Schedule Adherence is a fundamental metric in the contact center industry, serving as the backbone for operational efficiency and workforce management. This measurement quantifies how closely an agent follows their assigned work calendar, ensuring the right number of personnel are available to handle customer demand at all times. A high adherence rate is a direct indicator of a reliable staffing model, which has a profound impact on customer experience and a center’s financial performance. Understanding this metric is important for agents seeking to manage their performance and for managers aiming to optimize service delivery.
Defining Adherence in the Call Center Context
Schedule Adherence measures the percentage of time an agent is performing the task they are scheduled to perform, precisely when they are scheduled to perform it. Workforce Management (WFM) teams use this metric to gauge an agent’s compliance with their pre-planned schedule, which includes time for handling customer interactions, attending meetings, and taking breaks. The core purpose of tracking adherence is to ensure that staffing levels match the forecasted customer volume for every interval of the day. Adherence is purely a measure of punctuality and schedule compliance, not the quality or productivity of the work itself.
How Schedule Adherence is Calculated
The calculation for Schedule Adherence compares the time an agent spends working according to the plan against the total time they were scheduled to work. Workforce management systems automatically track this activity, which is typically expressed as a percentage. The standard formula subtracts any time spent out of adherence from the total scheduled time, divides the remainder by the total scheduled time, and then multiplies the result by 100. For instance, if an agent is scheduled for 480 minutes of work but is out of adherence for 30 minutes, their score would be 93.75 percent.
Activities That Impact Schedule Adherence
Schedule adherence is affected by every activity an agent performs during their shift, and WFM software categorizes these actions to track compliance in real-time. Adherent time includes all activities that are performed exactly as they appear on the agent’s schedule. Non-adherent time consists of any activity that deviates from the planned schedule, which negatively affects the final score.
Adherent Time Examples
Time spent handling customer interactions, such as taking inbound calls or engaging in live chat sessions, is considered adherent when it occurs during a scheduled contact time. Scheduled breaks, lunches, and designated periods for after-call work are also counted positively toward adherence. Furthermore, any scheduled offline activity, such as team meetings, one-on-one coaching sessions with a supervisor, or mandatory training, contributes to an agent’s adherent time.
Non-Adherent Time Examples
Non-adherent time includes actions like logging into the work system late or logging out before the scheduled end of a shift. Taking a break or lunch that extends beyond the allocated time slot, even by a few minutes, counts against the adherence score. Any unscheduled time spent away from the work station, such as an impromptu meeting, an unapproved personal break, or excessive idle time, is logged as non-adherent. These deviations cause a gap in staffing.
Why Adherence is Foundational to Operations
High Schedule Adherence is foundational to maintaining efficient call center operations and meeting service level agreements. When agents consistently follow their schedules, the workforce management team can rely on their staffing forecasts to be accurate. Low adherence immediately results in staffing gaps, creating understaffing during peak demand periods. This shortage of available agents directly causes the Average Speed of Answer (ASA) to increase, forcing customers to wait longer in the queue. Poor adherence complicates forecasting, often forcing centers to overstaff to compensate for the unreliability of their agents, which increases operational costs.
Strategies for Improving Your Adherence Score
Agents can take several proactive steps to maintain a high adherence score. One effective strategy involves integrating the work schedule into a personal digital calendar and setting automatic reminders for the start and end of every activity. This helps agents transition punctually between customer-facing time and scheduled offline tasks. It is also beneficial to use any predetermined grace periods wisely, ensuring that breaks begin and end within the few minutes allowed by the center’s policy. If an unavoidable delay occurs, such as a lengthy call that runs over into a scheduled break, the agent must immediately communicate this to their supervisor or the real-time WFM team. This action allows the WFM team to log the necessary exception code and prevents the delay from negatively impacting the agent’s adherence score.
Adherence Versus Other Key Call Center Metrics
Schedule Adherence is a distinct metric often confused with Conformance and Occupancy, which measure different aspects of an agent’s time management. Conformance measures the total amount of time an agent is logged into the work system compared to their total scheduled shift time, regardless of the precise timing of their activities. Occupancy is a measure of agent productivity, calculating the percentage of time an agent spends actively handling customer interactions and associated work versus the total time they are available to take calls. Adherence is about the agent’s commitment to the schedule’s timing, while Conformance and Occupancy address the amount of time spent working and the utilization of that time.
