Software Failure

I’m a student of Uni of Bolton studying Computing.We are actually dealing with a course module called ‘PROFESSIONAL ISSUE’.We are been given a topic area called ‘SOFTWARE FAILURE’.All we need to do is to discuss on is, the causes of software failure and how a professional approach would reduce or eradicate software failure in the IT industry.All i need from ‘techRepublicans’ is just your views on this and suggestions.Would appreciate any help.Cheers
