The Product Development Process

Starting point
New product
Existing Product
Market Research
Concept Feasibility Study
Product Specification
From existing requirements
Regulatory Requirements
Specific Customer Requirements
(these are often vague and conflicting)
Initial Design Sequence
Material and Components
Selection and Sourcing
Supply Chain Logistics
Make/Buy Analysis
FMEA (Failure modes and effects analysis)
Prototype Evaluation
Focus groups
Manufacturing Evaluation and Planning
Design Refinement
Prototype Testing
Tooling Development
Production Planning
Transition into production
Production Part Approval Process
Capability Analysis
First article approval
Close the loop – Evaluate
