Preference Points Recalculation

Independently recomputes 80/20 and 90/10 preference scores to expose award-altering errors.

📖 6 min read🎯 Intermediate✍️ Updated 2026

Why independent recalculation of preference points protects awards

Preference points under the 80/20 and 90/10 systems determine who wins, and a scoring error, whether innocent or engineered, can hand the contract to the wrong bidder and render the award irregular under the PPPFA framework. Recomputing the scores independently is the only way to confirm the award rested on correct arithmetic. AuditPro Core recalculates preference scores from source so SCM can detect errors that quietly altered the outcome.

The 80/20 and 90/10 systems

Price carries 80 or 90 points depending on the contract value bracket, with the remainder for the specific goal such as B-BBEE. Applying the wrong bracket or weighting distorts the entire result.

Where errors arise

Mistakes creep in through wrong price formulas, incorrect B-BBEE points, the wrong system for the value, or transcription errors on the scoresheet. Any one can flip the ranking.

Award-altering materiality

Only errors large enough to change the winning bidder are decisive, but they are precisely the ones that create irregular awards. Recalculation isolates the consequential mistakes from the trivial.

How AuditPro Core Bridges the Gap

  • Independent recompute: recalculates 80/20 and 90/10 scores from price and B-BBEE inputs without relying on the original scoresheet.
  • Variance flagging: highlights differences between recomputed and awarded scores, prioritising rank-changing ones.
  • Exception workflow: escalates award-altering discrepancies for SCM and legal review.
  • Traceability to source: links each recalculation to the bid price and B-BBEE certificate used.

Key Takeaways

  • Applying the wrong points system for the value bracket distorts every score.
  • Independent recomputation is the only reliable check on the scoresheet.
  • Focus on errors large enough to change the winning bidder.
  • Rank-altering scoring errors create irregular awards.
