  5. Establish Change Control Procedures by which NTUA may request enhancements, customizations, interfaces, modifications or other changes to the Project by specifying the desired changes to NI Solutions. Such procedures will include the performance of an analysis by NIS and required that no change be made until a written change order describing the change was approved by the NTUA. In addition, such procedures enabled tracking of ongoing scope changes to the Project, and provided a basis for auditing scope changes to the Project. Project changes (including necessary changes, if any, to resource requirements or schedule for the corresponding Project) was documented by NIS and approved by the NTUA.

  6. Identify contractor requirements for Training were met, and to the extent requested by the NTUA, participating in the training.

  7. Emergency and Urgent assignments were resolved in a timely manner and NTUA was informed of any situations that required the NTUA to move the project ahead of schedule requiring resources on an extremely tight timeframe.

  8. Assisted in training sessions as needed describing the features and technologies being installed

  9. Coordinated all meetings to make sure the construction met the design requirements of NTUA Contracts.
