Notas do Editor
- Where there is ‘integration’ of systems within government the most prevalent form through the exchange of batch files. There are very very few instances of more sophisticated integration. [go through points] Looking at the current situation it becomes clear that at present Government’s IT infrastructure and thinking simply does not reflect the everyday necessity for the exchange of information or the integration of business processes across agencies
- As reiterated by the Deputy-President’s comments, technology has critical enabling role to play in helping the poorest of the poor, but in this case, it is proving to be more of a barrier than anything else as it is simply reinforcing the rigid, siloed nature of government functions. One cannot look at government functions within departments in isolation when striving to help citizens and deliver quality services. You need to consider the end-to-end processes e.g. SASSA grant application processing might take 3 days, but gathering evidence stakes 2 years This is a simple example, but there are literally hundreds of processes impacting all areas of Government where the disconnected of Government affects the everyday lives of citizens, for instance: Processing of court cases Processing of adoption cases Registration and compliance of companies and individuals in economic activity imposing unnecessary costs to doing business
- Departmental planning still in silo’s – lead to duplications Multiple, Fragmented Departmental Plans and Systems Regulation does not prescribe “cluster business plans” it is extremely difficult to “plan/develop cluster/transversal systems” Common/Transversal systems planning requires interdepartmental co-operation and strong lead department and funding model to succeed.
- Mathematical definition is just an elegant way of writing 1+1= 2
