Is there a key performance indicator (KPI) for "not ready time"? How can I
calculate this metric – for example, for an agent who is required to be available eight hours to
Most call center and call routing systems provide measurements for the time a representative
is signed into the system and "not ready" to take a call, as well as the overall time they are
logged onto the system to handle calls. Most systems allow the agent to indicate and the system to
track at least a basic degree of the reason for not being ready to take calls to distinguish call

unavailable for wrap-up or other reasons. The amount of time allowed is specific to your center's
needs. It is not uncommon to see the unavailable time targets for non wrap-up in the 4% -- 8%

Example of unavailable
<8 Hour Shift - 2 x15 Min Breaks - 1x 30 Min Meal = 420 Total Available Minutes (100%).
An unavailable time target of 5% would allow for 21 minutes of unscheduled time away from the
