The Hidden Cost of Slow Feedback Loops

Fast feedback loops are the hidden engine of delivery speed. The author shows that every extra minute spent waiting for verification in staging or production eats away at a team's capacity, eventually costing the equivalent of one engineer per week. By comparing local, staging, and production verification steps, the piece makes clear why engineers should demand a local feedback path and how the absence of it inflates lead time and reduces velocity.

The article walks through a concrete scenario: an 8-engineer team that adds ten minutes of extra verification per run, six runs a day, loses eight hours daily - effectively one full-time engineer. It then links this loss to slower velocity, higher lead time, and growing technical debt as teams defer fixing the feedback loop.

Practical advice follows: treat verification time as a first-class metric, invest early in local test harnesses, and avoid the "deploy to test" shortcut. The author cites a real case where building a local setup reduced verification from 20-30 minutes to under a minute, instantly freeing capacity for new work. The core takeaway is that speeding up feedback is not a nice-to-have; it's a capacity-preserving investment.

Technical leaders can use this insight to audit their own pipelines, set concrete targets for local verification time, and prioritize tooling that isolates dependencies. The result is a healthier feedback loop, steadier velocity, and a team that spends more time building features than waiting for them to run.
