A worked example in euro
Say a client weights Price 50, Methodology and resourcing 30 and Programme 20 for a mechanical package, and four returns come back. C is the lowest at €1,195,000, but it leaves out the commissioning, so it is excluded with that reason. That makes A, at €1,240,000, the lowest compliant sum: A takes all 50 price points, B at €1,310,000 gets 47.33 and D at €1,450,000 gets 42.76. On quality A is marked 3.5 for methodology and 3 for programme, B 4.5 and 4, and D 5 and 3.5. The totals come to 83 for A, 90.33 for B and 86.76 for D, so B ranks first, D second and A third, and C is not ranked. Had C been left in, its sum would have become the yardstick, and A would have dropped from 50 to 48.19 price points. The figures are illustrative, not from a real tender.
