Where resources are acquired internally, there may be service-level agreements or terms of reference between the project, programme or portfolio and the department or function providing the resource.
Setting up the management infrastructure is called ‘mobilisation’. Projects and programmes are temporary organisations, whereas a portfolio may be permanent or semi-permanent. Therefore, while the infrastructure for managing a portfolio is mobilised once, project and programme infrastructures are mobilised and demobilised on a regular basis.

The policies and procedures to be used for acquiring and deploying resources will be set out in the resource management plan.
