Improvement plans typically introduce new processes, controls, roles, technologies, or behavioral expectations. Without structured change management, even well-designed improvements often fail due to confusion, resistance, inconsistent adoption, or lack of reinforcement. Incorporating change management activities—such as stakeholder analysis, communication planning, training, leadership sponsorship, readiness assessments, rollout sequencing, and feedback loops—increases awareness, builds understanding, and improves acceptance of the change across affected organizational units. This directly supports GRC objectives: controls must be understood and embedded into daily work to be “operating effectively,” and governance expects evidence that changes were implemented consistently, not just documented. Change management also helps manage transition risks (service disruption, control gaps, unintended consequences) and supports sustainability through reinforcement and measurement after implementation. Options A, B, and C are either incorrect or too narrow: change management does not reduce training needs (it usually includes training), it is not primarily about accounting accuracy, and while it can help M&A integration, its broad purpose in improvement plans is ensuring people adopt and maintain the new way of working—best captured by option D.
