Occupancy Differs From Utilization

Occupancy differs from utilization, in that occupancy considers only live logged in time, but utilization considers total time at work (including logged out time such as training).

Occupancy Formula

Occupancy = What percentage of time that my agents are logged in live, are they actually productively busy with a customer activity, or are they available to do more?

The typical formula to calculate occupancy is:

(Talk + Hold + Wrap + Customer Related Activities) ÷ (Talk + Hold + Wrap + Customer Related Activities + Available Time)

Occupancy is especially important in schedule design, as it assists with measuring schedule optimization, so as not to have agents sitting and waiting for calls.

Utilisation Formula

Utilization = What percentage of the time that I pay my agent, are they logged in and assisting or available to assist with a customer activity?

The typical formula to calculate utilisation is:

(Talk + Hold + Wrap + Customer Related Activities + Available Time) ÷ (Paid Hours On-Site / Total Shift Time)

Utilization is important as input to shrinkage or overhead calculations, as it considers “non customer-related activities” that still get paid for, but that takes the agent away from servicing a customer, such as:

  • Training Time
  • Coaching
  • Personal Breaks
