Let's say you need to choose some technology for your project, or you already have problems with some technologies, so you want to replace them with others. If you do not maintain a decision log, you have a high risk of making bad decisions that are biased, based on authority, and take too long.
I can’t say what their corporate culture is like now, but they’ve had a pretty poor reputation in the past, including the notion that the lowest performing 10% should be fired every year. The Amazon folks I’ve known have been great people - not at all the Gordon Gecko types you’d imagine from that - but culture in large corporations varies a lot by the team you’re in.
I came up with a saying back in the 90s when I was doing the startup scene - “Do you want it right, or by Tuesday?” Sometimes they do indeed need it by Tuesday. More of the time they have no idea why you need the extra days to get it right. But it’s really important for those in a leadership position - whether they’re managers or senior engineers - to push back and set expectations.
