Service modularity: literature overview of concepts, effects, enablers, and methods

ABSTRACT The literature on service modularity is still scarce, and a comprehensive review, encompassing the main aspects related to its implementation, has not yet been addressed. This paper presents an overview of service modularity concepts, effects, enablers, and methods by conducting a systematic literature review. The review considers 67 peer-reviewed journal articles, published from 1994 to 2017. This work outlines the evolution of the service modularity field and discusses its specific features and main concepts. The results demonstrate that: (i) most service modularity literature is still based on a product modularity theoretical background; (ii) there is no consensus regarding the definition of a service module; (iii) the literature emphasizes the benefits expected from service modularization and, in general, neglects its risks; and (iv) there is a lack of methods and tools to support the testing and interface definition phases of service modularization. Finally, this work also provides direction for future research.
