I recommended MMM to a friend when problems at his workplace sounded like things that came up in software design or project management. But when I reviewed the book, I found that a lot of the big-picture concepts required if not understanding, then at least familiarity with programming and/or older computer systems. It's still a good book, but I ended up feeling like he wouldn't get what I got out of it.
If we're talking about project management issues, though, I'd recommend Yourdon's "Death March" over "The Mythical Man-Month". That book has a lot more to say on how to deal with management that refuses to pick two out of "good, fast, cheap" and insists that all three are achievable.
