This looks like a thoroughly useful product. I love the fact that it basically tells you what the most important thing you should work on to improve customer happiness is!

If you have lots of customers making lots of noise about lots of different issues it's going to be very hard to prioritise which of the various and apparently equally important squeaky wheels should get the grease (ie. your limited time) and this looks to me as though it would be an invaluable asset in helping make those types of decisions.
