| # Calculating ratings for subjective criteria If 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 vendor rating calculation procedure. LN completes the following steps: Retrieves the subjective values per business partner from the Questionnaire Results (tdpur8193m000) session. Assigns the percentage values, which are stated in the Vendor Rating Subjective Values (tdpur8192m000) session, to the corresponding subjective values. Calculates the average rating for each subjective criterion 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, LN writes the ratings to the following 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
The following 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
To calculate 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% To calculate 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% To write the ratings After the calculation, LN writes the ratings to the following sessions: Vendor Ratings by Period (tdpur8102m000) Vendor Ratings by Criterion (tdpur8102m100) Related topics Calculating vendor ratings Overview of vendor rating |
