This document discusses schedule adherence in contact centers. It defines schedule adherence and factors to consider when setting adherence goals, such as scheduled hours, average handle time, and non-productive time allowed. The document provides calculations from ICMI on how to determine adherence targets based on these factors. It discusses how changing average handle time can impact goals and service levels. Finally, it discusses strategies for improving adherence, such as setting realistic goals, accurate forecasting, efficient scheduling, training agents on the importance of adherence, and holding employees accountable. Not meeting adherence goals can require more full-time employees, inconsistent customer service, and higher occupancy rates.
