iSpec allows you to use the most sophisticated method available - the weighted-point method.
For example you might want to evaluate the following:
|
|
|
Vendor A
|
|
Vendor B

Scores for example are from 1-10 with 10 being best. However, you can create your own custom scoring and weighted scoring reports. You can either create a separate evaluation document - which can be part of the master template with your own scoring rules contained in it and to be used during bid evaluation, or you can add scores and weights to individual headings in the various documents.
If the User may edit weighting box is checked, this means the user may change the weighting (importance) that he would like to assign to this item during tender preparation otherwise the weighting will remain as entered here during template creation.
In the above example it is clear that price is the most important issue and that 40% of the decision depends on price. Typically with this method, you would assign a percentage applicable to this item. i.e. 50 (for 50%). Thus to keep it simple your total weighting should add up to 100 - representing 100%, but this is not essential. The maximum score is the maximum number of points the vendor submission can score during evaluation. In this case the scoring scale is 1-10. However you could make it a scale of 1-5 or 1-100 for that matter.
If you leave the weighting as 0 but have a maximum score, then during scoring, iSpec will use a default weighting of 1 and multiply the score with 1 to get a weighted score.
