This Master Class is based on P3G (Project, Programme, and Portfolio Governance)  which is principles-based thereby allowing organisations and practitioners the flexibility necessary to address their specific circumstances. The principles are grounded in logic and practice, and the guide explains both how and why they are applied. They are scalable and so are applicable from the smallest to the largest initiatives. It explains the critical importance of accountability and how to ensure consistency of decision making rights between the accountable roles. In doing so, it addresses the integration of governance at all levels in the organisation. It indicates how to establish an effective governance framework for a project, programme or entire portfolio. It is applicable to all sectors including hard infrastructure, Information and Communications Technology (ICT), and business change in both the public service and the private sector. It addresses traditional delivery methods of project governance as well as approaches such as agile and hybrid.
