Managing IT service management implementation complexity: from the perspective of the Warfield Version of systems science

The Warfield version of systems science supports a wide variety of application areas, and is useful to practitioners who use the work program of complexity (WPOC) tool. In this article, WPOC is applied to information technology service management (ITSM) for managing the complexity of projects. In discussing the application of WPOC to ITSM, we discuss several steps of WPOC. The discovery step of WPOC consists of a description process and a diagnosis process. During the description process, 52 risk factors are identified, which are then narrowed to 20 key risk factors. All of this is done by interviews and surveys. Root risk factors (the most basic risk factors) consist of 11 kinds of common mindbugs' which are selected from an interpretive structural model. This is achieved by empirical analysis of 25 kinds of mindbugs. (A lesser aim of this research is to affirm that these mindbugs developed from a Western mindset have corresponding relevance in a completely different culture: the Peoples Republic of China.) During the diagnosis process, the relationships among the root risk factors in the implementation of the ITSM project are identified. The resolution step of WPOC consists of a design process and an implementation process. During the design process, issues related to the ITSM application are compared to both e-Government operation and maintenance, and software process improvement. The ITSM knowledge support structure is also designed at this time. During the implementation process, 10 keys to the successful implementation of ITSM projects are identified.
