Did You Think About That?
A systematic design review checklist for engineers — 100+ items across nine categories, covering everything from load paths to serviceability. Run it before you release to manufacturing and catch what you missed.
Not a form to fill out for someone else. A tool to pressure-test your own design.

9 Categories + Final Gate
Structure & Geometry
Load paths, clearances, tolerance stack-ups, datum schemes, stiffness, resonance, and sealing.
Materials & Selection
Material justification, galvanic pairs, thermal expansion, chemical compatibility, and regulatory compliance.
Load & Environment
Static and dynamic loads, fatigue, safety factors, temperature, moisture, EMI, and sterilization.
Manufacturability
Process selection, tool access, part count, poka-yoke, draft angles, radii, and fixture planning.
Joining & Fastening
Fastener specs, thread engagement, torque specs, adhesive bonds, and weld specifications.
Inspection & QC
Critical dimensions, measurement methods, first article inspection, functional testing, and traceability.
System Integration
Electrical and fluid routing, thermal management, BOM management, and change order tracking.
Safety & Risk
Sharp edges, fail modes, regulatory, DFMEA, stored energy, and lockout/tagout.
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
Enter your project name
Name the design review so you know what you're checking against.
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.
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.
Want a Custom Design Review for Your Team?
This is a general-purpose checklist. If your team needs a review tool built around your specific products, processes, and regulatory requirements — let's build it.
