OK, you want a quick and "easy" read of improving the culture and productivity of your team? You could finish this book in one sitting yet do it in two so you can digest the important information.
Not needing to read cover-to-cover in that order, you may jump around and read input on attacking specific issues you have. However, you can handle this book! Written in simple straight forward terms, you can quickly apply the methods within your team. As Jack Welch states "do not sit on a decision". You can decide soon to get this done, so do it!
