ONERA's procurement processes can be broken down as follows :
- Specification of needs: technical requirements, performance or results indicators
- Calling for tenders, selecting candidates based on their technical skills and know-how, as well as their financial health and compliance with tax and social security obligations
- Selecting suppliers according to clear criteria defined in the call for tenders
- Putting in place written contracts signed prior to service provision and defining the the parties' reciprocal obligations
ONERA ensures that its suppliers respect the terms of the contracts and the confidentiality of information about their know-how and their own techniques.
