Earlier quoted context omitted.
My favorite Agile-ism is when Agile is defined as “the process that works for the team”. If a team adopts agile (in any variation) and doesn’t like it, the Agile defenders will appear and argue that the team wasn’t actually doing agile. Agile is defined as the process that works, so if it didn’t work it couldn’t have been agile. If only you read The Agile Manifesto you would understand!
My definition of agile is that process is a knob that you can turn. You don't like how the process is working out for your team? Adjust the process. Find the sweet spot for your team. As your team changes size and/or members, keep adjusting. "We're going to do agile by following this rigid process" is an oxymoron.
The real claim of the agile industry is that they know what can work and that you can find it using agile. That also has real value - if true.
