Requirement management for product-service systems: Status review and future trends

摘要

Many manufacturers today are striving to offer high value-added product-service systems (PSS) to their customers. Since the success of the PSS largely depends on the understanding and satisfying of different requirements, requirements management (RM) has become a critical factor in PSS development. However, PSS are mixed product-service offerings with features of heterogeneity, interaction, stakeholder participation and customization, which makes the PSS requirement difficult to be captured, analyzed, concretized and forecasted. Thus, this research analyzes the state of the art of requirements management for PSS by reviewing extensive literature of requirement identification, analysis, specification, and forecast. Based on the review, key challenges and future research directions are identified, and they are requirement elicitation considering interactions, hybrid PSS conflict detection and resolution, dynamic requirement forecasting with big data, smart requirement management and proactive response. This literature review lays the foundation for future research of PSS development. (C) 2016 Elsevier B.V. All rights reserved.
