» Every decision is a trade-off — deciding what not to do is just as important as deciding what to do

» A good product vision captures customer, user, value proposition and links to organisational objectives

» Interrogate your goals: “For this to happen, what must be true?”, then mark which are facts or assumptions

» Avoid jumping on the first idea — check what problem we think it solves, then ask, “How else could we do this?”

» Decisions should be the result of rational and deliberate reasoning, but not all are perfectly rational

» Almost every decision has associated downsides or compromises

» Avoid trying to please people or to allow individuals to dominate the decision-making process

» It’s easy to conflate transparency on the decision-making process, with transparency on the actual decisions

» Customer research and validation is critical, but it can’t always make decisions for you

» Remedy mistakes quickly and honestly to earn respect

» Use the “rule of 10” to put mistakes in context

» People remember most your small defining moments
