A building plan can look attractive while leaving basic operational questions unresolved. Can people enter it, maintain it, evacuate it, and afford to run it? A design review creates a deliberate checkpoint for testing a proposed solution against the needs it is supposed to meet.

At NASA, life-cycle reviews use evidence to judge readiness for the next stage. The underlying question is whether enough is known about the design to justify committing more resources—not whether the presentation looks finished.

Review the design, not the presentation

Imagine a group planning a community facility. Before commissioning detailed drawings, it could bring together future users, accessibility expertise, maintenance staff, and the designers to examine the proposal. A list of unresolved interfaces—such as the relationship between event access and neighboring homes—would be more useful than a vague declaration that the design looks good.

Reviews fail when they reward polished slides or become a late surprise attack on work nobody questioned earlier. Clear criteria and timely involvement let designers prepare real evidence and revise while alternatives remain available.

A review is also a decision point: proceed, proceed subject to specified work, or reconsider. Recording the outstanding issues and their owners prevents conditional approval from being remembered later as unconditional endorsement. The value lies in exposing expensive mistakes while they are still comparatively cheap to change.
