Design & Engineering

Software: Core functionality implementation

Hardware: Prototype 1 units with rapid prototyped components

Test: Engineering confidence test, unit test

NPI

MFG: Readiness: Project build plan CM selection

Quality: Critical manufacturing process identification

2B. Prototype 1 Design, Build And Test

The detailed design phase usually has multiple, iterative sub-phases as the design progresses and representative prototypes are built. Phases 2B and 2C are typically the largest efforts in the product development process, where the specific implementation for all disciplines occurs (mechanical, industrial design, electrical, firmware, systems, software, manufacturing, and quality).

Simplexity typically engages with production component suppliers and contract manufacturing groups early in this phase to provide additional manufacturing input on the design. If the product has stringent testing or certification requirements, pre-screens are performed in this phase prior to formal regulatory agency testing.

Typical deliverables:

• Prototypes (3D printed or other rapid prototypes, electrical PCAs, and/or preliminary code)
• Software and hardware design documentation
• Initial product firmware or software binaries and source code
• Electrical schematics and layout
• 3D CAD files
• Design failure mode and effect analysis
• Test plans and reports
• Project build plan – from prototype to pre-production
• Initial Bill of Materials (BOM) and Cost of Goods Sold (COGS)
• Manufacturing process identification
• Contract Manufacturer (CM) selection

Gate definition:

• Engineering confidence test reviews
