Capacity Sheet

Standardized Work Form 1

1/8

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.

What is a Process Capacity Sheet?

The Process Capacity Sheet (PCS) — Form 1 of the three core standardized work documents — answers a fundamental question: can we actually make enough parts to meet customer demand? For each machine or process step, it calculates the maximum number of parts that can be produced in a shift, accounting for manual time, auto time, and tool change frequency.

The process with the lowest capacity is the bottleneck. Knowing the bottleneck before building the Standardized Work Combination Table prevents wasted effort — there is no point balancing work across operators if a single machine cannot keep up with takt.

When to use this tool

Complete the PCS before any other standardized work document. It is especially important when introducing new products, changing takt time, or investigating chronic shortages. The capacity data also feeds into OEE calculations by quantifying the gap between theoretical and actual output.
