In the V8 TRACC Platform, an assessment maturity rating is calculated based on the sum of the yes responses per stage, per theme, using the following algorithm:
-
Theme maturity = 1 + Stage2 + (Stage2 x Stage3) + (Stage2 x Stage3 x Stage4) + (Stage2 x Stage3 x Stage4 x Stage5)
-
Assessment maturity = average (theme maturity)
Note:
- The Latest Verified Maturity is calculated using this algorithm, but uses the latest verified Yes responses.
- The Current Ad Hoc Maturity is calculated using this algorithm, but uses all the latest Yes responses.
Consider the following assessment example:
Step 1
The percentage value for each stage in a theme is calculated by dividing the number of ‘Yes’ responses by the total number of criteria in the stage. In this example, three responses of ‘Yes’ out of a total of four criteria in Stage 2 of Theme 1 equates to 75% (or a rating of 0.75) for the stage.
Step 2
The maturity rating for the theme is calculated using this algorithm:
1 +
Stage2 +
Stage2 x Stage3 +
Stage2 x Stage3 x Stage 4 +
Stage2 x Stage3 x Stage4 x Stage 5
In this example, the rating calculated is:
1 +
0.75 +
0.75 x 0.5 (0.375) +
0.75 x 0.5 x 0.5 (0.1875) +
0.75 x 0.5 x 0.5 x 0.25 (0.046875)
= 2.359375 (rounded off to 2.36)
Step 3
The overall assessment maturity is then determined by averaging the theme maturities.
In this example, the overall assessment maturity is calculated by adding all the total theme maturities and dividing by six (the number of themes), as follows:
2.36 + 1.94 + 1.33 + 1.33 + 1.33 + 1.33
÷ 6
= 1.60
