AMC1 21.A.239(c)(4)(ii) Design management system ED Decision 2022/021/R MANAGEMENT OF CHANGE This AMC provides a means to consider organisational changes for their potential impact on safety. Organisational changes should also be evaluated for their significance, as required by point [21.A.247](#_DxCrossRefBm1649096950). In addition, necessary changes should be introduced into the handbook, as per point [21.A.243](#_DxCrossRefBm1649097316)(c). The design management system should be designed such that all the above points are taken into account. (a)     Organisational changes should be proactively considered for their safety implications. The magnitude of a change, its safety criticality, and its potential impact on human performance (HP) should be assessed in any process for the management of change. Certain non-complex organisational changes may not require additional assessment. (b)     Special consideration, including human factors (HF) issues, should be given to the transition period during which the change becomes effective. (c)      During the process for the management of change, relevant previous risk assessments and existing hazards should be reviewed for their possible effects. ##### AMC1 21.A.239(c)(4)(ii) Design management system *ED Decision 2022/021/R* **MANAGEMENT OF CHANGE** This AMC provides a means to consider organisational changes for their potential impact on safety.
