Expectations of manufacturing companies regarding future priorities of improvement actions taken by their suppliers

PURPOSE: The paper concerns supply chains. It aims to identify the essential improvement actions that manufacturing companies expect their suppliers to take in the future rather than selection requirements already used in the assessment process. Within those improvement actions, the goal is to determine whether the size and management methods used in assessing companies affect these future expectations. DESIGN/METHODOLOGY/APPROACH: Hypotheses were developed regarding the expectations of manufacturing companies and the factors influencing these expectations. Data collected from 118 companies from the Polish automotive, metal and chemical sectors were used to verify them. For this purpose, the U-Mann Whitney test was applied. FINDINGS: Manufacturing companies expect their suppliers to improve: (1) products, (2) processes, (3) organization management, (4) communication and (5) relationship, with the most important thing for them is the improvement of products and processes. It was found that the expectations regarding the contributors are influenced by whether the manufacturing company is a large or small enterprise or it uses or not the Toyota Production System. Lean Management and the ISO 14,001 Environmental Management System do not translate into these expectations. ORIGINALITY/VALUE: : The article gives a new look at shaping relations between suppliers and customers in supply chains. Unlike most of the research to date, it does not concern the requirements that suppliers should meet at a given moment but focuses on the improvement actions they should undertake in the future. This paper adds important detail to understanding cooperation in B2B relations.
