For many newcomers Agile, the new kid on the block, started in 2001 when the manifesto for agile software development was published. While it is true that the manifesto had a significant contribution, there is a history of 'out f the box' thinking that's is good to be know, to learn from the past mistakes and achieve the ultimate goal of the Agile Enterprise: responding fast to market changes in an efficient and effective manner. I believe that it is time that Lean and Six Sigma, merged in a a single discipline at the same time as the publication of the manifesto, joins Agile becoming the foundation of modern products and services delivery frameworks.
I believe that a combined history of Agile, Lean and Six Sigma is more than a lessons learned exercise, it is a recognition of the contribution of previous generations Instead of demonising everything that was done before 2001 we should retain the knowledge and learn from their mistakes but also from their achievements.
