OBS_VALUE: Before choosing the procurement process, all suppliers must get fair notice of the contract opportunity. The process must encourage competition and suppliers must have enough time to respond. In case of an abnormally low bid, the agency must verify that the supplier is capable of satisfying all of the conditions for participation and of delivering all of the contract requirements (quality, quantity, time and location). Due diligence to verify financial soundness of suppliers should also be conducted before the award of a contract (Rule 46). Unsuccessful suppliers must be promptly informed in writing and be debriefed of the reasons for the unsuccessful proposal (Rules 47 and 49). Rule 50 provides for suppliers submitting their complaints to the competent authority as well as having further redress for an independent review; mediation or alternative dispute resolution; an investigation by the Auditor-General/Ombudsman/State Services Commission/Commerce Commission or hearing before the Court.
