Published award criteria (2)
- Quality: See tender pack for details
- Price: Price score per Lot
- Price carries 50 of 100 points: a 10% discount moves about 5 points. This one is won on the number: sharpen the price before polishing the prose.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
