"Very simple and well presented.

You run through a quiz that asks you to rate your company's performance in eight key areas, and then review your profile to see how you compare against the big boys.

Up until this point there isn't anything going on here that you can't do on paper – and if you've already bought a hard copy of the book you'll find a chapter at the back which allows you to do exactly that. But I can't deny that tapping on the screen with all the geeky number crunching hidden away behind a slick, colorful interface, is a much more rewarding experience than making scribbles in the back of a book. Plus the app offers a couple of extra features that are really, rather nice.

Once you've had a look at what you need to work on, the authors offer direct suggestions tailored to your profile, in five key problem areas. If that taster has whet your appetite for more, the last page of the App suggests chapter-specific reading to help improve your working practices. You can even tailor the recommendations to your role in the company, be that marketing, HR, executive leadership etc. Just rip out a chapter (digitally speaking of course, I can't imagine getting away with that in a bookshop) or buy the whole book, it's up to you.”
