Let's say a large enterprise opens a new office in (insert random location here) and want the new colleagues up to speed as fast as possible. Let's also say this enterprise is a very typical one with a complex environment, lots of history and almost full lack of documentation.
What's already been decided is that the new colleagues will receive howto-style documentation for the most typical tasks and will get seme architecture documentation for some of the more complicated systems.
Any ideas about improving this process? And more specifically, what should such a howto document look like to be helpful?
