Large system changes are absorbed by people, not projects. The delivery plan has to respect how much change a team can take at once.
Make the change manageable
- Agree on the business outcome before locking in the solution.
- Break delivery into decisions and releases that teams can absorb.
- Test with the people who will actually use and support the system.
Good delivery creates confidence as the project moves forward. Teams should understand what is changing, why it matters and what happens next.
