Modelling Uncertainty Effects in Decision Taking in Buyer-Supplier Relations

Purpose: To develop a model that shows the different aspects that play a role in decision making in buyer-supplier relations when facing uncertainty.

Methodology: Process steps and relevant aspects were distilled from a broad literature review and evaluated in a Mini-Delphi style workshop.

Findings: An accumulative three-layered model shows (1) the assumed decision flow of the decision maker’s process under uncertainty; (2) the assumed behavioural aspects affecting this decision flow; (3) manifest variables and latent constructs related to the decision flow.

Relevance: The proposed model is designed to be used for surveys and gamification experiments, with relevant operationalised variables made explicit.
