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.

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.
