What should I do my IA on?

I would suggest writing your business internal assignment project on a company that is A) very familiar and local i.e. you can easily contact them and ask for primary data; B) well-known and speculated by the media so that secundary data is accessible; C) ideally a company that would be speculated by the media but that you still could contact to create a mixture of primary and secundary data. Once you find a firm you're interested in, you should formulate a research question. This question should be a yes-no question that can be answerable through a series of analysis with about 4 different business tools.
