Scorecards in oboloo are calculated using a weighted scoring method against predefined categories and areas. This user guide will outline the process of calculating scorecards effectively.
Understanding the Scorecard Structure
- Each scorecard is composed of categories/areas for evaluation.
- Categories represent overarching themes or aspects of evaluation (e.g., Performance, Cost Effectiveness).
- Criteria's are specific criteria within each category (e.g., Delivery Reliability, Pricing Competitiveness).
Scores
- Evaluate each criteria according to the predefined scoring scale of 0-5. For the scorecards, performance and sustainability tabs, 0 = lowest score and 5 = highest score. However for the Risk tab the scoring calculation is reversed where 0 = Low Risk and 5 = High Risk
- Input the score for each area based on the performance or criteria observed.
Applying Weightings
- Assign weightings to each category/area based on their relative importance. Higher weightings indicate greater significance in the overall evaluation
- Weightings determine the impact of each category/area on the overall score.
- Ensure that weightings sum up to 100% to reflect the complete evaluation coverage.
- Weightings can only be applied when creating or editing a scorecard, not when applying the scorecard against a supplier.
Calculation Process
Step 1: Retrieve User Ratings
- The system retrieves the ratings provided by users for each criterion within the scorecard (the 0-5 ratings given by the user when applying the scorecard against a supplier)
Step 2: Apply Weightings
- The system applies the predefined weightings to the ratings for each criterion.
- Weighted scores are calculated by multiplying the user rating by the corresponding weighting percentage.
Step 3: Aggregate Scores for Criteria
- The weighted scores for all criteria within each category are aggregated.
- This process involves summing up the weighted scores to obtain a total score for each category.
Step 4: Calculate Overall Score
- The system calculates the overall score for the entire scorecard.
- This is done by summing up the total scores for all categories.
Example:
oboloo Calculation:
1. Retrieve User Rating: User input: 4 out of 5 for each of the criterion under the category 'Performance'
2. Average All Criterion Scores Under the Category: 4 - there are 3 scores under the category performance in the screenshot above, therefore the average score for the entire category would be 4.
3. Apply Weighting: Weighting for the category Performance: 40%
4. Calculate Weighted Score:
- Weighted score = Average user rating * Weighting
- Weighted score = 4 * 40% = 1.6
6. Result: The weighted score for the criterion "Delivery Reliability" is 1.6 out of 5
7. Overall Category Percentage Calculation: - oboloo turns the weighted score of 1.6 into a percentage out of 100% for the scorecard,
- Percentage Score=Weighted Score/Maximum Possible Score×100%
In this case, the maximum possible score for each criterion is 5 (since the rating scale is from 0 to 5). Therefore, oboloo does the calculation of:
Percentage Score=1.6/5×100%=0.32×100%=32%
So, the percentage score for the whole 'Performance' category in the above screenshot on the scorecard is 32%.
