This paper presents and tests a model designed to provide feedback and continuous improvement during the process of supplier selection in agile supply chains (ASCs). In ASCs suppliers typically need to be changed or added to frequently in response to dynamic market conditions. The model seeks to capitalise on the increased application of the supplier section process by applying principles of continuous improvement and organisational learning. Its aim is to support organisational decision-makers in their efforts to optimise the performance of the supply chain by ensuring that only the most appropriate suppliers are selected at all times. The model was tested by application within two simulation groups of MBA and masters level international management students who have significant business experience. The results of a questionnaire, used to assess the efficacy of the model, showed that the participants found the model was likely to have significant benefits when used in practice.
