A practical way of understanding CSI is to see how it relates to the Deming Cycle. There are a lot of similarities: both are cyclical, and they can help organizations stay aligned with the stakeholder needs, optimize services, and reduce potential errors. Also, the two methods are promoted in the ITIL CSI guidance, and they complement each other.
CSI uses a 7-step model that progresses improvements in small, achievable work packages. We'll address that topic in more depth further on, so don’t worry. The Deming Cycle, on the other hand, consists of a four-step process.
