How to Assess a Supplier's Production Capacity Before You Commit

Short answer: assess supplier capacity by asking how many machines they run, what percentage is currently committed, what their peak-season load looks like, and how much headroom they keep for reorders — then verifying the answers against the factory floor, past delivery performance and references. A supplier who says yes to everything is not necessarily able to deliver anything.

Capacity is the least visible risk in sourcing. A factory that looks capable on the showroom floor can be fully booked for your delivery window, and that only becomes obvious when your production runs late.

Why Capacity Assessment Matters

A factory's capacity is not a fixed number; it is capacity *available to you* in your window.

The Questions That Reveal Capacity

Ask directly, and listen for specificity:

Vague answers here are the signal. A factory that cannot state its machine count or utilisation is either a trader or badly managed.

Verify Against the Floor

What you were told should match what you see:

Test With Delivery History

Past behaviour in a peak month is the most honest capacity evidence available.

The Capacity Signals That Should Worry You

Plan Your Own Capacity Buffer

Capacity and the Business Model

Different models need different capacity profiles:

Match the factory's strength to your model, not the other way around.

Conclusion

Assessing capacity means asking specific questions — machines, utilisation, peak load, subcontracting — and then verifying them on the floor and in delivery history. A factory that answers precisely and shows you the lines is a factory with capacity you can plan against. A factory that agrees to everything without detail is a scheduling risk you are about to inherit.
