In the CITI Change Diamond™, “Realisation” focuses on ensuring that the intended benefits of change are achieved, measured, and sustained over time. It brings together benefits management, performance measurement, continuous improvement, and organisational learning to confirm that change is delivering the expected value. By tracking outcomes against objectives and embedding lessons learned into future initiatives, Realisation helps organisations maximise return on investment, reinforce successful behaviours, and ensure that change delivers lasting strategic and operational benefits.
