Unformatted text preview: Engineering Evaluation: Developing and Using a Pugh Matrix Talk originally developed by Maria Oden, Ph.D. Engineers and Decisions • What criteria do engineers use when making decisions? – Based on facts? – Based on gut instinct? – Based on opinions? – Based on political gain? • How do you make decisions? Rational Approaches • Problem solving (Ch. 3) – Lecture next Tuesday • Design process (Ch. 5, PBL 3) • Evaluation – Pugh Matrix Good engineers place a systematic process on top of messy problems as a way to get solid answers. Design Process Plan the process to stay on track Document/Communicate Develop Solution Options Implement Solution Test/Evaluate Implemented Solution Evaluate Solutions Iterate: refine and improve based on evaluation Solution Stage Clarify Team Assignment Understand Problem and Context- Identify why design is needed- Identify current techniques used to solve problem - Identify constraints on design- Identify user needs for design Define design goals or criteria Design Analysis Stage For PBL Case 1 Plan the process to stay on track Document/Communicate Develop Solution Options Implement Solution Test/Evaluate Implemented Solution Evaluate Solutions Iterate: refine and improve based on evaluation Solution Stage Clarify Team Assignment Understand Problem and Context- Identify why design is needed- Identify current techniques used to solve problem - Identify constraints on design- Identify user needs for design Define design goals or criteria Design Analysis Stage Analysis Stage • Why is the design important? • What is being done now? • What are the minimum set of real constraints on the design? • What is most important to the user? • What niche can this design fill? E.g. ipod nano Clarify Team Assignment Understand Problem and Context- Identify forces driving the design- Identify current techniques used to solve problem - Identify constraints on design- Identify user needs for design Define design goals or criteria Design Analysis Stage Defining Design/Evaluation Criteria Clarify Team Assignment Understand Problem and Context- Identify forces driving the design- Identify current techniques used to solve problem- Identify constraints on design- Identify user needs for design Define design goals or criteria Design Analysis Stage • Translate what is learned in previous steps into quantitative criteria ....
