Once upon a time 2 really smart guys came up with a simple framework for teams who knew what they were doing to build products. It worked well. Other people who knew what they were doing started doing it. Then those that didn’t know what they were doing started doing it figuring they’d now know what they were doing as well.
It became popular because for the cost of a 2 day course you could get certified in that you knew what you were doing.
The framework was promoted as being the same as Agile, when it wasn’t. Companies that wanted to go Agile wanted folks who knew what they were doing so started hiring these master. This had the framework start to be used everywhere, even where it was not designed for. And, with its success, it became closed to new ideas by allowing new things to be put into the framework, but never allowing a challenge to the foundations of the framework
Then another group decided that they could take this framework and wrap it with their own. Now they had a big framework for all companies. And they put Agile in its name because no one knows what Agile is anyway
So now we have all of these people doing something called Agile that isn’t.
The moral of the story? A framework won’t help you become Agile. Focusing on your work may.
