Using Case Studies to Teach Engineering Design and Ethics Larry G. Richards and Michael E. Gorman University of Virginia ASEE 2004: Session 3441
Case Studies • What are Cases? • a narrative account of a situation, problem, or decision • usually derived from actual experience • reflect real-world concerns
Case Studies • And why should we use them? • To develop higher level thinking skills • beyond rote learning • require analysis, judgment, decisions • perspective taking, role playing • independent thought, critical thinking
Case Studies • And why should we use them? • To expose students to realistic situations • open ended problems • multiple possible answers • key decision points • tradeoffs involved in practice
Approaches to developing knowledge and skills (Shapiro) • Lectures and readings • “acquiring knowledge and becoming informed about techniques” • Exercises and problem sets • “the initial tools for exploring the applications and limitations of techniques”
Approaches to developing knowledge and skills (Shapiro) • Case method • “development of philosophies, approaches and skills” • Extend the learning experience beyond the classroom and laboratory.
University of Virginia Cases • Darden case library • Invention and design • Environmental design • Ethics • Systems engineering • Integrated Product Development
Focus on Ethics • Moral reasoning • Mental Models • Moral Imagination
Mental models • Mental representations, internal images or verbal codings of experience, cognitive frameworks • Set the parameters through which experience is filtered and organized • “May limit us to familiar ways of thinking and acting” • “inhibit consideration of alternatives”
Limited perspectives • Standard solutions • Accepted ways of doing things • Compartmentalized expertise • Corporate culture
Moral imagination • “Moral imagination involves recognizing the role, scheme, or mental model that one is adopting, disengaging from it, and evaluating alternative perspectives and courses of action.” • Gorman, Mehalik, Werhane, p.2
Real life cases • “…students need to see multiple examples of how ethical dilemmas are handled in the real world” • “They also need to see the kind of detailed information available to actual decision makers.” • Gorman, Mehalik, Werhane, p.1
Case study approach • “Cases constitute a kind of virtual apprenticeship, in which students can apply ethical principles to actual situations and discuss the outcomes with each other and with a faculty mentor.” • Gorman, Mehalik, Werhane, p.2
Some Ethical Issues in Engineering Practice • Best design standards • Patent infringement • Product liability • Environmental Sustainability • Appropriate technology • Engineering disasters
The Westinghouse Example • John Kamauff (graduate student) • Landel and Richards (faculty advisors) • Funded by National Consortium for Technology in Business (ASEE and AACSB)
Westinghouse Case • Introduce new philosophy • Integrated product development • Mandated by management • Required organizational changes within the company • How to build trust among all the parties
Westinghouse Case • Traditional functional areas • Marketing • Manufacturing • Design Engineering • Systems design and development • Quality assurance • Different roles; different perspectives • Now must work on multidisciplinary teams.
DesignTex, Inc • Matt Mehalik (graduate student) • Mike Gorman, Andrea Larson, Patricia Werhane (faculty) • Based on the work of William McDonough • Design of environmentally friendly fabrics.
McDonough • Former Dean of Architecture at UVA • Major proponent of sustainable design • Two principles: • Waste equals food • Cradle to cradle design • Environmentally intelligent
Details of the DesignTex case • Design and manufacture of textiles for commercial interiors • Steelcase office furniture • Portfolio collection • Rohner Textil • Suppliers (dyes, materials)
DesignTex case • Sue Lyons (VP of DesignTex) • William McDonough (architect/designer) • Michael Braungart (chemist) • Albin Kalin (Rohner Textil)
Issues involved in the case • Sustainability • Aesthetics • Standards • Industrial ecology • Production processes • Costs • Tradeoffs
Changing jobs • Mini-cases developed by B. Garrey and M. Gorman, 2002. • An engineer moving from one company to another • A group of engineers moving from one company to another.
Changing jobs • Initial description seems to lead to a fairly clear cut decision. • But as details are added, the situation becomes murkier. • At the end of the discussion, Mr. Garrey gives students: • Tips on how to change jobs without getting sued. • Tips on working for your new employer
