When should PRINCE2 Agile be used?

PRINCE2 Agile is a project management method designed for projects, which are temporary undertakings to create a specific product or result. It is not intended for ongoing, business-as-usual (BAU) activities such as service delivery or routine maintenance. The scenario of creating a team to deliver a specific product perfectly describes a project, which is the correct context for applying PRINCE2 Agile.

B. Delivering an ongoing service is a continuous operational activity (BAU), not a project with a defined start and end.
C. Product maintenance by an established team is typically considered an ongoing operational task (BAU), not a temporary project structure.
D. Implementing simple update requests is usually handled as part of ongoing operations or a minor change process, not a formal project.
