- Data analysis (site audit) – Create a loop diagram and a document to tag each controller in the order in which they are cutover.
- Database construction
- Planning – repairs, replacements, add-ons before and during the hot cutover, schedule of one-loop-at-a-time cutover.
- Training and orientation – team members are involved in all the preceding planning and data collection operations.
- Communications – at least two different clear communication channels should be established
- Teambuilding – a well-trained group of process operators should be created
