The true benefit of ITIL processes in fulfilling the business requirements, with simultaneous adherence to the agreed service level agreements, only comes to the fore providing there is a coordinated interplay between people, processes and technology. Support tools are used for this purpose. However, the efficient control of the information flows between IT processes is only guaranteed providing a tool is used correctly and the basis created for the continual identification of potential improvements. The ITIL compatibility check, which has no ties to any manufacturers, verifies whether the ITSM tools used meet current and future requirements and whether these lend optimum support for the ITIL processes. This assessment is also suitable for providing a decision-making basis in the process of evaluating a new ITSM tool.
