Stages In The Design Process Idea Generation Product Concept Feasibility Study Performance Specifications Preliminary Design Prototype Final Design Final Design Specifications Process Planning Manufacturing Specifications
Design & Manufacturing The Design Process Product feasible? Idea generation Feasibility study Yes Preliminary design No Final design Process planning Prototype Manufacturing Design & Manufacturing Specifications
Idea Generation Suppliers, distributors, salespersons Trade journals and other published material Warranty claims, customer complaints, failures Customer surveys, focus groups, interviews Field testing, trial users Research and development
Feasibility Study Market Analysis Economic Analysis Technical / Strategic Analysis
Preliminary Design Create form & functional design Build prototype Test prototype Revise prototype Retest
Final Design & Process Planning Produce detailed drawings & specifications Create workable instructions for manufacture Select tooling & equipment Prepare job descriptions Determine operation & assembly order Program automated machines
An Effective Design Process Matches product/service characteristics with customer needs Meets customer requirements in simplest, most cost-effective manner Reduces time to market Minimizes revisions
Improving The Design Process 1. Design teams & concurrent design 2. Design for manufacture & assembly 3. Design for environment & sustainability 4. Design for robustness & quality
