Supplement to the Article: How Product Representation Influences the Understanding of Supply Chain Process Models

This document provides additional data analysis for a laboratory experiment that assessed the usefulness of two alternate product representations in so called SCOR thread diagrams (Leukel & Sugumaran 2018). Such diagrams are a form of supply chain process model, which represent the logic of product flow within a supply chain. The modeling grammar for thread diagrams is part of the Supply Chain Operations Reference (SCOR) model, which is the industry-standard for supply chain analysis. This supplement consists of the following parts: (1) Experimental design, (2) testing for order effects, and (3) correlation matrix.
