When onboarding a large customer with a complex user base, the service provider needs to manage various interrelated projects and activities that contribute to the overall outcome. This scenario requires a coordinated approach that can handle complexity, scale, and the need for multiple outcomes.

Programme:

A programme is a group of related projects managed in a coordinated way to obtain benefits and control not available from managing them individually. In the context of onboarding a large and complex customer, a programme ensures that all projects and activities are aligned with the overall objectives, facilitating effective management of dependencies, risks, and resources.

Project:

A project typically focuses on delivering a specific output within a defined timeframe. While projects are essential components of a programme, managing the onboarding of a large, complex customer as a project alone would not address the multiple, interrelated aspects that need to be coordinated.

Emergency Change:

Emergency changes are unplanned and typically implemented to resolve a major incident or prevent a significant disruption. This is not relevant to the scenario of customer onboarding.

Normal Change:

Normal changes are pre-approved, routine changes that follow a standard process. Managing the onboarding of a large customer is far more complex than what normal change processes handle.

Conclusion: Managing the onboarding of a large customer with a complex user base should be done as a programme, which allows for coordinated management of multiple related projects and activities to achieve the overall strategic goals.
