9 Categories + Final Gate

1. Structure & Geometry — Load paths, clearances, tolerance stack-ups, datum schemes, stiffness, resonance, and sealing.
2. Materials & Selection — Material justification, galvanic pairs, thermal expansion, chemical compatibility, and regulatory compliance.
3. Load & Environment — Static and dynamic loads, fatigue, safety factors, temperature, moisture, EMI, and sterilization.
4. Manufacturability — Process selection, tool access, part count, poka-yoke, draft angles, radii, and fixture planning.
5. Joining & Fastening — Fastener specs, thread engagement, torque specs, adhesive bonds, and weld specifications.
6. Inspection & QC — Critical dimensions, measurement methods, first article inspection, functional testing, and traceability.
7. System Integration — Electrical and fluid routing, thermal management, BOM management, and change order tracking.
8. Safety & Risk — Sharp edges, fail modes, regulatory, DFMEA, stored energy, and lockout/tagout.
9. Serviceability — Field repair, wear items, spare parts, diagnostic access, and end-of-life planning.

Plus a Final Gate section covering cost & schedule, drawing completeness, special processes, documentation, and pre-release checks.

How It Works

1. Enter your project name — Name the design review so you know what you're checking against.
2. Work through each category — Each item can be checked (addressed), marked N/A (not applicable), or left unchecked (needs attention). Progress tracks in real time at the top.
3. Print your review — When you're done, generate a print-ready summary with an N/A reasoning page — blank lines for written justification on every item you marked not applicable.

This tool does not save state between sessions — treat each review as a focused, start-to-finish exercise. Print your results when you're done.

Every Engineer Who's Been Burned by "I Thought Someone Checked That"

• Design engineers running a self-review before handing off to manufacturing or a formal design review.
• Engineering managers who want a consistent, repeatable review process across their team.
• Startups and small teams without a formal design review process — this gives you one immediately.
• Contract engineers using this as a quality gate before delivering to a client.
