How do I select a topic, which topic is selected by most students?

Depends on the mentor and how much consideration that you have already given to the topic and organisation. The topic choice is supposed to be made by you not by them but if you are undecided they may be able to give you some ideas. When you have already settled on these then they may outline the way ahead and help you formulate your milestones. Each mentor probably operates differently so there is no uniform approach and it may even vary between different students for the same mentor.

First you need to ascertain the extent of the company’s weak CSR practices and this is usually obtained from newspaper and journal articles – unless there are significant CSR issues you won’t have much to analyse and evaluate. You also need to appreciate what may come under the ‘umbrella’ of CSR, so a good understanding of what CSR entails (as there is no fixed definition) is a prerequisite.

Obviously the company statements provide some information but they will need to be held up to objective scrutiny by finding independent sources that help provide a broader perspective. Research methods are something to discuss with your mentor.
