Identification System
As we’ve already seen, the most difficult part of a MOC system is identifying change. It is therefore extremely important to have an effective identification system.
Most identification systems use a systematic approach. A detailed list of all hardware which is to be controlled is provided. The employee can use the list as a check-list to determine if the modification falls under any of the categories.
As each company is unique, they may have different guidelines for determining changes. It is thus extremely important to have clear, written, definitions of system boundaries and what constitutes “change”. These are generally found in the beginning of the Management of Change Policy.
- Screening process for identifying changes.

- There will also be a risk ranking system to determine the level of control the change requires. (eg. 5 approval signatures and a thorough hazard analysis vs. 1 approval signature and no formal risk assessment) Note – the risk ranking process is discussed in more detail in another section.
