Which of the following would BEST indicate to senior management that IT processes are improving?

The best indicator to senior management that IT processes are improving is the changes in the position in the maturity model. A maturity model is a framework that defines the levels of capability and performance of a process, such as IT processes, based on the criteria such as governance, management, control, measurement, and improvement. A maturity model can help to assess the current state and the desired state of the IT processes, and to identify the gaps, strengths, and opportunities for improvement. A maturity model can also help to communicate the progress and the value of the IT processes to the senior management, and to support the strategic alignment and integration of the IT processes with the business objectives. Changes in the position in the maturity model indicate that the IT processes are improving, as they show that the IT processes are moving from a lower level to a higher level of maturity, and that they are achieving higher standards of quality, efficiency, and effectiveness. Changes in the number of intrusions detected, changes in the number of security exceptions, and changes to the structure of the risk register are not as good as changes in the position in the maturity model, as they do not provide a comprehensive and consistent measure of the IT processes improvement, and they may not reflect the actual impact and performance of the IT processes. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 36.
