I've been part of a very interesting discussion about software lifecycle process.

If you haven't designed a process for how your team works, then try it.

You should approach the design with a problem solving methodology that works well with collaborators and includes others in the discussion beyond your team.

It forces you to ask the questions of what do the people around you need and what is an effective way to ensure their needs are met.

Time box it and keep it simple to start with.
