I've been promoted in my company's IT department, we have 3 developers, a DBA and a Sys Admin. and one of the first major projects I want to tackle is updating how we manage our department's Documentation. Basically, it can stand to be a lot more organized. Each member has some documents they manage for the job, but basically there is a lot of "one hand doesn't know what the other is doing". In addition, there are a lot of incomplete and/or outdated documents spread across a number of directories in our shared network drive. New technology is not well documented, etc.
So a few questions I have is:
Is there any specific software that's recommended for centralizing documentation? For example, I have heard some people use Media Wiki.
Any advice on an organizational structure for documentation?
Best practices for dev team documentation?
Worth mentioning that our company is a .NET shop.
(Also, If these questions seemed open ended, or not constructive, I apologize. I'm happy to get any personal accounts, but even just a few quick tips based on your experience, would be really helpful.)
