This page explains how oboloo turns the 0–5 scores you give each criterion into a supplier's Score (%). It applies to internal and self-assessment scorecards on the Scorecards, Performance, Risk and Sustainability tabs. To build a scorecard, see Create a Supplier Scorecard.
How a scorecard is structured
Part | What it is | Set when |
Category/Area | A group of related criteria, such as Performance or Cost Effectiveness. Each area has a Weighting (%), and all weightings add up to exactly 100%. | Creating or editing the scorecard |
Criteria or questions | The individual items inside an area, such as Delivery Reliability. | Creating or editing the scorecard |
Score | A whole number from 0 to 5 for each criterion. | Applying the scorecard, or scoring a supplier's responses |
How the score is calculated
Step | Calculation |
1. Average each area | Add the scores of the criteria in the area and divide by the number of criteria. |
2. Weight each area | Divide the area's average by 5, then multiply by the area's weighting. The result is the points that area earns out of its weighting. |
3. Add the areas together | The total of all the areas' points is the supplier's Score (%), from 0 to 100. |
Where you see each figure
Choose View in a scorecard result's Actions menu to see the breakdown:
Column | What it shows |
RATING SCORE | The 0–5 score given to each criterion. |
AREA WEIGHT | The area's weighting (%). |
OVERALL SCORE | The area's average score, to one decimal place. |
WEIGHTED SCORE | The points the area earns, rounded to a whole number. |
Total Weighted Score (%) | The supplier's Score (%), shown at the top. |
Rounding
Figure | How it's rounded |
Area average | Shown to one decimal place. |
Area weighted score | Shown rounded to the nearest whole number. |
Score (%) | Calculated from the unrounded area scores and saved as a whole number. If the scorer later edits the scorecard, the total is recalculated from the rounded area scores, so it can change by about a point. |
Score colours
Risk is calculated in exactly the same way. Only the meaning is reversed: on Risk scorecards 0 = low risk and 5 = high risk, so a higher Risk score is worse.
Tab | Green | Amber / Red |
Scorecards, Performance, Sustainability | Above 80% | Amber 61–80%, red 60% or less |
Risk | 20% or less | Amber 21–40%, red above 40% |
Common questions
Why doesn't an area with more criteria count for more?
Criteria are averaged within each area, so only the area's weighting decides how much it counts. To make an area count more, raise its Weighting (%).
Why did the Score (%) change by one point after the scorecard was edited?
Editing recalculates the total from the rounded area scores, while the original total was calculated before rounding. The difference is usually a point or less.
Why is a high Risk score shown in red?
On Risk scorecards, 5 means high risk, so a higher percentage means the supplier is riskier.
Is a self-assessment scorecard calculated differently?
No. You score the supplier's answers from 0 to 5 and the same calculation applies.
