You can choose one of four formulas available to calculate the Total Score and determine your Top Priorities:

- Score Sum
- Value and Effort Sum
- Value Product divided by Effort
- Value Sum divided by Effort

The setting is separate for each board. The default is Value and Effort Sum.

**To change the formula:**

- Choose the board which you want to set up.
- Click the
**Criteria**menu. - Find the
**Board Formula**field. - Set the one you want to use on this board.

`Note! To set the board formula, you must be Admin in Ducalis.`

**1. Score Sum**

With this formula, the Total Score depends on the number of people who evaluate the issue. The more scores an issue has, the higher the total score is.

The criterion Score Sum is calculated as a sum of all scores multiplied by the criterion weight. We add up Score Sums of all criteria and get the Total Score.

*Note: Use negative weights for Effort criteria.*

**We can express the formula this way:**

Criterion Score (Cx) is the Sum of Scores (∑Sn) multiplied by the Criterion Weight (Wx).

**So we calculate:**

- Criterion X Score = (Score 1 + Score 2 + Score 3 + Score n) * Weight X
- Total Score = Criterion A Score + Criterion B Score + Criterion X Score

**For example:**

*3 users evaluated 2 criteria—Sales and Effort.*

The criterion ** Sales** has

**and scores:**

`weight +3`

`2; 3; 2.`

The criterion ** Effort** has

**and scores:**

`weight -2`

`0; 2; 1.`

Sales Score Sum = (2 + 3 + 2) * 3 = 21

Effort Score Sum = (0 + 2 + 1) * -2 = -6

**Total Score = Sales 21 + Effort -6 = 15**

**2. Value and Effort Sum**

With this formula, the Total Score doesn't depend on the number of people who evaluate the issue. It appears as if the team is one person because we calculate the average rating. We add up all the scores and divide the sum by their number. Then we multiply the resulting figure by the criterion weight. Thus we get the Average Score. Finally, we sum up the Average Scores of all criteria and get the Total Score.

*Note: Use negative weights for Effort criteria.*

**We can express the formula this way:**

Average Criterion Score (`ACx`

) is the Sum of Scores (`∑Sn`

) divided by the Number of Scores (`NS`

) and multiplied by the Criterion Weight (`Wx`

).

**So we calculate:**

- Criterion X Average Score = ((Score 1 + Score 2 + Score 3 + Score n) / N Scores ) * Weight X
- Total Score = Criterion A Average Score + Criterion B Average Score + Criterion X Average Score

**For example:**

*3 users evaluated 2 criteria—Sales and Effort.*

The criterion ** Sales** has

**and scores:**

`weight +3`

`2; 3; 2.`

The criterion ** Effort** has

**and scores:**

`weight -2`

`0; 2; 1.`

Sales Score Sum = ((2 + 3 + 2) / 3) * 3 = 7

Effort Score Sum = ((0 + 2 + 1) / 3) * -2 = -2

**Total Score = Sales 7 + Effort -2 = 5**

**3. Value Product divided by Effort**

With this evaluation formula, Value criteria are multiplied, and Effort—divided.

First, each criterion average score is calculated, i.e., all scores assigned are added up, and the sum is divided by their number.

Then, the average scores of all Values are multiplied, and, finally, the product is divided by the average score of the Effort criteria.

*Note: Don't use negative weights for Effort criteria.*

The formula allows you to set up the original RICE scoring.

**We can express the formula this way:**

- The Total Score (
`TS`

) is the multiplied Average Value Criteria (`ACval`

) divided by the Average Effort Criterion (`ACeff`

);`where`

- Average Criterion Score (
`ACn`

) is the Sum of Scores (`∑Sn`

) divided by the Number of Scores (`NS`

).

**So we calculate:**

- Criterion X Average Score = (Score 1 + Score 2 + Score 3 + Score n) / N Scores.
- Total Score = (Criterion A Average Score (val) * Criterion B Average Score (val) * Criterion C Average Score (val)) / Criterion D Average Score (eff).

**For example:**

`3 users evaluated 4 criteria—Reach, Impact, Confidence, and Effort.`

The criterion ** Reach** is

**and has scores:**

`Value`

**;**

`500`

**;**

`700`

**.**

`300`

The criterion ** Impact** is

**and has scores:**

`Value`

**;**

`3`

**;**

`1`

**.**

`5`

The criterion ** Confidence** is

**and has scores:**

`Value`

**;**

`80%`

**;**

`95%`

**.**

`65%`

The criterion ** Effort** is

**and has scores:**

`Effort`

**;**

`5`

**;**

`2`

**.**

`8`

**Reach** (* val*) Score = (500 + 700 + 300) / 3 = 500

**Impact** (* val*) Score = (3 + 1 + 5) / 3 = 3

**Confidence** (* val*) Score = ((80 + 95 + 65) / 3) / 100 = 0.8

`Note! When you use percents as scores, the average score is divided by 100.`

**Effort** (*eff*) Score = (5 + 2 + 8) / 3 = 5

**Total Score = (Reach (**

`val`

) 500 * Impact (`val`

) 3 * Confidence (`val`

) 0.8) / Effort (`eff`

) 5 = 1200 / 5 = 240**4. Value Sum divided by Effort**

With this evaluation formula, Value criteria are added up, and Effort—divided.

First, each criterion average score is calculated, i.e., all scores assigned are added up, and the sum is divided by their number.

Then, the average scores of all Values are added up, and, finally, the sum is divided by the average score of the Effort criteria.

*Note: Don't use negative weights for Effort criteria.*

The formula allows you to set up the original WSJF framework.

**We can express the formula this way:**

- The Total Score (
`TS`

) is the added up Average Value Criteria (`ACval`

) divided by the Average Effort Criterion (`ACeff`

);`where`

- Average Criterion Score (
`ACn`

) is the Sum of Scores (`∑Sn`

) divided by the Number of Scores (`NS`

).

**So we calculate:**

- Criterion X Average Score = (Score 1 + Score 2 + Score 3 + Score n) / N Scores.
- Total Score = (Criterion A Average Score (val) + Criterion B Average Score (val) + Criterion C Average Score (val)) / Criterion D Average Score (eff).

**For example:**

`3 users evaluated 4 criteria—User Value, Time Criticality, Risk Reduction, and Job Size.`

The criterion ** User Value** is

**and has scores:**

`Value`

**;**

`8`

**;**

`13`

**.**

`20`

The criterion ** Time Criticality** is

**and has scores:**

`Value`

**;**

`3`

**;**

`1`

**.**

`5`

The criterion ** Risk Reduction** is

**and has scores:**

`Value`

**;**

`13`

**;**

`5`

**.**

`5`

The criterion ** Job Size** is

**and has scores:**

`Effort`

**;**

`5`

**;**

`2`

**.**

`8`

**User Value** (* val*) Score = (8 + 13 + 20) / 3 = 13.66

**Time Criticality** (* val*) Score = (3 + 1 + 5) / 3 = 3

**Risk Reduction** (* val*) Score = (13 + 5 + 5) / 3 = 7.66

**Job Size**(

*) Score = (5 + 2 + 8) / 3 = 5*

`eff`

**Total Score = (User Value (**

`val`

) 13.66 + Time Criticality (`val`

) 3 + Risk Reduction (`val`

) 7.66) / Effort (`eff`

) 5 = 24.32 / 5 = 4.864
