The cost of a slow feedback loop
How long it takes to learn whether something worked shapes everything. Slow loops don't just delay learning — they degrade it.
The feedback loop — the time between doing something and learning whether it worked — is one of the most underrated factors in how fast a team improves. Short loops compound learning quickly. Long loops don't just slow you down; they make each lesson worse.
Delay degrades the lesson
When feedback is slow, you've moved on by the time it arrives, the context is cold, and you're often guessing which of many changes caused the result. A fast loop ties cause to effect tightly — you remember exactly what you did and can connect it to the outcome.
Shorten the loop deliberately
Almost any process improves when you shorten its feedback loop: ship smaller so you learn sooner, measure closer to the action, automate the checks so results come back in minutes not weeks. Speed of learning often matters more than speed of doing.
It's not just how fast you work. It's how fast you find out whether the work worked.
