An Empirical Method to Derive Principles, Categories, and Evaluation Criteria of Differentiated Services in an Enterprise

Abstract

Enterprises are leveraging the flexibilities as well as consistencies offered by the traditional service oriented architecture (SOA). The primarily reason to imply SOA is its ability to standardize way for formulating separation of concerns and combining them to meet the requirements of business processes (BPs). Many accredited research efforts have proven the advantages to separate the concerns in the aspects of one or more functional architectures such as application, data, platform, and infrastructure. However, there is not much attention to streamline the approach when differentiating composite services derived utilizing granular services identified for functional architectures. The purpose of this effort is to provide an empirical method to rationalize differentiated services (DSs) in an enterprise. The preliminary contribution is to provide abstract principles and categories of DS compositions. Furthermore, the paper represents an approach to evaluate velocity of an enterprise and corresponding index formulation to continuously monitor the maintainability of DSs.
