  • facilitate adequate dissemination of the project’s results to reach the desired strategic impact
  • ensure the communication between partners and the co-ordination of actions
  • communicate activity progress by reporting and issuing of deliverables and milestones
  • inform the ITD work area leader of progress made
  • ensure the best use of the project resources
  • manage the relationship with the ITD work area leader to ensure the appropriate delivery of engineering data to support the development of the work packages
  • optimise the full capability of the project team
