This picture was developed in 2006 to explain to a group of children’s rights advocacy NPOs and lawyers the importance of costing policy proposals as a key strategy in persuading government to take the policies on board and finance them in the budget. The green block describes where we see ourselves within the process of advocating for the interests of children and other vulnerable groups.

Cornerstone has subsequently used this picture as an introductory slide in our training courses on policy costing.


Cornerstone uses this picture in our presentations of costing policy to emphasise that anyone who can do simple multiplication can do costing, because it simply involves using this equation to estimate total progamme costs – like working out a budget for a party.

We note that this equation is used in many different forms to estimate the cost of the many layers and types of activities that make up a government programme.


This picture illustrates the processes and roles that are typically involved in a policy costing project.

This picture illustrates the typical policy development process and highlights the different types of cost analysis that should ideally inform each step in the process. The main point of the picture was to highlight that cost effectiveness analysis of implementation options often reveals information that needs to be feedback (big red arrow) into strategic planning.

When embarking on a policy costing project the first step is to gain a thorough understanding of the institutions and activities involved in the delivering the policy. We find that it is useful, possibly even essential, to draw a process model / map of the programme to be costed. The act of drawing such a model tests ones understanding of the activities involved and the relationships between service demand, processes and inputs.
This picture shows the first process model / map we developed in 1999. It shows the different stages in the child justice system that the Child Justice Bill proposed putting in place. This process model underpins the structure of the child justice bill costing model.

This picture shows the institutional arrangements in South Africa for managing sexual assault and rape cases. This picture underpins the structure of the costing model of the Thuthuzela system.

This picture shows the structure of the costing model that Cornerstone developed to cost the nutrition services and interventions for children up to five years old in South Africa. This picture highlights the linkages across the sheets in the costing model, which hopefully makes it easier to follow the logic of the methodology.
