Evaluation stages (in order):

1. Basic compliance: tender must meet the basic compliance requirements stated in the Invitation to Tender; failure renders it non-responsive.
2. Mandatory tender returnables: tender must contain all mandatory documents/information by closing; otherwise disqualified.
3. Pre-qualification criteria (if stipulated): must be met; Eskom will not measure a criterion twice across phases (no 'double dipping').
4. Functionality (if a criterion): scored against functionality criteria; must meet the minimum threshold stated in the Tender Data to proceed.
5. Financial analysis (if applicable): Eskom assesses the financial risk of the tenderer; if mitigating factors are insufficient or the risk is too high, the tenderer is not considered for award.
