This document discusses the importance of customer participation in service delivery and outlines strategies for enhancing that participation. It notes that customers play key roles as productive resources, contributors to quality and satisfaction, and sometimes even competitors. When customers do not understand or are unable/unwilling to perform their roles, or when their needs are incompatible, it can widen the service performance gap. The document recommends defining customer roles, recruiting and educating the right customers, rewarding contributions, and managing compatibility to improve participation.
