When we need to make decisions we may schedule a meeting, or start some POC or just lead by example. We’ll need to properly explain our idea, present pros and cons and communicate it well to all interested parties. A process we’ve been using for this is to create a decision log document.
This is similar in concept to a RFC but the semantics are different. While on a RFC the focus is on how we’re doing something and specific details, the decision log is all about presenting ideas and reach an outcome.
