One of "Company M's" weaknesses - as I observed - with respect to manuals (and books) was that the proofing, editing, and in early times the typesetting, was done mostly by contract workers. The contract teams generally included a tech editor, usually quite capable, indexer, proofers, etc, but "Company M" absolutely refused to permit any of the team to contact the authors, except by relaying everything through "Corporate management."

The contract invariably expired before the author knew (s)he'd produced a SNAFU, and in the rare event that an author accepted a correction it never got back to the team in time to be incorporated.

Although not widely used, FUBMI was heard - F*d Up By Management Intervention - although that's almost the sole cause of the more widely used FUBAR. (Recollection is that the Hackers Dictionary defined FUBAR as "the result of applying management assistance to a SNAFU.")
