Slides (PDF, 1.6 MB)(PDF 1,7 MB)

Abstract - IT strategic outsourcing becomes an increasingly challenging business as customers demand improved quality of service while providers are driven to reduce the cost. While effective IT service management requires advances in many areas, the focus of this presentation is the application of machine learning techniques and predictive analytics to improving quality and efficiency of IT service delivery.  I will take a holistic perspective to classify service analytics research with respect to the target business problems and applied technical methods. Three key service analytics categories emerge in this perspective: (1) workload characterization to understand workload arrival patterns and service effort patterns, (2) performance prediction to gain insights into IT service assets and processes, and (3) process optimization to improve service management effectiveness. For each of the three categories I will summarize the goals as well as the analytics toolkit and present details on an implemented use case.
