Using the Pega Express delivery approach, governance is established during the prepare phase of the project. The prepare phase involves setting up the project team, roles, responsibilities, tools, processes, and standards that will guide the project delivery. Governance ensures that the project is aligned with the business objectives, follows best practices, meets quality criteria, and delivers value to the stakeholders.
