Which activity is NOT recommended by the 'start where you are' guiding principle?

The ‘start where you are’ guiding principle advises organizations to observe and understand the current state of affairs before initiating any improvement or change1. This principle also recommends using source data, involving people who know the service, and applying risk management when considering new processes2. However, this principle does not suggest discarding existing processes before assessing their usefulness, as this would be wasteful and potentially harmful3. References: ITIL Foundation - ITIL 4 Edition, page 7; ITIL® 4 – A Pocket Guide, page 26; ITIL® 4 Practice Guide: Start Where You Are, page 9.
