When did Agile begin? Some say the answer is 2001, but that date doesn't appropriately reflect history. Agile's origins — including incremental software development — can be clearly traced back to 1957. Agile has a relatively long and colorful history. Many key events occurred before, during, and after 2001.
Agile Has a Long and Colorful Heritage: A Timeline Infographic highlights key events and advancements in agile over time. A criteria for inclusion is that each entry has one or more objective and credible citation(s). This infographic references matters spanning from 1957 to 2008; it's not an exhaustive list of every possible event.
A high-resolution version of the infographic (618 KB PDF) is available here.
