GTAC’s work focuses on four key activities:

1. Improved data and evidence for decision-making – through access to reliable data and evidence, public sector decision-makers can make more informed decisions around policies and operations.
2. Enhanced institutional capability – through improved internal processes public institutions are able to operate more effectively and deliver services more efficiently.
3. Better capital investment decisions – GTAC’s appraisals and advice lead to more strategic and sound capital investment decisions optimising infrastructure and project spending.

This in turn leads to broader benefits including:

• Strengthened and high-performing public institutions
• Increased infrastructure development

Which ultimately contributes to the creation of a capable, ethical and developmental state characterised by strong and accountable institutions that contribute to sustainable socio-economic development and improved service delivery that creates a more inclusive and prosperous South Africa.

A hub-based model is particularly effective in the public sector, where cross-functional
expertise is critical to achieving outcomes.

By grouping similar functions – such as advisory and programme management services – into dedicated hubs, GTAC can optimise resource allocation and streamline processes. This eliminates duplication of effort and reduces inefficiencies.

Another benefit of the new structure is greater collaboration. Collaboration across hubs encourages a more coordinated response to public sector needs, ensuring alignment and common goals while recognising the unique service offerings of each unit. The hub structure also creates a critical mass of expertise so that the hubs become centres of excellence capable of managing larger and more complex projects.
