37. Preserve the audit trail

The contracting authority should retain approvals, communications, models, scores, conflicts and negotiations. The required output is a complete procurement record. Record the accountable owner, applicable rule, source evidence, decision criterion, approval, exception and review date [35][40].

Test the conclusion against effective competition, equal treatment, transparency, proportionality, integrity, consortium capability, financeability, service delivery, whole-life value and enforceable contract commitments. Preserve a secure audit trail from market analysis through award.

The principal risk is that later review can lack evidence of how discretion was exercised. Quantify the effect on bidder participation, price, quality, risk allocation, financing, implementation, public payments, challenge exposure and trust. Compare the proposed approach with narrower criteria, alternative packaging, staged qualification, independent assurance and a lawful stop or retender.

Translate the conclusion into tender rules, disclosure, qualification, evaluation, approvals, contract conditions and monitoring. Refresh it after material ownership, membership, financing, market or bid change.

38. Translate commitments into contract

The contracting authority should embed member roles, lock-in, guarantees, key subcontracts and remedies. The required output is a contract commitment schedule. Record the accountable owner, applicable rule, source evidence, decision criterion, approval, exception and review date [10][26].

Test the conclusion against effective competition, equal treatment, transparency, proportionality, integrity, consortium capability, financeability, service delivery, whole-life value and enforceable contract commitments. Preserve a secure audit trail from market analysis through award.

The principal risk is that winning-bid capability can disappear during mobilisation. Quantify the effect on bidder participation, price, quality, risk allocation, financing, implementation, public payments, challenge exposure and trust. Compare the proposed approach with narrower criteria, alternative packaging, staged qualification, independent assurance and a lawful stop or retender.

Translate the conclusion into tender rules, disclosure, qualification, evaluation, approvals, contract conditions and monitoring. Refresh it after material ownership, membership, financing, market or bid change.

39. Monitor post-award integrity

The contracting authority should track ownership, member changes, related parties, performance and amendments. The required output is a post-award integrity dashboard. Record the accountable owner, applicable rule, source evidence, decision criterion, approval, exception and review date [12][28].

Test the conclusion against effective competition, equal treatment, transparency, proportionality, integrity, consortium capability, financeability, service delivery, whole-life value and enforceable contract commitments. Preserve a secure audit trail from market analysis through award.

The principal risk is that risk can migrate after competitive scrutiny ends. Quantify the effect on bidder participation, price, quality, risk allocation, financing, implementation, public payments, challenge exposure and trust. Compare the proposed approach with narrower criteria, alternative packaging, staged qualification, independent assurance and a lawful stop or retender.

Translate the conclusion into tender rules, disclosure, qualification, evaluation, approvals, contract conditions and monitoring. Refresh it after material ownership, membership, financing, market or bid change.

40. Issue the procurement-integrity certificate

The contracting authority should reconcile competition, qualification, information, evaluation, award and contract controls. The required output is an auditable award certificate. Record the accountable owner, applicable rule, source evidence, decision criterion, approval, exception and review date [1][2].

Test the conclusion against effective competition, equal treatment, transparency, proportionality, integrity, consortium capability, financeability, service delivery, whole-life value and enforceable contract commitments. Preserve a secure audit trail from market analysis through award.

The principal risk is that approval can rest on disconnected reviews with inconsistent conclusions. Quantify the effect on bidder participation, price, quality, risk allocation, financing, implementation, public payments, challenge exposure and trust. Compare the proposed approach with narrower criteria, alternative packaging, staged qualification, independent assurance and a lawful stop or retender.

Translate the conclusion into tender rules, disclosure, qualification, evaluation, approvals, contract conditions and monitoring. Refresh it after material ownership, membership, financing, market or bid change.
