What Is a Capability & Quality Audit?
A capability & quality audit is an on-site technical assessment of whether a factory has the equipment, systems, and competence to produce your product to a consistent standard. It is the core of a factory audit — focused on manufacturing capability and the quality management system (QMS), rather than on labour conditions or environmental practices.
Buyers use it to qualify a new supplier before committing, to monitor an existing supplier over time, or to investigate the root cause of recurring quality problems. Unlike a product inspection, which checks a finished batch, a capability audit tells you whether the supplier can reliably make good product in the first place.
What Does It Assess?
- Organisation & management — Ownership, management structure, years in operation, certifications held, and key customers.
- Facilities & equipment — Factory area, production lines, machine condition and calibration, and maintenance records.
- Production capacity — Output capability, capacity utilisation, and ability to meet your volume and lead times.
- Quality management system — Quality manual, documented SOPs, and quality records against a recognised QMS (e.g. ISO 9001).
- Process & quality control — Incoming material inspection, in-process controls, final inspection procedures, and handling of non-conforming goods.
- Testing & calibration — In-house testing equipment, calibration status, and access to third-party laboratories.
- Material management — Sourcing, storage, traceability, and inventory control.
- Workforce & training — Operator skill levels, training programmes, and supervision.
Scoring & Rating
Capability audits are scored against a structured checklist, producing a percentage score by category and an overall rating — typically Approved, Conditionally Approved, or Not Approved. The report includes detailed findings, photographic evidence, and recommendations, giving you an objective basis to approve, reject, or develop a supplier.
When to Use It
- New supplier qualification — Before your first order, to confirm a factory is legitimate and capable.
- Periodic monitoring — On a recurring basis to ensure standards are maintained.
- After quality problems — To find and fix the root cause at source.
- Dual sourcing — To compare candidate factories on an equal, objective basis.

Frequently Asked Questions
An assessment of a factory's production equipment, quality management system, inspection and testing capability, and process control — usually scored against a structured checklist.
Typically organisation and staffing, facilities and equipment, incoming-material control, process and production control, in-line and final QC, calibration, and corrective-action systems.
Buyers qualifying a new supplier, or reassessing an existing one — especially for technical, regulated, or higher-risk products.
No. It's an independent, buyer-focused assessment that often overlaps with ISO 9001 criteria, but certification is issued by a certification body, whereas an audit is a snapshot report for you.
