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.
Exactly! I see how a mindset “we delivered (shit) quickly” successfully reproduces itself, over and over in a lot of companies.
I think the actual reason is that business want to make money on promises right here right now. Business promises a lot of features to investors give money, and then business implement a lot of (shit) features. And then they continue kinda “okay, features broken, give us more money and we will fix it”.
