The CALMS framework is used as a means of assessing whether an organization is ready to adopt DevOps processes, or how an organization is progressing in their DevOps transformation. It is based on the following five pillars:
Before silos can be torn down, there needs to be a culture of shared responsibility, or at least a group of people devoted to establishing that culture in a grassroots type of way, with management approval and support.
Similar to the technical practices centered around continuous delivery, teams undertaking a DevOps transformation should be devoted to automating as many manual tasks as possible, especially with respect to continuous integration and test automation.
Development teams are making use of lean principles to eliminate waste and optimize the value stream, such as minimizing WIP, making work visible, and reducing hand-off complexity and wait times.
The organization is devoted to collecting data on their processes, deployments, etc., in order to understand their current capabilities and where improvements could be achieved.
A culture of openness and sharing within and between teams (and enabled with the proper tools) keeps everyone working toward the same goals and eases friction with hand-offs when issues arise.
