Information Technology or IT is a combination of technology itself and a collection of IT services that ensure the effective implementation of overall Information Technology in an organization. Like other services, Information Technology Service Management (ITSM) has become a global subject because managing IT is only possible through efficient and effective ITSM protocols. A well-implemented ITSM delivery system improves the quality of IT services, which eventually enhances the organization's overall capacity and output. Public service delivery is closely dependent on the quality IT services that can be acquired through ITSM. This research study reviews some of the established ITSM standards and frameworks like FitSM, ITIL, CobiT, and ISO/IEC 20000 and proposes a most suitable and sustainable tool and its implementation roadmap for the digital transformation of public sector governance. For this pilot study, a public sector organization (PSO) working under the Government of Punjab (GoPb) was selected. This study focuses on an important area that has not yet been adequately addressed, where ITSM delivery can produce tremendous results. This study contributes to academics and researchers since it discusses the selection and implementation of a service management system (SMS) for a PSO while focusing on its needs, requirements, and available resources. In general, the qualitative analysis methodology is used in this research study, and specifically, it can be identified as applied research. The data is collected through a questionnaire, and the results are shown and discussed in the later sections.
