Puts everything in place,
This review is from: Positioning: The Battle for Your Mind (Paperback)
This is a really great book, though figures are out of date (mid 80's) but the concepts are the same as today.
Obvious stuff in there that only makes it obvious once you've read it. Very easy to read but detailed enough to not leave you with unanswered questions.
Highly recommend to anyone really, small business, entreprenaur or just if you have a job anywhere!
Puts the commercial world nicely into perspective.
