It's really not all that complicated. The only process that really has a lot of discussion is when people have disagreements and are trying to come up with a sane way that allows everyone to get to the best content possible. Only in those situations doesn't anyone ever refer to the guidelines or processes for handling issues between people.
The few exceptions are when we as a community feel there is a gray area left to interpretation because the action is large enough to possibly effect a good number of editors. We hold a discussion in those cases. This happens more often than not around page deletions, page merges, category deletions, category merging, tag merging, cross included template changes that effect a large number of pages, changes in process, and other huge things.
There isn't any extra processes and bureaucracy on wikipedia then there has to be or then the community feels is necessary.
