You are absolutely right.
I have been battling this topic the last two weeks, to the point where I was thinking I cannot possibly do this masters, and then concluded I need to change my topic to one where I know what questions to ask!
My previous MA was in Classics, more than 10 years ago, and highly philosophical, after all, my sources were all centuries old, and anything new and exciting were interpretations.
I only started back in August, and not going to start writing my dissertation for a year, but we got coursework two weeks ago to introduce our topic over a 3 page write up. I did not feel ready for that yet.
But I am studying distance learning (blended? Online and workshops) with my old university in Norway, so have limited access to libraries and resources. There an MBA is supposed to offer new insights, and seems much more research based. I have to study something current, and of general interest, which provides new knowledge.
My modules now are Organizational Theory, and Research Method. I am just two weeks into the modules.
So, I changed my topic.
If I cant figure out where my starting point is, then I am doing the wrong topic.
I will study to what degree cyber-crime is driving forward changes in how organizations communicate and collaborate.
At least, cyber crime, internet and email security is "my area" and if I can put my own field into a dissertation, the outcome will be so much better. I know where to find my resources, and I know the area well enough to try find a good starting point. I will narrow it down more as I go along.
