Depends. On you career goals, and the current management perception of what training & knowledge someone needs.
I got the Master's in Engineering, but never wanted to get the MBA. Even though all my engineer friends who did the MBA said it was a cakewalk compared to Engineering. Would an MBA have been useful? Not really, at least on the path that my career took over the years.
What I DID do, though, was collect some sort of bogus certificate by taking a series of casual classes in business subjects. Six weeks each, two nights a week. And the subjects I took were Accounting for non-Financial Managers I & II, Financial Analysis I & II, Purchasing Management, Marketing, and...umm...something else that obviously didn't make a mental impact.
I have stayed generally in the Engineering side of things, but now I can discuss company finances at a higher level with the CFO & CEO, do business planning, budgeting, understand Bean Counter Lunacy and the subsequent company decisions that are made because of it, and have the ability to argue my case in their language.
And now I laugh even harder at those folks that are in Marketing because I know how they are trained.
