Agile transformation is hard because cultural change is hard. It’s not one problem that needs to be solved, but a series of hundreds decisions affecting lots of people over a long period of time that affects relationships, processes, and even the state of mind of those working within the change.  Disciplined Agile (DA) is unlike any other framework, because it’s based on empiricism, industry data and adoption of proven practices. The result is a huge wealth of structured information that allows you to map your challenges into a tree structure of proven strategies that other people have found to work in practice. In effect you can apply the DA framework to identify process improvements that reflect the actual situations faced by your teams.
