| # Calculating ratings for subjective criteria When you do a full update of the vendor ratings in the Update Vendor Rating (tdpur8850m000) session, the calculation of the ratings for the subjective criteria is the third stage in the calculate/update vendor rating procedure. To calculate the subjective criteria ratings: The subjective values for each business partner are retrieved from the Questionnaire Results (tdpur8193m000) session. Percentage values, which are stated in the Vendor Rating Subjective Values (tdpur8192m000) session, are assigned to the corresponding subjective values. The average rating for each subjective criterion is calculated per business partner. The overall rating of a business partner/subjective criterion combination is calculated as follows:

    Overall rating per criterion = SUM / OCC SUMAll percentage values that are assigned to one
    business partner/subjective criterion combination.OCCThe number of times that percentage values are assigned
    for the business partner/subjective criterion combination.
    A not applicable value is not taken into account.
Example 1 A business partner is rated on two subjective criteria by several employees: CS = Customer service DS = Delivery service
Subjective Criterion | Subjective Value | % value | Employee
--- | --- | --- | ---
CS | Average | 50 | Arthur
DS | Excellent | 80 | Arthur
CS | Good | 60 | Bob
DS | Good | 60 | Bob
CS | Poor | 40 | Carol
DS | Not applicable | ** | Carol
The overall ratings for the business partner/subjective criterion combination are: CS = (50 + 60 + 40) / 3 = 50% DS = (80 + 60 ) / 2 = 70% After the calculation, the ratings are displayed in these sessions: Vendor Ratings by Period (tdpur8102m000) Vendor Ratings by Criterion (tdpur8102m100) Example 2 The same example is used as stated above, but this time the subjective criterion CS contains three subcriteria. The subcriteria have the following weightings:
Subcriteria | Weighting
--- | ---
Flexibility | 0.4
Call Handling | 0.2
Support | 0.4
These percentage values are assigned:
Subjective Criterion | Subjective Value | % Value | Employee
--- | --- | --- | ---
Flexibility | Average | 50 | Arthur
Call Handling | Excellent | 80 | Arthur
Support | Poor | 40 | Arthur
DS | Excellent | 80 | Arthur
Flexibility | Good | 60 | Bob
Call Handling | Average | 50 | Bob
Support | Good | 60 | Bob
DS | Good | 60 | Bob
Flexibility | Poor | 40 | Carol
Call Handling | Excellent | 80 | Carol
Support | (not appl.) | 0 | Carol
DS | (not appl.) | 0 | Carol
Calculating the overall ratings LN calculates the overall ratings for the business partner/subjective criterion combination. Flexibility = (50+60+40)/3 = 50% Call Handling = (80+50+80)/3 = 70% Support = (40+60)/2 = 50% DS = (80+60)/2 = 70% Calculating the rating of the parent subjective criteria Parent criteria rating = sum (child criteria % values * weightings) Flexibility = 50% * 0.4 = 20 Call handling = 70% * 0.2 = 14 Support = 50% * 0.4 = 20 CS rating = 20 + 14 + 20 = 54% Writing the ratings After the calculation, LN writes the ratings to these sessions: Vendor Ratings by Period (tdpur8102m000) Vendor Ratings by Criterion (tdpur8102m100) Related topics Calculating vendor ratings Overview of vendor rating |
