This may be somewhat obvious, but I’d assume optimism biases (inside view, planning fallacy, maybe competitor neglect if it’s the kind of plan where competition is involved) play a big role in many if not most plans that don’t work out, as well as failing to bulletproof the plan initially using e.g. murphyjitsu/premortem.
A less obvious one would be aborting a project based on noisy data causing the expected value to temporarily drop; which could be prevented by predefining clear unambiguous “ejector seats”, as alkjash mentioned in their Hammertime sequence.
