EDGE™ Concept Development & Selection Session Learning Objectives 1.Understand concept selection matrix - one of the most widely used decision tools in product development. 2.Reinforce importance of concept selection within product development process 3.Expose SD1 students to alternative methods for selecting product concepts

EDGE™ Concept Development & Selection Process Perform Economic Analysis Benchmark Competitive Products Build and Test Models and Prototypes Identify Customer Needs Establish Target Specifications Generate Product Concepts Select Product Concept(s) Set Final Specifications Plan Downstream Development Mission Statement Test Product Concept(s) Development Plan Karl T. Ulrich and Steven D. Eppinger, 2004, Product Design and Development, Exhibit 7-2, Chapter 7, 3 rd Edition, Irwin McGraw-Hill

EDGE™ Concept Ratings Selection Criteria Winning Concept(s) Concept Development & Selection Process Goal: The goal is not to select the best concept but to develop the best concept by combining and/or refining Concepts Screening Stage Scoring Stage

EDGE™ Concept Selection Example: Reusable Syringe Karl T. Ulrich and Steven D. Eppinger, 2004, Product Design and Development, Exhibit 7-1, Chapter 7, 3 rd Edition, Irwin McGraw-Hill

EDGE™ Concept Selection Example: Reusable Syringe Design an improved, reusable syringe with precise dosage control for outpatient use.Design an improved, reusable syringe with precise dosage control for outpatient use. –Current product was too costly and inaccurate Seven criteria identified based on stake holder needsSeven criteria identified based on stake holder needs –Ease of handling, use and manufacture –Readability of dose settings and accuracy –Durability and portability Refer to Exhibit 7-3 for seven concepts proposedRefer to Exhibit 7-3 for seven concepts proposed

EDGE™ Screening Stage Prepare the Matrix – Pugh's METHODPrepare the Matrix – Pugh's METHOD –Criteria –Select Reference Concept Rate ConceptsRate Concepts –Scale (+ – 0) –Compare to Reference Concepts Rank ConceptsRank Concepts Combine and ImproveCombine and Improve –Remove Bad Features –Combine Good Qualities Select Best ConceptsSelect Best Concepts –May Be More than One –Beware of Average Concepts Reflect on the ProcessReflect on the Process –Continuous Improvement Refer to Textbook Exhibit 7-5

EDGE™ Scoring Stage Prepare the Matrix – Pugh's METHODPrepare the Matrix – Pugh's METHOD –Criteria –Weightings Rate ConceptsRate Concepts –Scale (1 - 5) –Select “Average” Criteria for Reference –Compare to Reference Criteria Rank ConceptsRank Concepts –Sum Weighted Scores Combine and ImproveCombine and Improve –Remove Bad Features –Combine Good Qualities Select Best ConceptsSelect Best Concepts –May Be More than One –Beware of Average Concepts Reflect on the ProcessReflect on the Process –Continuous Improvement Refer to Textbook Exhibit 7-7

EDGE™ Tips for Concept Development & Selection When possible, use objective rather subjective criteriaWhen possible, use objective rather subjective criteria Useful to identify strengths of concepts that do not make it through screening/scoring stages – could these be incorporated on winning concept(s)?Useful to identify strengths of concepts that do not make it through screening/scoring stages – could these be incorporated on winning concept(s)? Include ease of manufacture or cost as criteriaInclude ease of manufacture or cost as criteria Use concept development & selection process throughout SD1 and SD2Use concept development & selection process throughout SD1 and SD2
