The growing complexity of IT services poses new challenges to IT Service Management (ITSM). The issue of end-to-end service quality challenges service providers, as most services are no longer realized stand-alone by a single provider but composed of multiple building blocks supplied by several providers. In the past, relationships between service providers were organised according to a hierarc...

Information Technology Service Management (ITSM) provides a framework to provide IT related services and the interaction of IT staff with users, and is often related with the British Government’s Information Technology Infrastructure Library (ITIL). ITIL offers a set of “best practices” for managing IT services and is one of the most widely accepted approaches to IT service management in the wo...

Scientific computing relies heavily on e-Infrastructures as one of the cornerstones of today’s advancements in research. These e-Infrastructures include advanced IT architectures such as supercomputers, grids, clouds, and the networks interconnecting them. In order to deliver high-quality services provided by these systems to the users, adequate IT management is an essential requirement. The Le...

• Large-scale field experiments demonstrate the ultra-wide first bandgap. Achieve a bandgap with relative bandwidth of 1.17. Study characteristic by using complex band structures. Seismic metamaterials (SMs) are expected to assist or replace traditional isolation systems owing their strong attenuation seismic waves. In this work, one-dimensional inverted T-shaped SM (1D ITSM) composed arrays st...

Process improvements within ITSM are guided by prescriptions of frameworks like ITIL and ISO 20000. Since improvements cause costs, they need to be beneficial to the respective organization. This means to implement ITSM process improvement frameworks according to the specific needs of organizations. In this research in progress a concept is presented that supports this approach by sharing knowl...

Large IT service management (ITSM) project has high complexity and low success in implementation. Five common killer assumptions are selected from Warfield’s 17 Killer Assumptions through empirical analysis. Enterprise interview and questionnaire survey are used to establish and verify the relational model between the root risk factors of implementation of the ITSM project and the six complexit...

IT service management (ITSM) is of increasing significance to IT organizations, while at the same time information systems (IS) play a crucial role for many organizations around the world. Universities represent the first step for students to gain a qualification in the field of ITSM; as such, the university educates the future employees of IT organizations. This contribution describes the moti...

Many organizations are embracing ITIL as a model for best practices. This paper provides a brief background of ITIL and the ITSM processes, with particular attention paid to Capacity Management. The author also considers two different organizations and discusses Capacity Management as practiced in those environments, comparing and contrasting those practices with ITIL Capacity Management. Final...
