A progress report - Framework to Achieve Optimal Granularity for Service-Oriented Systems
The improved interoperability and business agility of software systems based on Service- Oriented Architecture (SOA) has created an increased demand for the reengineering and migration of legacy software systems. The wide range of current migration techniques for legacy systems implemented in different technologies does not address important aspects of service granularity, which affects service reusability, governance, maintainability and cohesion. This report provides an introduction to the field and discusses the key issues. Following this, a literature review of practical SOA approaches for building distributed systems is presented. A novel framework for the effective identification of the key services in legacy code is then presented, based on defining the right services using standardized modelling languages (UML and BPMN). This framework provides effective guidelines for determining the optimal service granularity over a wide range of possible service types. Finally, an outline plan for the future PhD research is presented together with the overall conclusions

Abstract
The improved interoperability and business agility of software systems based on Service- Oriented Architecture (SOA) has created an increased demand for the reengineering and migration of legacy software systems. The wide range of current migration techniques for legacy systems implemented in different technologies does not address important aspects of service granularity, which affects service reusability, governance, maintainability and cohesion. This report provides an introduction to the field and discusses the key issues. Following this, a literature review of practical SOA approaches for building distributed systems is presented. A novel framework for the effective identification of the key services in legacy code is then presented, based on defining the right services using standardized modelling languages (UML and BPMN). This framework provides effective guidelines for determining the optimal service granularity over a wide range of possible service types. Finally, an outline plan for the future PhD research is presented together with the overall conclusions
