Making big changes to your development process creates chaos. I advise customers to start small and run a pilot team “process experiment” to understand the risks and challenges of the big change. In addition, the prototype or experiment helps the organization understand how the change affects day-to-day activities and management roles.
At the end of the timeboxed experiment, we collect the evidence and determine if and how to roll out the change to all the teams. To make big changes, reduce risk by exposing issues and creating some evidence-based support for the change.
