I read this book over a couple of days and then went back through, working through the excercises and suggestions. There is enough information, suggestions and references to keep someone going for quite a while. The information is presented in a deceptively simply manner - breaking down essential parts of marketing into easy, stepwise exercises. I would recommend this to anyone who is running their own small/medium business or about to start up.
I've bought several other books to try and get a handle on marketing and this is by far the most comprehensive and useful.
