What is management of change in process safety?

Management of Change (MOC) is a critical business activity whereby failure to manage change effectively within an organisation can lead to catastrophic consequences. All change no matter how small the change may seem, even if of a temporary nature, can create unforeseen and sometimes unacceptable side effects. All changes, therefore, have to be studied with a holistic systematic approach such that these side effects can be identified, and any resulting risk mitigated appropriately.
