Service supply chain management process capabilities: Measurement development

The role of supply chain management processes in achieving competitive advantages in the service industry has been widely discussed. However, due to the lack of valid measurement scales, the effects of service supply chain management (SSCM) process capability cannot be ascertained. This study aims to develop and validate measurement scales for SSCM process capability constructs. The measurement scales were initially developed by literature review, and refined by Q-sort method. The SSCM process capability is a seven-dimensional construct; each dimension consists of a collection of unidimensional multi-item scales. Confirmatory factor analyses of a large-scale survey confirmed the unidimensionality, reliability, and validity of the multidimensional construct of seven SSCM process capabilities. The validated measurement scales lay a crucial foundation for advancing knowledge of the service supply chain by enabling future empirical studies in the field, which previously relied on largely conceptual frameworks and descriptive accounts of SSCM processes.
