What is a Process Capacity Sheet?
The Process Capacity Sheet is Form 1 of the three standardized work documents. It calculates the true production capacity of each machine in a process sequence. By documenting manual time, auto time, completion time, and tool change requirements, you can identify which machine is the bottleneck — the constraint that limits the entire line's output.
Also called the "Process Capacity Table." It answers: "Can we actually make enough parts to meet customer demand?" Complete Form 1 before creating the Standardized Work Combination Table (Form 2) or the Standardized Work Chart (Form 3).

Formula Reference
Basic Capacity (no tool changes)
Capacity = Available Time ÷ Completion Time
Available time is typically 27,600 sec (460 min) per 8-hour shift with breaks.
Adjusted Capacity (with tool changes)
Capacity = Available Time ÷ (Completion + Change Over Time ÷ Lot Size)
The changeover time is amortized across each piece in the lot, increasing the effective time per piece.
Key Concepts:Bottleneck — lowest capacity step limits entire lineMManual — operator hands-on time (sec)AAuto — machine runs unattended (sec)CCompletion — total elapsed time per piece
