Once your project has been retained by the EC, the details of the Grant Agreement (GA) have to be negotiated. This Negotiation process is largely the same for all projects and encompasses two parts:
a) an adaptation of scientific/technical content of your proposal based on the Evaluation Summary Report
The administrative and financial aspects of the GA will be dealt with in the Grant Preparation Forms (GPF) in the online tool NEF (short for 'Negotiation Forms').
Please note that any decision regarding the budget is exclusively made by the Commission. What is negotiable, however, are the timing, form and content of the deliverables, the reporting periods, and related aspects of your project as set down in the Description of Work (formerly Part B of your proposal which now becomes Annex I of the GA).
People: Please find more information about the mandatory documents required depending the Marie Curie Action.
