For decades, public management was often driven by intuition, political expediency or simply "the way things have always been done". Policies were launched with great fanfare, but without the rigorous data needed to predict their success or measure their failure.
That era is ending. Today, the most effective governments and non-profits operate on a different standard: evidence-based policy making (EBPM).
In a resource-constrained environment, you cannot afford to guess. To make your mark as a modern public manager, you must be able to prove - with hard evidence - that your decisions are valid, your policies are sound and your interventions are working. The online Postgraduate Diploma in Public Management (PDPM) from the Wits School of Governance is designed to give you this exact capability, transforming you from an administrator into a strategic architect of public value.
"Evidence" in the public sector is more than just numbers on a spreadsheet; it is the currency of trust.
When a manager can back a proposal with solid data, they move from opinion to authority. Evidence-based management requires a cycle of three critical skills, all of which are central to the Wits PDPM curriculum:
Before you can solve a problem, you must understand it deeply. Evidence-based policy starts with rigorous analysis, not assumptions.
The Wits approach: The Public Policy module teaches you to interrogate the conceptual frameworks behind policy decisions. You learn to analyse the root causes of social issues and evaluate the theoretical models used to address them. This ensures that when you propose a solution, it is grounded in a deep understanding of the policy context, not just surface-level symptoms.
A great policy can fail due to poor implementation. Evidence-based managers demand real-time visibility into their operations.
The Wits approach: Through modules like the two on Strategic Public Management and Monitoring Systems and another on Public Finance and Performance-based Budgeting, you learn to design performance monitoring frameworks. You move beyond compliance reporting and merely ticking boxes to performance management. This allows you to use data to identify bottlenecks early and adapt your strategy before resources are wasted.
Did the intervention actually change lives? This is the ultimate test. A manager who can answer this question definitively is indispensable.
The Wits approach: The Evaluation and Analytical Methods modules equip you with the technical skills to interpret quantitative data and assess impact. You learn to distinguish between outputs (what you did) and outcomes (what you achieved), enabling you to report results that stand up to the scrutiny of auditors, donors, and the public.
In a sea of generalists, the specialist who speaks the language of impact is the one who gets heard.
The Wits Postgraduate Diploma in Public Management doesn’t just teach you to manage public services; it teaches you to validate them. It equips you with the analytical rigour to ensure that every mark you make on the public record counts towards a more efficient, effective and just society.
EBPM is an approach that helps people make well-informed decisions about policies, programmes and projects by putting the best available evidence from research and evaluation at the heart of policy development and implementation. It moves decision-making away from opinion and ideology towards facts and proven results.
Absolutely. Evidence-based management applies to every function. An HR manager needs data to prove that a training programme improved staff productivity. A finance manager needs performance data to justify budget allocations (performance-based budgeting). The skills of analysis and evaluation are universal tools for efficiency in managing almost any department.
The Analytical Methods module focuses on the interpretation and application of quantitative data for decision-making rather than training you to be a data scientist or coder. The goal is to make you an intelligent consumer of data - someone who can read a statistical report, understand its implications and use it to lead.
Accountability requires an "audit trail" of performance. The programme teaches you how to set up monitoring and evaluation (M&E) systems that create this trail. You learn to define clear indicators and targets upfront. This means that at the end of a project, you can transparently show exactly how resources were used and what was achieved, satisfying both internal auditors and external stakeholders.
While the PDPM is a comprehensive management qualification, the strong focuses on public policy, development and governance create a robust foundation for a career in policy analysis. If you wish to go deeper, this postgraduate diploma creates the perfect academic platform to advance to a Master’s degree, where you can pursue a dedicated research thesis on policy issues.
