Developer experience surveys
Regular short surveys that ask engineers what slows them down. They catch problems system data misses. They are not a substitute for DORA, and DORA is not a substitute for them.
Why it matters to an engineering manager
Surveys catch waits that Git cannot see: flaky tests, unclear requirements, a review process nobody will say out loud in a metrics tool.
Which tools measure this
Tools tagged DevEx surveys. A tag means the vendor's pages listed it. It does not mean every sub-metric is broken out.
