The invention broadly and generally provides a method of quantifying the complexity of an information technology management process, the aforesaid method comprising: (a) obtaining process-related data for the aforesaid information technology management process; wherein the aforesaid process-related data defines: at least one task, at least one role, and any number of business items which can be transferred between a plurality of roles within the aforesaid at least one role while executing the aforesaid at least one task; (b) creating a set of process component complexity metrics by applying a process complexity model to the aforesaid process-related data, the aforesaid process complexity model comprising at least one relationship of properties selected from the roles, tasks, and business items; and (c) creating a value representing the complexity of the aforesaid information technology management process from the aforesaid set of process component complexity metrics. The method disclosed is particularly useful, where the aforesaid process-related data defines at least one task comprising a decision point.
