Running Effective Architecture Reviews as a PM

Architecture reviews are one of the highest-leverage activities a PM can participate in. A thirty-minute review that catches a bad design decision saves weeks of rework later. But most PMs either skip them or sit silently while engineers talk to each other.

My Role in the Room

I am not there to evaluate the technical merits of choosing PostgreSQL over MongoDB. That is the engineering lead's job. I am there to ask questions that engineers sometimes forget to ask themselves. How does this design handle failure? What happens when the third-party API is down? How do we roll this back if something goes wrong? What are the performance implications at twice our current load?

These questions come from a delivery perspective. I have seen enough production incidents to know which architectural shortcuts create pain later.

The Format That Works

I use a structured template. The presenting engineer covers four sections: what we are building, why we chose this approach, what alternatives we considered, and what risks we see. Each section gets five minutes. Then ten minutes for questions. The whole thing fits in thirty minutes.

The key constraint is that every review must produce a decision. Not "let us think about it." Either we approve the approach, approve with conditions, or send it back for revision. Indecision in architecture reviews is how projects drift.

What I Document

After every review, I capture three things: the decision made, the key tradeoffs accepted, and any follow-up items with owners and due dates. This document becomes invaluable during incident reviews when someone asks "why did we build it this way."

The Impact

Since implementing structured architecture reviews, our production incident rate for design-related issues dropped noticeably. More importantly, engineers started thinking about failure modes during design instead of discovering them during outages. That shift in engineering culture is the real win.
