In SAP Ariba's Supplier Performance Management, a survey's structure is hierarchical. The most granular, or detailed, level at which a score can be assigned is the individual Question. Each answer to a question can be configured with a specific numerical score. These individual question scores are then aggregated to calculate scores for Sections and the overall survey. When mapping survey results to a Key Performance Indicator (KPI), using the question-level score provides the most precise and detailed measurement of performance against that specific metric.

A. Requirement: A requirement is typically used to track compliance or gather specific information (e.g., a certification), often with a pass/fail outcome, not a scaled score, making it less granular for KPI measurement.

B. Attachment: An attachment is a supporting document or file. It does not have an intrinsic, quantifiable score that can be directly mapped to a KPI; it serves as evidence or context for an answer.

C. Section: A section's score is an aggregation of the scores from all the questions contained within it. Therefore, it represents a summary and is inherently less granular than the score of a single question.

1. SAP Ariba Supplier Lifecycle and Performance Documentation, "Scoring in surveys": This section details the scoring mechanism within survey documents. It explicitly states, "You can assign scores to acceptable answers for multiple choice questions in surveys... The total score for a survey is the sum of the scores for all questions in it." This establishes the question as the fundamental unit of scoring. (Accessed via SAP Help Portal for SAP Ariba Cloud Solutions).

2. SAP Ariba Supplier Lifecycle and Performance Documentation, "Survey documents": This guide outlines the components of a survey, describing the hierarchy where Sections contain Questions. This structural information supports the understanding that a question is the most basic element within a section. (Accessed via SAP Help Portal for SAP Ariba Cloud Solutions).

3. SAP Ariba Supplier Lifecycle and Performance Documentation, "KPIs in supplier performance management projects": This document explains how KPIs are used to measure supplier performance. It describes how KPIs can be linked to surveys, where the survey's score, derived from its questions, provides the data for the KPI calculation. The most granular input for this calculation is logically the individual question score. (Accessed via SAP Help Portal for SAP Ariba Cloud Solutions).
