Note that any references made to "ITT/RFQ”, refer to the two main types of ESA procurements:
- Invitation to Tender (ITT): is a procurement approach where the intended activity is to be awarded after an open competition or competition restricted to certain nominated Tenderers. In some cases, specific programmatic requirements may result in the ITT being restricted to Tenderers from only specific Member States of the Agency.
- Request for Quotation (RFQ): is a procurement approach where the intended activity is awarded to a single nominated Tenderer.
