Impact Assessment is the process of analysing how a change will affect people, processes, and systems. It helps answer practical questions such as who is impacted, what is changing for them, and how significant that change is. This insight is critical for planning communication, training, and support. A good impact assessment goes beyond surface-level analysis and looks at real day-to-day changes in how people work. It provides the foundation for effective change management by ensuring efforts are targeted where they are needed most.
