ERP, Application Software - suggestions on the topic for phd in software engineering

hi friends, im trying to get enrolled into a phd programme in the field of S.E.,but i have a fewtopics in my mind which create a great confusion for me....as in which one would be the best for research....topics r:ERP,

Application Software,
MultiTasking,
Beta testing or
SDLC.plllllssssss help.

These are very broad topics. It is important for you to read at least 10 articles that were written in the past 5 years. If you do that, you will see what recent research efforts have been made.

It is too broad to say you will focus on Beta testing or multitasking. Combine a few topics, or write with a focus on a particular kind of software. Most importantly, read some recent articles. If you already have read many recent articles, please describe to me the one that is your favorite.

I want to know what your interests are and what kinds of research designs you are familiar with.

If you just want suggestions for topics, simply google this:
