Design reviews are structured evaluations of the design at key milestones. They provide independent verification that the design meets requirements before committing to the next phase.
| Review | When | Key questions |
|---|---|---|
| System design review (SDR) | End of concept phase | Does the architecture meet top-level requirements? Are risks identified? |
| Preliminary design review (PDR) | End of preliminary design | Is the design approach feasible? Are interfaces defined? |
| Critical design review (CDR) | End of detailed design | Is the design complete enough to build? Does analysis show margins are adequate? |
| Production readiness review (PRR) | Before production | Is the manufacturing process ready? Is tooling qualified? |
