New Scoring model for calculating Max Achievable Score (MAS): Best Branch Approach
Max Achievable Score (MAS) as the name suggests is the maximum score that a supplier can receive for answering a particular questionnaire.
MAS is calculated during designing the questionnaire and is fixed once the questionnaire is published.
Conditions/logic inside a questionnaire is used to make a certain question visible or required based on the answer to other question. This allows questionnaire designer to ask more specific questions based on the previous response and display only relevant questions to the respondent.
If a questionnaire does not contain conditional questions, the MAS is simply the sum of MAS of individual questions. However, with conditional questions the logic to calculate MAS becomes complex.
Best Branch Approach: If a questionnaire contains conditional questions, it means there are several scenarios in which the supplier can respond to the questionnaire. Our model considers all the different scenarios and then calculates the MAS.
Detailed Example:
This questionnaire contains 2 questions and Question 2 becomes visible only if Question 1 is answered as ‘No’.
The scoring is assigned in the following way:
Q1: Yes: 100 Points, No: 0 Points
Q2: Yes: 50 Points, No: 0 Points
There are three possible scenarios in which the supplier can answer this questionnaire.
Scenario 1 | Scenario 2 | Scenario 3 | |
|---|---|---|---|
Question 1 | Yes | No | No |
Question 2 | Cannot answer | Yes | No |
Score Achieved | 100 | 50 | 0 |
In this case the MAS calculated is 100. The supplier cannot receive 150 points because if Q1 is answered ‘Yes’, Q2 will never be visible.
