Speed, I am Speed. -- Lightning McQueen Some thoughts about the impact of feedback loops in startups and software. Parts: Intro Framework Observations Take-away Intro Feedback delay is the time between doing something and seeing whether it was successful. If the feedback is slow, we have a "lagging indicator". It becomes hard to link causes and effects, and in consequence it becomes hard to optimize the performance. Fast feedback makes things easy . How quickly the feedback arrives is critical. If it takes milliseconds to seconds, it works at the speed of the brain and enables a state of flow . If it takes decades to centuries, it needs a multi-generational organization like a government or organized religion to run it. Somewhere in the middle is the realm of persons, teams and companies. A framework of feedback time Here's a quick table of feedback times, in three groups, with each roughly an order of magnitude difference. C   is the level where (large) organizations ca
