ED Decision 2020/021/R
CHANGE MANAGEMENT
(a) A change can introduce new hazards and impact on the appropriateness and/or effectiveness of existing safety risk mitigation strategies. A change may be external to the organisation, or internal.
(b) A formal process for the management of change considers the following:
(1) the criticality of systems and activities;
(2) the stability of systems and operational environments; and
(3) the organisation’s past performance.
(c) System description is one of the fundamental preliminary activities in the planning of the safety management system to determine a baseline hazard analysis for the system.
As part of the formal process of the management of change, the system description and the baseline hazard analysis are reviewed periodically, even if circumstances of change are not present, to determine their continued validity.
When changes to the system are made, and periodically thereafter, the organisation responsible for the provision of AMS goes over its system and its actual operational environment in order to make sure it continues to be fully aware of the circumstances under which the provision of AMS takes place.
With regard to the management of change and safety (risk) assessments related to changes, see also ADR.OR.F.025 and GM1 ADR.OR.F.025(d).
