Very relevant data for today's business world. Helps break out costs and revenues to start analyzing what is relevant or irrelevant. Also helps show tools to evaluate common reasons why costs and revenues might differ from expectations. The instructor is a very good lecturer, very engaging, easy to communicate with, seems to understand foreign accents very well. He is very active via email, office hours, and the forums. Lots of CA's to help as well. I hope all courses offered through Coursera and Illinois are like this!
