A P3O (Portfolio, Programme, and Project Office) model is explicitly defined as the decision-enabling and delivery-support business model for all business change within an organization. Its primary purpose is to provide a structured framework that enables senior management to make informed strategic decisions about their portfolio of projects and programmes. It ensures that the right initiatives are undertaken and are delivered correctly by providing standardized processes, support, and guidance. This central model integrates governance with the delivery mechanisms for change.

A. Programme: A programme is a temporary structure designed to manage a group of related projects to deliver specific outcomes and benefits, not the overarching support model for all organizational change.

C. Project: A project is a temporary endeavor created to deliver a specific output or product. It is a component of change, not the business model that supports all change.

D. Portfolio: A portfolio is the collection of all projects and programmes an organization is undertaking to achieve its strategic objectives. The P3O model supports the management of this portfolio.
