Once you have successfully completed the ITFM pathway, you need to periodically assess the effectiveness of your ITFM program & determine if you are realizing the benefits that you expected.
Interviews
You should perform follow up interviews with the same business leaders that you first spoke with at the beginning of this project to gauge their level of satisfaction
Use the same questions & have them rate their level of overall satisfaction with IT, then you can compare & measure the differences before & after the project & respond accordingly.
