This is because feedback loops which are too short for the overall system makes people focus on inappropriate intermediate goals. It’s the main cause of catastrophic long term strategic mistakes. This is also why people tend to flit around from field to field. As soon as they exhaust the easy gains, they look for a learner’s high elsewhere. This feeds their addiction, but doesn’t lead to learning any useful skills. The more accurate and more rapid the loop, the more quickly you’ll arrive at the top of the hill — and the less chance you have of leaving it to climb the mountains of mastery. Process improvement happens by creating many parallel processes and discarding the ones that are unfit, not by iteratively improving a single process.
