Which two procurement procedures in the EU do not involve negotiation?

The open procedure and the restricted procedure are two procurement methods that do not involve negotiation, making the choice involving these two procedures the correct answer.

In the open procedure, any supplier can respond to the tender, which is generally characterized by a straightforward and clear bidding process. Suppliers submit bids based solely on the criteria outlined in the tender documents without the opportunity for negotiation. This method promotes transparency and equal treatment among all bidders.

The restricted procedure also does not incorporate negotiation. In this method, suppliers must first submit applications to be selected for the bidding phase, which means that only those meeting specific qualification criteria advance. Once selected, the bidding process follows a similar non-negotiable format where the suppliers must adhere strictly to the terms outlined in the initial request for bids.

On the other hand, the competitive procedure allows for negotiation after the initial submission of tenders, and the competitive dialogue process involves discussions with potential suppliers, both of which introduce elements of negotiation that are not applicable in the open and restricted procedures.
