Purpose: The study extends customer-led co-creation research to the related staff-led value co-creation domain. In particular, the purpose of this paper is to investigate the role of staff engagement as a facilitator of staff-led value co-creation. Design/methodology/approach: A new conceptual framework develops a model of staff-led value-creation, using three types of staff-led co-creation. A quantitative approach is used. Survey collection yielded a sample of 1,165 employees in an Australian not-for-profit context across 19 organizations. AMOS structural equation modeling analyzes the data. Findings: A major finding is the nexus between staff engagement and staff-led value co-creation. The nexus applies for three types of staff-led co-creation and three staff categories. Different explanatory mechanisms apply to each type of staff-led value co-creation. Research limitations/implications: The not-for-profit context may not generalize to the for-profit sector, but future research could clarify this matter. Practical implications: The results can inform organizations wishing to create greater service contributions through greater staff participation, which can include a staff-initiating (staff-led) role. Different value co-creation targets require different corporate triggers, reflecting the different explanatory mechanisms of each co-creation type. Social implications: Not-for-profit context ensures major social implications. Originality/value: The emphasis on staff-led value co-creation augments the customer-led co-creation literature. Additionally, exploring the (staff) engagement to (staff) value co-creation nexus is a novel contribution.
