There are some amazing changes at the top of the list this year. Most notable is the new entry at #1 of The Lean Startup, by Eric Ries. Clearly deserved, as the whole Agile community has been talking about it all year.
But that’s not all.
Specification by Example, by Gojko Adzic, makes a spectacular jump to the 2nd slot in the list. The Scrum Field Guide, by Mitch Lacey, has skyrocketed into the list at #7. And The Culture Game, by Dan Mezick, also makes a remarkable new entry at #39.
As for the rest, I suggest you see for yourself…

LY = position last year

This list is based on quality (averate ratings) and quantity (number of ratings), both on Amazon.com and GoodReads.com. The age of the books also played a minor factor in the calculations. (Older books should keep acquiring new ratings, or else they drop in the list.)
Basically, I created four different rankings: (1) average Amazon rating, (2) number of Amazon ratings, (3) average GoodReads rating, (4) number of GoodReads ratings, (5) age of book in days since release. Then I calculated the average score of the books across these rankings (where age had only half the weight compared to the others), and then I turned this into the final ranking. The result is a list that reflects books with the most and the best ratings, weighed according to the time span in which they were able to earn those ratings.
Next week I will show you the new books that didn’t make it…
