We have developed an even easier method of evaluating the books, a quick visual we call The Cocktail Party Index (CPI). Instead of simply giving a book a thumbs up or down, or perhaps the overdone star rating, we’ve devised a more amusing and in-depth analysis.
On the X axis we measure a book’s overall quality including:
Each book is given one of five drink rankings including:
As an example, Groundswell was a team favorite and all three team members gave it the illustrious Martini rating. Think of this as the four star or two thumbs up rating.
On the Y axis we chart a book’s overall utility including:
Here again we focus on a five point scale:
Going back to our Groundswell example, we all gave it a 5. A Martini-5 to be exact. not only did we find the book extremely relevant, engaging, and chalk full of incredible information, we thought the book’s case studies, detailed action items, stats, and read level was incredible. Five years later, it’s still a great read on all things Web 2.0.
Another example is Black Swan. While the group gave it a Martini level rating because of the incredible abound of information and relevance, it was extremely difficult to read, for what we do, we didn’t find it that useful, and there were really no action items to take from the book and apply to our real life careers. Overal it got a Martini-2.
