Design Reviews Don't Fail Because of Bad Designs
I've sat through design reviews where the engineering was solid — and the review still failed.
Not because the design was wrong. Because the process was broken before anyone opened a slide.
Here's what actually kills design reviews:
No entry criteria. Half the data packages aren't ready. Two hours later, the conclusion is "we need another review." That's not a review. That's a status meeting.
No exit criteria. Nobody defined what "pass" looks like. The decision becomes a debate. Everyone leaves with a different understanding.
No action tracking. Fifty comments get raised. They go into meeting notes that nobody reads again. Three months later, the same issues resurface during test.
Wrong people in the room. A review without your test engineer misses testability. A review without your DER misses compliance gaps. The invite list matters more than the slide deck.
None of these are engineering problems. They're process problems. And they're fixable — if you define the structure before the review starts.
The Fifth Killer: Scope Creep
There's one more that deserves mention. Someone asks "while we're here, can we also look at..." and suddenly a PDR becomes an unplanned CDR. The original objectives never get addressed. A good review chair keeps the scope locked — this requires someone who understands the review objectives, not just a moderator.
How to Fix This
The solution isn't more reviews. It's better-structured reviews.
Define entry criteria in writing. Before the review is scheduled, publish a checklist: data packages complete, RIDs distributed, pre-review comments collected. If the entry criteria aren't met, the review doesn't start. This one rule alone eliminates most wasted reviews.
Define exit criteria in writing. What does "pass" mean? All Category 1 RIDs resolved? No open safety findings? Verification approach agreed? Put it on paper before the review begins.
Track actions with owners and due dates. Every Review Item Discrepancy gets an owner, a due date, and a severity classification. Review the RID closure status at the next milestone. No closure, no progression.
Lock the scope. A PDR reviews preliminary design. A CDR reviews detailed design. If the discussion drifts, the review chair pulls it back. This requires a chair who understands the review objectives — not just a moderator.
These aren't revolutionary ideas. But on most programs I've seen, they're not written down anywhere. They live in someone's head, and when that person isn't in the room, the process falls apart.
A checklist and a decision log won't make your engineers smarter. But they'll make sure the smart work your engineers already did actually gets reviewed properly.
I built a Design Review Essentials toolkit that handles entry/exit criteria, action tracking, and review structure — so your team can focus on the actual engineering.
