Guidelines for supplier debriefings






  • To assist procurement practitioners handle complaints from suppliers/bidders in a fair and timely manner.
  • To improve suppliers’ understanding of the procurement process and open feedback on their bids/proposals and identify areas for improvement while encouraging their participation in future tenders.



Supplier debriefings promote a constructive and transparent dialogue between procuring authorities and suppliers. For suppliers, a debriefing provides:

  • a better understanding of the procurement process, evaluation methodology and due diligence taken by procurement practitioners during the tendering phase of the procurement cycle; and
  • an opportunity to receive open feedback on bids/proposals in order to identify areas for improvement while encouraging their participation in future tenders.

A debriefing can also be made available to successful suppliers (i.e. contractors) as a first step in establishing a sound working relationship and a precedent for a constructive feedback.

The benefits of a supplier debriefing are not, however, confined to suppliers alone. The procuring authority can also benefit in a number of ways: As mentioned above, debriefings provide an opportunity for procurement practitioners to demonstrate the procedures, evaluation methodology and due diligence taken during the tendering phase. It may also identify ways of improving the procurement process and encourage better bids from suppliers in the future.

Guidelines for supplier debriefing provide clear direction to procurement practitioners on when, where and how to conduct debriefings — as well as what can and cannot be disclosed in the process. It serves to avoid different interpretations and application of the debriefing process. Although a procuring authority may have no legal obligation to provide a debriefing, attention should be given to the value and complicity of the public procurement and the possible benefits that debriefing may produce.


Guidelines may be used as input into specialised training on supplier debriefing and specialised communications for procurement practitioners. It can also serve as a basis to review practices and ensure a continuous improvement in the process.
