Entire Product Development Cycle Customer expectations Design specification Part characteristics Manufacturing operations Production requirements QFD can help structure strategy, programs and products CC ppt

10 When Is QFD Helpful Focus on People Multiple customers or users Conflicting customer priorities Multiple disciplines involved User requirements not quantifiable Focus on Solutions Multiple feasible solutions Solutions conflict with each other Solution not yet quantified Everyday problems! CC ppt

11 QFD Analysis Products A prioritized list customer wants (requirements) A prioritized list of how you may satisfy the customer s wants (solution) A common set of definitions for requirements and solutions A list of potential trades A basis for identifying and selecting concepts More customer interaction Leads to a better product CC ppt

12 QFD Overview Objectives Define QFD List benefits of QFD Outline QFD matrix process Summarize CC ppt

13 Decision Analysis Using QFD QFD is a structured, matrix-based process for exploring solutions to complex problems Articulate and define problems - WHAT specifics are desired? Determine relative importance of each to the owner Survey the range of solutions - HOW are specifics achieved? Access value/importance of solutions Decompose solutions into next set of WHATs and HOWs Each assessment and decision is documented. All steps are easily traced CC ppt

14 QFD Is Documented in a House of Quality The QFD process is designed to emphasize drivers, not details WHATs HOWs Prioritized HOWs Pritorized WHATs QFD is not difficult but experience is helpful CC ppt

15 The House of Quality Is Completed Using a Sequence of Steps These steps are typical of most QFD applications 0 Identify scope, constraints, and groundrules 1 Identify the customer requirements (WHATs) 2 Prioritize customer requirements 3 Identify the competing solutions (HOWs) 4 Relate HOWs to WHATs 5 Correlate the competing solutions (HOWs) 6 Evaluate the competing solutions (HOWs) 7 Flowdown to next QFD matrix Don t forget definitions 5 (if necessary) CC ppt

16 Design specifications Flow Down Matrices to Increase the Level of Detail Customer requirements Product planning matrix Design specifications Part characteristics Part deployment matrix Part characteristics Makabe System American Supplier Institute Template - automobile industry Manufacturing operations Process planning matrix Manufacturing operations Production requirements Production planning matrix CC ppt
