This is an example of a matrix that defines the various product builds defined in an organizations development process and the criteria related to each build.
| Build Criteria | P0 Build | P1 Build | P2 Build |
| Development Phase | 2 | 3 | 4 |
| Prerequisites | Preliminary design review | Released drawings | Production readiness review |
| Typical build quantity | 2 | 10 | 20 |
| Nature of parts | Functionally similar (e.g., surrogate parts, rapid prototype parts, FPGA vs. ASIC) | Design intent per drawing (meet functional & physical requirements) | Production parts from intended supplier’s production process |
| Supplier Used | Any (prototype house or actual supplier) | Actual supplier | Actual supplier |
| Supplier production process | Non-production or production process/line | Non-production or production process/line | Intended production process & line |
| Production Location | Lab | Pilot or low-volume line in Production | Intended production line |
| Tooling, fixtures & test software | None | Prototype/low-volume tooling, fixtures & SW | Final/production-ready tooling, fixtures & SW |
| Qualification Test/ Verification | Functional only | All – functional, reliability & environmental | All – functional, reliability & environmental |
| Verification subject | Product | Product & process | Process |
