My goodness....you ARE fortunate. I could only dream of something like that.

But to reiterate back to the posted subject, IMO it is not a stability issue. Other than viewing management as being ruthlessly stable about insisting on standards being maintained by ALL possible authors of documentation.

Freedom (in this case, the freedom represented by the ability of multiple authors having the freedom to alter documents on thei own) is only a good thing if those with it also accept and apply responsibility.

To put it more bluntly, authors can only have freedom to do what they want with CONTENT, if they also accept and comply with PROCESS.
