Collaborations for Service Innovation in low-tech sectors: Evidence from SMEs Italian wineries

Paper 1 (Chapter 2): This article aims to map the development of studies related to servitization and Product-Service Systems (PSS) to examine and discuss the main findings of the scientific literature. The study is based on co-occurrence analysis, co-citation analysis and bibliographic coupling of 421 articles selected using Vosviewer software. By identifying thematic clusters, the study underlines the growing interest in the field of servitization and the development of a product-service system. In recent times, in addition to the development of the architecture of services, solutions, and Product-Service System, the development of strategic methods of servitization and PSS, the authors are opening a new field of research by combining digitization with these new business practices, demonstrating the characteristics of servitization research. Several research gaps emerged from this literature review. This bibliometric analysis is based solely on the Web of Science databases. The future use of other databases such as Inspec, EI Compendex and Scopus is not excluded. In addition, the work provides an overview of the servitization literature using a bibliometric analysis to identify key research topics. Next, the study examines the concept of PSS to detect the evolution of the literature and its definition and implementation.
