That book is an incredible read for anyone, even just the first couple chapters, but the central thesis is "you probably cannot pay any amount of money to make an over-due software development (or many other kinds of development) project be an on-time project", and not "there is no point in growing a team to solve bigger problems faster". You can't hire another orchestra to help play the same song faster, but you can hire another orchestra for more music over a longer time.
