This stage translates the strategic and legal groundwork from Stage II into the operational preparation of the tender documentation once the funding has been secured and the project proposal approved and/or granted. Procurers establish the administrative and technical tender teams, define legal and procedural structures, and develop detailed technical specifications and evaluation frameworks. The process culminates in a complete, transparent, and compliant tender package, ready for publication, ensuring clarity, fairness, and competitiveness. Innovator providers gain understanding on the instrument and participate in the market interaction done by the procurers (i.e. OMC) and perform the necessary preparation work to apply to the tender.
