Chapter 3 Shared Services — Standardization, Formalization, and Control: A Structured Literature Review

Purpose The purpose of this study is to offer an integrated literature review of shared services’ organizational structures by specifically focusing on centralization, specialization, control, and formalization mechanisms. Methodology/approach A sample consisting of 103 empirical and conceptual articles, identified in a structured literature search in Science Direct and Scopus, was analyzed. The focus was on exploring the structural dimensions of shared services in various fields: Supply Chains, Finance, Human Resource Management, and Information Technologies. Findings from the selected articles were codified alongside the structural dimensions drawn from contingency theory. Findings Most of the papers identified were concerned with the Human Resource function or with Accounting and Finance in the private sector. Purchasing was only mentioned in a few general articles and Marketing not represented at all, even though the literature suggests that shared services do exist in this field. This uneven distribution across fields, as well as the reality that many articles fail to make clear divisions between disciplines, is hardly conducive to identifying trends for individual disciplines, and only general trends for each dimension could be identified. Although centralization was one of the most discussed dimensions, there was no consensus as to whether shared services should be centralized or decentralized. Standardization and formalization were both found to be highly important, although a need for customization was also emphasized. Implications Future research should be oriented toward the structural dimensions of shared services in a broader range of fields as current findings are dominated by the Human Resource function. Another implication of our findings is that scholars could usefully test empirically the dimensions, especially those where opinions differed the most: centralization and specialization. Originality/value Earlier conceptualizations noted that the mixed shared service outcomes stem from the diversity in governance and several contingency factors. This work continues the exploration of the contingency factors and mechanisms that, through integration, allow shared services to respond to the environmental uncertainty. The value of this chapter is in examining the structures of different functional types of shared services that are reported as successful in the literature, thus offering an overview of best practices in organizing shared services.
