A characteristic that distinguishes a project from regular business operations is that it introduces business change. Projects are temporary endeavors undertaken to create a unique product, service, or result, and they often drive significant changes within an organization, unlike regular operations, which are repetitive and ongoing.

The Managing a Stage Boundary process provides the Project Board with information necessary to review the success of the current stage and decide whether there remains a justified business reason to continue with the project. This process includes the evaluation of the stage's performance and the ongoing viability of the project. References: PRINCE2 Foundation Training Manual; PRINCE2 2017 Foundation handbook.

A product breakdown structure (PBS) in PRINCE2is a hierarchical decomposition of the major products that are to be developed in a project. It helps in visualizing all the products (deliverables) that are required for the project, ensuring that all products are identified and nothing is overlooked. The PBS does not indicate the order of product creation, resource requirements, or control points, but strictly the products needed.

In PRINCE2, an 'outcome' is defined as the result achieved by the project after implementing changes through its activities. Outcomes are the new states enabled by the project's outputs, differing from benefits in that they are not necessarily quantified as improvements until later evaluated as such.References: PRINCE27 Foundation documentation on project outputs, outcomes, and benefits.

This statement is not true as the purpose of the Initiating a Project process. The correct purpose of this process is to ensure that there are solid foundations for the project, usually after the project has already been decided as worthwhile and approved for initiation. The decision to initiate a project is typically made before the Initiating a Project process. References: PRINCE2Foundation official documentation and study materials.
