This ranking of 100 best agile books is the average of five different rankings: the number of Amazon reviews, the number of GoodReads reviews, the average Amazon rating, the average GoodReads rating, and the number of days since first publication. That means this list shows you a mix of the most popular, best rated, and (relatively) newest books in this category.
This year I’ve decided to also show you which books dropped out of the main chart. Please take a moment to pay your respect and say goodbye to some of the best Agile oldies ever written. Their time has come.
