I am looking a reseach topic related to Software Engineering or Software Process Improvement. I select a topic "Software Development Process for Small Software Companies" but Irish Software Engineering Council is already working on this topic from last one year. Therefore plz suggest me some good topic for research. I shall be very thankful to you.

Okay, we'll help you then.

"An analysis of why computer nerds get paid so much money for switching a computer off and on again."

Exactly how thankful will you be?

if you are incapable of coming up with your own topic then I would suggest you give some serious thought as to whether research is for you.
