The Generic Design Process Concept Development Planning Mission Approval System Level Design Concept Review Testing and Refinement Detail Design System Spec Review Critical Design Review Production Ramp-Up Production Approval The Design Process with Multiple Subsystems Concept Development Planning Mission Approval System Level Design Concept Review Design Test Integrate & Test System Spec Review Production Ramp-Up Production Approval Key Activities During the Design Process v PHASE 0 PLANNING v PHASE 1 CONCEPT DEVELOPMENT v Define customer base / market segments v Collect v Generate customer needs alternate concepts v Create team mission statement v Define project timeline v Consider platform and architecture v Identify constraints v Identify competitive products v Investigate feasibility of concepts v Build & test experimental prototypes v Estimate manufacturing cost v Assess manufacturing / fabrication feasibility v Perform patent searches v PHASE 2 SYSTEM LEVEL DESIGN v Define major systems and subsystems v Define subsystem interfaces v Identify material sources / suppliers v Perform make vs. buy analysis v PHASE 3 DETAIL DESIGN / TEST v PHASE 4 INTEGRATE & TEST v PHASE 5 PRODUCTION RAMP-UP v Separately Design / Build / Test each subsystem v Facilitate field testing v Field test prototype(s) v Perform reliability v Select / acquire testing materials v Define part geometry v Assign tolerances v Define circuitry / component layout v Design / implement software v Define / execute test plans Adapted from Product Design and Development by Karl Ulrich and Steven Eppinger (Mc. Graw-Hill/Irwin) by Mark Anderson, The Design Lab at Rensselaer v Performance testing v Implement design changes v Refine fabrication and assembly v Refine Quality Assurance plan v Evaluate prototypes v Evaluate early production prototypes v Begin operation of entire production system v Note that this phase is typically not reached during student projects
