This guide describes what steps usually work best when adding new features to a product. The guidelines are not mandatory; simpler features may not need any of these steps. They exist to help battle the hardest new features to add :)
The steps are not necessarily in the correct order - this is the usual order. Going back to an older step to add/change things is okay.
Goal: collect all that we can come up with for the new feature or change. Everything goes into an unorganized document (wiki page). Possible ways to organize this document is into proposal items (and proposal detail item for each proposal item).
