摘要
Computational methods and systems for detecting cost outliers in various information technology (“IT”) services provided an IT service provider are described. In one implementation, bills of IT generated for each billing period are converted into corresponding cost-flow models with expense nodes. Each expense node represents a cost for a particular IT services purchased during a billing period. The method searches the expense nodes over the billing periods for cost outliers, and rank orders the cost outliers. The method then analyzes the cost outliers in order to identify a possible root cause for each cost outlier. The rank order and possible cost outliers are stored in a data-storage device.
