An Exploratory Study on the Relationship between Software Management and IT Service Management

Aims and Objectives: Information Technology (IT) service management has gained importance in the recent years. A service is a means of delivering value to the customers by facilitating outcomes, which customers want to achieve without ownership of the specific costs and risks. As IT services’ efficient execution revolves around its implementation through software management, the need for understanding the relationship between IT service management and software management has become crucial. The aim of this thesis is to explore this relationship. Methodology: We designed this thesis study as an exploratory study. First, a systematic literature review was conducted to explore the role of software engineering in IT service management and the interconnection between them. Then, we performed a case study at Telenor Sweden AB by conducting interviews in order to further investigate the intersecting elements between ITIL v3 Framework, which is an international standard for IT service management and software engineering considering ISO/IEC 12207 standard on software processes. Results: The outcome of this thesis is a mapping between IT service management and software engineering considering ISO/IEC 12207 for software engineering processes and ITIL V3 Framework for IT service management. These mappings have been recommended to use by the case company to incorporate ‘in-house’ software models in line with ITIL V3 Framework implementation. Conclusion: Though ITIL V3 framework gives in depth guidelines for IT Service Management, it does not give sufficient details for managing applications that constitute IT Services. As ITIL V3 is a framework, it is flexible to accommodate the software engineering processes defined in ISO/IEC 12207 standard. Though we brought three-way relationship between ITIL V3, ISO/IEC 12207 and case company’s software process models, it is found out that replacing existing models with ISO/IEC 12207 shall be difficult as it would be two new standards for the employees. The in house software process models are already inspired from standards. In this thesis, we provide a mapping between ITIL V3 and inhouse models of the case company to support the implementation of ITIL V3 for managing software applications to realize IT Services.The thesis gives mapping between ITIL V3 Framework and ISO/IEC 12207 Software Engineering processes to incorporate them in integrated Service Management and Software Management+4676250924
