Agile Manifesto was created by software delivery thought leaders in Snowbird, Utah, in 2001. It outlines 12 principles to delivering software based on four key values: working software over comprehensive documentation, customer collaboration over contract negotiation and following a plan. Agile has been adopted by domains outside of software development, including hardware systems, infrastructure, operations, and even business support to name a few. But given all the advancements in the last 20 years, is it still relevant? Or should it be treated like a historical document that has long since served its purpose?
