  • Prepare business case inputs, affordability assessments, governance papers, and board-level decision materials.
  • Support contract mobilisation and service commencement activities, including obligations tracking, governance establishment, and implementation of ongoing commercial management processes.
  • Establish the commercial management framework required to govern supplier performance post-transition.
