I’ll offer a contrarian point of view.
The practical MBA curriculum may or may not be helpful to the OP if he’s getting hands on learning in operations, supply chain, managerial accounting, etc. BUT-- back in the dark ages (and with no business owners in my family) I found the theoretical work REALLY helpful. Monetary policy, labor economics, advanced techniques in market research-- none of which I’ve had to DO in my career, but all of which are really additive when you have to deal with relevant issues. Your raw materials come from China or Peru… how do you think about currency risk? There’s legislation in your state to mandate a $15/hour minimum wage- is this a good thing or a bad thing for your company (a lot of times it’s good even if you initially think it’s bad). Someone shows you focus group results which show your product is believed to be inferior to the competition… and yet your market share remains constant- why?
There are a lot of obvious tools you learn in business school and a lot of things which aren’t tools per se but are powerful ways of answering questions and dealing with ambiguity.
And the network… your classmates turned into colleagues who will end up in banking, the airline industry, ad agency, insurance, consumer products, retail, credit card, transportation… if someone is at a strong undergrad business program they may already have that…but it’s nice to know you can get a quick (and free) answer to a question from a buddy when you are stuck.
