The key constructs and causal relationships underpinning supply chain dynamics have long been established but this understanding is not readily related to more recently developed supply chain models and theory. The purpose of this paper is to use a case to investigate how selected constructs (variation, uncertainty, performance trade‐offs and buffering mechanisms) may be used to show the dominant causal relationships and through that enhance the theoretical explanation of such models.
The paper uses a single case study that was selected because the transition in supply chain management strategy clearly questioned the need for improved causal reasoning. The case research sources include interviews, temporal performance data and multiple site visits across three echelons of the supply chain.
The cause and effect logic underpinning the case transition have been explained and mapped using these constructs which have then been used to propose enhancements to the Fisher supply chain strategy model in generalising theoretical guidance.
These constructs, together with the generic strategies, provide additional clarity concerning generic options for strategic improvement as well as causal understanding of the buffering implications.
This paper uses a case study to enhance current theory by exploring means of better supporting theoretical prediction and explanation.
