When it comes to your decisions and your data, one tool I like to use is called a Decision Log.
By recording your important or ambiguous decisions in this format – the game changers, the ones where your decision-makers disagree, the ones where it’s not so clear what the best decision is or what the influencing factors might be – you provide for yourself a means of auditing, reflecting on, and redirecting yourself towards your goals by getting really clear on how you’re using data, both in the moment of decision-making and as part of post-process analysis.
This can be particularly useful for times when the result of your decision was unexpected, you want to repeat results, or you want to better understand the context in which you’re working.
