The government s Infrastructure Delivery Management System comprises three core systems, namely a planning and budgeting system, a supply chain management system, and an asset management system, all of which have forward and backward linkages. These core systems are located within portfolio, program and project management processes, as well as operation and maintenance processes. Collectively these processes and systems, together with a performance management system, establish the institutional system for infrastructure delivery. The SIPDM (a component of the government s IDMS) establishes control frameworks (through a stage-gate review process) for the planning, design and execution of infrastructure projects and infrastructure procurement.
