What it covers
Change management is the structured work of preparing, supporting and equipping people to adopt new processes, systems or structures: understanding who is affected and how, building genuine sponsorship, redesigning roles and incentives, and sustaining the change past the initial push. Frameworks such as ADKAR and Kotter's model formalise the sequence, but the substance is behavioural, not procedural.
Why it decides whether the investment pays
Most transformation business cases assume adoption. The benefits column, faster processes, fewer errors, consolidated systems, depends entirely on people working differently, yet the cost of making that happen is usually a token percentage, negotiated down whenever the case needs to look leaner. This is where approved programmes fail: the system is live, the vendor is paid, the go-live announcement has gone out, and eighteen months later the old spreadsheets are still running underneath. Nothing dramatic went wrong. The benefits simply never arrived.
The usual distortions
Change management reduced to a communications plan, as if awareness were adoption. The workstream starting after design is finished, when the decisions that determine resistance have already been taken. And success measured by training completion rates, a metric that tracks attendance, not whether anyone works differently on a Tuesday afternoon under deadline pressure.
