Ariba Knowledge Nuggets

 

After completing the supplier outreach and creation of an RFI, your next step will be Scoring and Grading:

  • Consider using weighting and scoring functionality, to facilitate further analysis in less days than offline and with transparency/objectivity (between 2-4 days)
  • Involve site representatives and/or category stakeholders in defining parameters
  • Determine and assign values (pre-scores and weights) to the supplier questions
  • Determine deal breaker questions
  • Determine whether you want to display scoring to suppliers

 

WEIGHT

The Weight is the relative level of importance of this content element. It is used with the score you assign
each participant’s response and contributes to the overall score for each participant. Assign Weight points to
“container” content types such as sections and line items (for scoring purposes, a line item “contains” its
terms). Altering a section or lot’s weight allows you to alter the Overall % for all the section content.
For example, in the following graphic, there are 30 scoring points assigned to the Car Performance section,
and 70 to the Car Financing section. (Assign a total of 100 scoring points to cause the Overall % to be equal
to the number of assigned scoring points.)

IMPORTANCE
Assign importance scoring points to content types that require supplier answers, such as questions and line item terms. Assign each question between 0–10 importance scoring points, with 10 being the most important. Content to which you assign zero scoring points does not count towards the score. In the following graphic, question 1.2 has the highest importance with 10 importance points, and question 1.1 is half as important as question 1.2 with 5 importance points.

CALCULATION

Target Grade
When you run an event with scoring, you can put in a target grade for any item that is being scored. If the supplier’s grade falls below that target,
the grade is highlighted on the screen so you will be sure to notice it.

 

Pre-Grading

Pre-grading allows you to define rules in advance of an event to automatically assign grades. When you enter the grading page after the event you can modify the pre–grades. Use pre-grading to save time and to remove bias from your grading. For example, you might be tempted to grade your incumbent suppliers more favorably than their responses merit. Pre-grading is not available if the question does not have a pre-gradable answer type. For example, Ariba Sourcing cannot pre-grade questions with answer type Text (single line) because it cannot read and interpret sentences. However, questions with answer type Text (single line) can be pre-graded if you set the Acceptable Values option to List of Choices.

 

Number and Date Questions
Since questions that require numerical answers receive responses over a range of values, Ariba Sourcing performs a calculation to assign grades. The calculation is based on from, to, and ideal values that you specify.
Keep these points in mind:
  • The ideal value must be a number between the to and from values.
  • Negative numbers produce no special behavior. For example, assigning from = -5, ideal = 1, and to = 10 results in a pre-grade of 0% for -5, which ramps up to 100% for 1, and drops back down to 0% at 10.
  • Determine the range of likely answers to your question as accurately as possible and set the to and from values accordingly. If the to and from values are set too closely together, then some answers fall outside of the range and are assigned a grade of 0%. If they are set too far apart, Sourcing cannot assign a full spectrum of grades.

 

Grading the Supplier

 

Calculation of Overall Grade
The Total or Overall grade is a weighted average that Ariba Sourcing calculates by multiplying the overall weight percentage of each question by the grade that it received, and then summing all those values together. The formula is:

Using Team Grading
Team members can have differing opinions about what information is important as well as the quality of a
supplier’s responses. Team grading allows multiple team members to grade supplier responses to an RFI or
RFP event. A project owner can get information about team member’s opinions by having them grade
supplier responses to event content. Ariba Sourcing generates an average from these grades, and, if required,
the team members can come together to come up with a consensus grade for each supplier answer
particularly when there is disagreement on how to score specific participants and their responses.
Note: In team grading, the project owner is treated as any other team member and participates in the
consensus grading.
Team grading can include external graders. External graders are graders that are only allowed to provide
grades to participants responses, but they cannot view or access the event in any way. External graders can
provide a greater level of objectivity, since team members might be biased towards certain participants based
on historical experiences.
You can further add a level of objectivity by hiding the participant information from external graders (blind
grading). If blind grading is enabled, the supplier information is hidden and replaced with a uniquely aliased
name when grading responses.
(Examples)    

 

If a member of a grader group is also an individual grader, then that grader is removed from the group and the score is calculated using the weight assigned to the grader as an individual grader.

  • Example: Joe has been added as an individual grader with a weight of 100%, and he is also member of a grader group with 5 members, which has been assigned a weight of 80%. Joe is removed from the grader group (and therefore the remaining team members now each contribute 25% towards the group score), and the score is calculated using his individual weight of 100%, and the team weight of 80%.
Ensure that an individual member is not a member of two or more grader groups, since it can lead to random results. The weight of the first grader group that is read during score calculation is used to determine that user’s weight.
  • Example: Jane is a member of grader group A (40%) and grader group B (100%). If group A is read first during score calculation, Jane’s grade is weighted as part of group A at 40% total, if group B is read first during score calculation, Jane’s grade is weighted as part of group B at 100%.
