Capacity Utilization
The percentage of available production capacity that is actually being used to produce goods. Capacity utilization helps managers understand how efficiently resources are being employed and whether additional capacity is needed or if existing capacity could handle more volume.

Throughput
The rate at which a manufacturing system produces finished goods, typically measured as units per hour or per shift. Throughput is determined by the system's bottleneck operation and represents the actual productive output that generates revenue.
Overall Equipment Effectiveness
A metric that measures manufacturing productivity by multiplying three factors: Availability (uptime), Performance (speed), and Quality (good units produced). An OEE score of 85% is considered world-class, while most manufacturers operate between 60-70%. OEE identifies losses and improvement opportunities in equipment utilization.
Bottleneck
The operation or resource in a production process that limits overall system throughput because it has the lowest capacity or longest cycle time. Identifying and managing bottlenecks is critical because improving non-bottleneck operations does not increase total system output.
Downtime
Periods when equipment or production lines are not operating, whether due to breakdowns, changeovers, maintenance, or lack of materials. Downtime directly impacts productivity and OEE, making its reduction a primary focus of maintenance and operations improvement efforts.
