Decide faster on reversible things, slower on permanent ones
Founders often apply uniform deliberation to every decision, which means small reversible choices consume the attention that irreversible ones deserve. Sort decisions by cost of reversal. A creative direction, a pricing test, a new content format or a tooling choice can be tried and undone cheaply — decide in an afternoon and learn from the outcome. A cofounder agreement, a category position, a large hire or a long lease is expensive to undo — take weeks, seek disconfirming evidence and talk to people who have made the same choice. Applying this single filter usually increases a company's speed and reduces its serious mistakes at the same time, because the deliberation gets moved to where it actually changes the expected outcome.
