A workforce management (WFM) system is designed to optimize contact center staffing by accurately forecasting customer demand and scheduling agents to meet that demand. This is the core of capacity planning. Agent utilization is a key performance indicator (KPI) that measures the percentage of an agent's paid time spent on productive activities. A successful WFM implementation improves capacity planning by ensuring the right number of agents are scheduled at the right times, which directly optimizes the agent utilization rate, preventing both understaffing (burnout) and overstaffing (inefficiency).

A. Number of closed cases: This is a productivity metric that measures output but does not directly reflect the efficiency of capacity planning or agent scheduling provided by a WFM system.

C. Deflection rate: This metric measures the effectiveness of self-service channels (e.g., knowledge bases, chatbots) in preventing cases from reaching an agent, not the management of the agent workforce itself.

1. Salesforce Help - Workforce Engagement: The official documentation states, "Workforce Engagement helps you forecast service case volume and agent demand. Then you can create agent schedules based on that forecast... to make sure that the right agent with the right skills is available at the right time." This directly links the WFM tool to capacity planning (forecasting and scheduling), for which agent utilization is a primary success metric. (See "Get Started with Workforce Engagement" section).

2. Salesforce Help - Prebuilt CRM Analytics Dashboards for Service: The "Agent Supervisor" dashboard within the Service Analytics documentation includes metrics focused on agent performance and capacity, such as "Avg. Handle Time" and "Cases Handled." Agent utilization is a composite metric derived from these core measures of agent activity versus their scheduled time, reflecting the efficiency of the schedule created by a WFM system. (See "Service Analytics Prebuilt Dashboards" documentation).

3. Salesforce Trailhead - Contact Center Metrics: The "Learn Contact Center Basics" module explains fundamental KPIs. It describes how balancing agent workload is critical. Agent utilization is the direct measure of this balance, which a WFM system is implemented to control and optimize. (See "Measure Contact Center Success" unit).
