Competitive bidding is most appropriate when there is asufficient number of capable suppliersto create genuine competition and whenadequate timeis available to conduct the process fairly and transparently. These conditions allow suppliers to prepare robust bids and enable buyers to evaluate proposals properly. Competitive bidding is less suitable where specifications are unstable or urgent decisions are required. Ethical and responsible sourcing emphasises proportionality and fairness, ensuring competition is used where it adds value and does not compromise delivery, governance, or stakeholder needs.
