When is Competitive Dialogue Used?
Competitive Dialogue applies to complex projects where technical solutions need development through discussion between contracting authority and selected bidders.
What are Negotiated Procedures?
Negotiated Procedures allow direct negotiation with suppliers, but only in specific limited circumstances defined by EU law.
