Change impact assessment is where most programs get the fundamentals wrong. They measure awareness and call it readiness. They map influence and call it impact analysis. They label concern as resistance and try to manage it away. This guide reframes all three: what a readiness assessment should actually tell you, how to run a stakeholder impact assessment that shapes the plan rather than sitting in a drawer, and why the resistance you are seeing is not a problem to overcome but the most valuable feedback your program will receive.
