This business book can be firmly placed in the "useful" category. We are shown the different phases of business growth and decline and McKeown unwraps for us what is required to stay at the peak "Predictable Success". Essentially, Predictable Success is a fine balance between systems to keep the business efficient, ensure compliance, etc. and the right people to shake things up and keep injecting creativity into the company. McKeown is decidedly more detailed than this - avoiding cheesy acronyms, he clearly pinpoints the elements that are required, both in systems and in your people, to keep things at the peak. This will be a useful book to have on the shelf and read at least a couple of times to keep in focus all the elements that need to be managed. A highly practical book that doesn't oversimplify.
