What KPIs or metrics do you use to measure your own success?

For our department, we leverage network usage and performance metrics,  issue ticket resolution information, security risk data, from outside sources, to name a few.  These areas help to visualize the quality of the product we provide to our users.

Not sure if the term "own metrics" refers to personal aspects (resting rate, hours slept, kms ran, etc.). In any case, on a work environment I mainly use 3 types of metrics and almost all of them are related to my departments success: operations KPIs (ratio of incidents, survey results, % of automations, number of projects, etc.), projects KPIs (completed projects, accomplishes or deviations, ratios of incidents, ...) and some personal KPIs (courses or seminars made, feedback, etc.).

I have used some of these KPIs to measure success in IT Operations, Projects: Percentage of projects on time, on budget, on spec, average issue handle time, IT support employees per end users, MBTF, MTTR, RPO, RTO, Server downtime and uptime. 

We do an annual IT user survey whereby we request feedback on the performance of the IT team, this is measured annually to see how the team are fairing.

I use combination of KPIs defined in my performance objectives from my management, which include number of successful initiatives and projects completed, number of incidents addressed, etc.; in addition I define more soft-target KPIs, which include number of info sharing and product awareness sessions hosted and level of acceptance of Product Line roadmap by executives and peer product groups.
