Reputation and Reliability
Reliability is similar to availability in a lot of ways. It is different in that it is mainly influenced by our ability to keep our word. My reliability as a teammate is measured by the distance between what I say will happen and what actually happens. Over-promising and under-delivering will build a bad reputation just as fast as constant tardiness. We are relied upon as a teammate and when we let our teammates down, they will remember it. Teammates who are burned by our word enough times will eventually hesitate when we give it in the future.
