One of the most important concepts in schedule adherence is shrinkage. Shrinkage can be defined as the time for which people are paid during which they are not available to handle calls.
There are many reasons that can cause shrinkage - and it has to be taken into account when scheduling the required number of agents to meet call volumes. But the truth is that most companies badly under-estimate the sheer volume of shrinkage that besets their call centers. This comes about due to a host of potentially hidden areas of shrinkage. Many managers keep their eye on several of these, but few are able to stay on top of all of them: lateness, talking to associates, personal calls and emergencies, leaving early and taking longer breaks. The bottom line on shrinkage is the amount of minutes per day that agents are being paid to be on the phone when they are not actually working or available to receive calls or work on customer related issues.
How to track and manage shrinkage?
Shrinkage can be a major factor in failing to meet service level targets. Call centers that take shrinkage parameters into account in their forecasting and scheduling typically achieve higher service levels at lower operating costs. They often do that by including all call related activities into the forecast and schedule planning process. Here is an example of how to track and manage shrinkage as part of the workforce scheduling process:
