ST p59 Renaming FSC to CS then referred to as SC
Page 58 (Change Management Process) tells us that Change Management is responsible for generating the change schedule, which is explained can be abbreviated CS (all of this sounds pretty logical. Why we had to rename FSC to CS though, I will leave to the SWAMI to predict).
But: The authors are obviously just as confused by altering the abbreviations as the common ITIL follower and continue to talk about a "SC" [p59]. After checking the overall glossary (where I could not find SC) I concluded that it should mean CS. Then I continued to find CS in the glossary, which I could also not find! It does contain change schedule, but not the abbreviation.
