I myself have only a CS background (BSc + MSc in CS), and I am working in IT for last 8 years. Initially, I used to have negative opinion towards people from other non-CS backgrounds able to get jobs as Software Engineers and as IT Managers/Directors.

Now for the past 5 years, I am highly appreciative of such people because each of them bring knowledge and interesting viewpoints from their respective academic/training backgrounds which serves to enrich the IT world. Thank you guys :-)
