That's where you're very, very, wrong. A real world business is online.
Please, find me a million+ dollar business that isn't online.
I also think it's quite ironic that most IST fields are run by.. you guessed it, marketing and business majors.
Why? Because they're educated to run a company/corporation the right way. Do you really think Mark Zuckerberg makes executive decisions about facebook anymore? No way. He sits in a corner and write code like a smart person would.
A real company relies on strict deadlines and weekly, if not daily, updates to become and continue to be successful.
If you're in for a read, OSBot reminds me of this company quite a bit.
