Project Management OUTLINE Task Clarify the task, Elaborate the specification Identify essential problems, Establish function structures, Search for solutions principles, Combine and firm up into concept variants, Evaluate against criteria Specification Concept Develop preliminary layouts & form designs, Select best preliminary layouts, Refine and evaluate against criteria Preliminary layout Optimize & complete form designs, Check for errors and cost effectiveness, Prepare preliminary parts and production doc. Definitive layout Finalize details, Complete detail drawings and production document, Check all documents. Documentation Solution Upgrade and improve Detail design Embodiment design Clarificationof the task Conceptual design Optimization of principle Optimization of layout and forms [From Pahl and Beitz 1984] How to define the problem clearly and unambiguously? How to construct specifications? How to generate concepts?
