Mechanical Design Review Readiness Checklist.

A concise gate review for product architecture, detailed design, production readiness, and release evidence.

01 · Requirements

User, operating states, and success criteria are explicitCritical assumptions and unresolved questions are visibleInterfaces and owners are definedRequirements are measurable and traceable

02 · Loads + physics

Load cases, boundary conditions, and misuse states are documentedFree-body diagrams close complete load pathsStrength, stiffness, stability, fatigue, and thermal effects are addressedMargins match uncertainty and consequence

03 · Motion + interfaces

Degrees of freedom and constraint strategy are deliberateFits, clearances, backlash, friction, wear, and hard stops are evaluatedMoving envelopes and jam states are reviewedService and replacement preserve function

04 · Tolerances

Datums follow function and assemblyCritical stacks close mathematicallyTolerance values match process capabilityInspection can verify each critical characteristic

05 · Production

Material and process assumptions match volumeAssembly order, access, joining, and error proofing are credibleSupplier feedback is closed by design ownershipCAD, drawings, specifications, and bill of materials agree

06 · Evidence + release

Prototype fidelity and limitations are recordedTests map to requirements and pass criteriaFailures have corrective action and retest evidenceResidual risks, configuration, and release authority are documented
