How to Stop Endless Discussions - RFC framework
The RFC (request for comments) process uses a document written by someone about their proposal on a topic. It has a specific timeframe and everyone can give feedback on it. The RFC and feedbacks are posted publicly. Everyone can join the discussion. The goal is to include as many people as possible to access more points of view and spread the knowledge simultaneously. The good thing is that people focus on the proposed idea and give their feedback based on facts instead of only beliefs. On the other hand, it has a way bigger effect.
The RFCs have another effect on the organization. The process seeks a consent-based environment, not a consensus-based one. If some people care about a topic a lot and come up with a written document that explains many things in detail, everyone can (and should) trust them. The authors shouldn't wait for everyone's confirmation of their proposal. When they get enough feedback, they should be able to continue further with or abandon the idea. It's their decision. Since they prepared the doc and collected many comments on it, they can have a better judgment.
