What is Organizational Change Management (OCM)?
OCM prepares people to adopt what projects deliver: stakeholder readiness, communication, training, champions, resistance management, and reinforcement until the new way sticks. It's distinct from project change control (which governs baselines) — same words, different universe, and exams test the difference.
The evidence is blunt: capability without adoption delivers nothing, and adoption is engineered, not announced. Budgets that include OCM look expensive until compared with systems nobody uses.
Worked example
A distributor's new routing system is technically flawless and universally resented — drivers weren't consulted, dispatchers fear it, and month one sees mass manual overrides. The rescue is pure OCM: driver councils shape the next release, the best dispatcher becomes the trainer, overrides get reviewed weekly not banned. Adoption hits 90% by month four. The code never changed; the change management did.
