Agile is a mindset. It comes with certain behaviour and a certain culture. As with many things most people and organisations have to go through some serious change before they can actually be successful within an Agile setting. Change is hard, and it takes time. I strongly believe that it helps when you simply understand what you're trying to achieve.
'Agile' is no buzzword or a complex management theory, it's natural behaviour for millions of people; It's not for managers. It's for everyone and it's easy to understand as long as you acknowledge that 'being Agile' has nothing to do with the process you follow or the tools you use. 'Being Agile' is about culture, behaviour and mindset.
This post intends to reword the Agile Manifesto in a way that makes its meaning obvious. Understanding something, doesn't mean you're immediately capable of doing it, but it's a very good first step and it will help you on your way.
