Availability is no longer a good enough measure of performance, service or satisfaction. Have you looked at your key performance indicators? How do you collect them and how you can present them to your clients?
Do not focus solely on the performance counters that can be collected automatically from systems. Talking to people within your organisation to see how you are performing can be argued to be more important as this gives you information on the perception of the services provided and not simply the performance of the systems providing the service.
A carefully worded survey requesting objective responses that can be collated and trended over time can help steer your efforts in the right direction and provide support for service improvements and new projects.
The performance counters automatically provided by the systems can give users a sense of ownership in their service through visible heads up on problems, transparency of current status but only if the information is aligned to the services and not technology.
