The PMES seeks to strengthen results-based management of public sector policies, programmes and projects, through improved linkages between planning, budgeting, monitoring, evaluation and reporting mechanisms. With the introduction of the PMES in all Ministries and selected portfolio Departments and Agencies since 2010, its implementation is focused on establishing and sustaining a system that meets the demand for relevant performance information required to better support the decision-making processes of Government. As such, the provision of reliable and credible information, performance accountability, and consistent building of human and technological capacities are critical to the sustainability of the PMES.
