Schedule Adherence

Schedule adherence is a workforce management metric that measures how closely an agent follows their assigned work schedule — clocking in on time, working during assigned hours, taking breaks only during designated windows, and minimizing unscheduled absences.

Schedule Adherence Formula

Adherence % = (Time worked according to schedule / Total scheduled time) × 100

A scheduled agent must be present and ready to take calls during their shift; unplanned absences, tardiness, and extended breaks reduce adherence.

Why It Matters

• Coverage: If 80% of scheduled agents are actually available, coverage drops; wait times and abandonment increase.
• Erlang C planning: Staffing models assume a certain adherence level; poor adherence causes understaffing.
• Cost: Paying agents for hours they didn't work increases labor cost per contact.

Schedule Adherence Targets

• Excellent: 95%+ adherence (agent rarely late or absent).
• Good: 90-95% adherence (occasional late arrivals or unplanned breaks).
• Poor: Below 90% adherence (frequent absences or extended breaks).

How AI Voice Agents Improve Adherence Challenges

AI agents reduce the need for human agents, so staffing can be right-sized. Even with lower adherence rates, total capacity remains stable because AI backs up human agents during call spikes or when agents are unavailable.
