Ibm innovate adoption of continuous delivery at scale at a large telco - practical maturity model
2 likes1,258 views
The document presents a maturity model for adopting continuous delivery at a large telecommunications company. It outlines various technical capabilities required for continuous delivery, arranged in a dependency tree showing the foundational capabilities required first. These capabilities include features like automated unit testing, configuration management, and deployment practices. The model is intended to help teams progressively improve processes and achieve continuous delivery over multiple years by establishing these foundation capabilities. It also provides definitions and metrics for measuring progress for each capability.

- 4. Why we needed yet another maturity model 3 • Maturity Models are usually really high level – we wanted to enable teams to go on the journey themselves • Maturity models usually don’t really tell you about dependencies, which we wanted to address to avoid “we do CI, but don’t have automated tests” • Maturity models usually don’t tell when you need to coordinate something centrally and what applications can do on their own • We didn’t like that the models had reportable levels, we wanted to see progress not gaining levels
