ECU

Phase 5 – On-going Production and Design Maintenance

Continue with production runs

Maintain design as components become obsolete

Phase 4 – Manufacturing Engineering and First Production

Manufacturing engineering for production

Develop manufacturing test fixture and test procedure for system

Build first small production run (50-100 systems)

Phase 3 – System Evaluation, Testing and Refinement

Test and evaluate Engineering Prototype systems in laboratory and field situation

Revise system design if required

Develop unit pricing for complete systems in production quantities

Sign-off on design and move into production

Phase 2 – System Design and Development

Hardware, firmware, software and App development

Mechanical design of the system (enclosure, packaging, wire harness design, etc.)

Integrate electronic hardware, software and firmware into complete system for testing

Build Engineering Prototype (EP) system(s) for evaluation by PE and customer

Phase 1 – Discovery and Planning

Upfront research and development (if required for new technologies)

Design of overall system architecture and layout

Detailed product specification development
