The project manager needs to ensure that operational teams are responsible for running the project outputs during the step 'Transition the project into the organizational ecosystem'. This step involves integrating the project outcomes into the regular functions of the organization, ensuring that operational teams are prepared and accountable for maintaining and managing the project's outputs post-project completion.References:

In PRINCE2, a Work Package is the document where the Project Manager defines the time and cost tolerances for the work assigned to a Team Manager. The Work Package provides detailed information on the products to be delivered, the reporting requirements, and the tolerances within which the Team Manager operates.

A minimum requirement for applying the Business Case theme in PRINCE2 is to define the actions necessary to confirm that the project's benefits are realized. This involves planning how benefits will be measured and managed both during and after the project to ensure they deliver the intended value and outcomes.

The purpose of a Risk Register in PRINCE2 is to capture all the risks that may impact the project throughout its duration. It serves as a tool to document the details of each identified risk, including their nature, potential impact, and proposed responses. This register is continuously updated as new risks are identified and as existing risks evolve or are resolved.References: PRINCE2 7 Foundation handbook and official documents.

When a product cannot meet all the requirements specified in its baselined Product Description, the first action to take is to raise an off-specification. An off-specification is used in PRINCE2 to formally identify any forecasted deviation from the agreed product requirements or quality expectations.
