I. Factory Audit Process
What to look for in the factory audit process? Based on third-party audit practices, the process is viewed through these aspects: Four Stages—the process is divided into four stages (requirement confirmation, gap assessment and remediation, documentation and system preparation, and on-site audit and follow-up; each stage has clear deliverables and criteria);
Timeline—it takes an average of 4 to 8 weeks of preparation for a factory that has never undergone an audit to pass one after receiving the client’s notification; Application—the application and preparation phase (the enterprise contacts a third-party agency to submit audit requests and confirm standards); Planning—developing the audit plan (the third-party agency schedules the audit time and scope based on business needs); Scope—defining the audit scope (determining coverage—such as production sites and warehouses—based on the supplier’s services and product types); Objectives—clarifying audit goals (verifying whether the supplier meets company requirements regarding quality management, production efficiency, and employee operational standards); Duration—typical timeline for auditing a factory in China (2–4 weeks for pre-audit preparation; 4–16 hours or 1–2 days for on-site or remote assessment; 1–3 weeks for the post-audit report). In summary, the process involves six key aspects: the four-stage division, the 4–8 week cycle, application confirmation, scheduling, scope and objectives, and the audit timeline.
II.
Documentation Preparation
What to look for regarding documentation preparation?
Based on practical experience in preparing for factory audits, here is how to review the documentation: Qualifications—collect business licenses, production permits, quality management system certificates (e.g., ISO 9001), and relevant industry qualifications from new suppliers in advance; Verification—immediately verify the validity of the materials received (check if certificates are current and if the certification scope covers the actual business activities—for instance, an ISO 9001 scope specifying “metal stamping” would not match an order for “injection-molded parts”); Records—gather the supplier’s internal testing records and third-party test reports from the past year; Documentation—conduct a preliminary review of documents such as the business license, quality management system files, production records, and employee handbooks; System—organize the documentation system (refine the quality manual to clearly define quality policies, objectives, system scope, and processes; prepare procedural documents covering raw material inspection, production process control, finished product inspection, and non-conforming product handling); Records—compile quality records such as raw material inspection reports, in-process inspection logs, and final inspection reports for finished products; Checklist—address the list of documents requested by the auditor (e.g., corporate qualifications, production flowcharts, staffing charts, quality management manuals, and environmental management policies). In summary, the documentation review covers six key areas: qualifications, certificate verification, testing records, system documents, procedural documents, and quality records.
III.
On-site Audit
What to look for during the on-site audit.
Based on practical experience with on-site factory audits, the on-site process involves the following: Opening Meeting (auditors hold a brief meeting upon arrival—requiring the attendance of the factory manager and supervisors/managers responsible for production, HR/payroll, and safety—to understand the factory layout, including workshops, warehouses, and dormitories; introduce the audit’s purpose, methodology, and schedule; list required documents; and explain the worker interview process); Eight-Step Structure (the standard audit framework covering the opening meeting—scope, methodology, timeline, and agreement on areas to visit and personnel to interview—document review, and facility walkthrough); Facility Walkthrough (covering raw material storage, production workshops, QC laboratories, finished goods warehouses, maintenance areas, and waste disposal zones, with photo documentation and observation notes for each area); Document Review (checking business licenses, quality manuals, training records, equipment calibration certificates, payroll records, time cards, social security payment receipts, safety drill logs, environmental permits, and subcontractor agreements); Worker Interviews (conducting interviews with employees regarding social responsibility, often visiting the canteen during meal times or dormitories during lunch breaks to gain a more authentic understanding); Full Escort (company system personnel and quality management staff accompany the auditors throughout the process to answer questions promptly); and Photography (some clients require photos for their records). In summary, the on-site audit comprises six key elements: the opening meeting, the eight-step structure, the facility walkthrough, document review, worker interviews, and full escort accompaniment.
IV.
Audit Content
What is covered in the audit?
Based on factory audit practices, the scope covers six key areas: Quality—Quality Management System (QMS) certification audit in two stages (Stage 1: document review to verify compliance with standards and completeness of trial run/internal audit records; Stage 2: on-site audit involving record reviews, personnel interviews, and on-site observations to verify actual system implementation; ISO 9001 certification process); Manufacturing—Manufacturing process audit (evaluating the effectiveness of all manufacturing processes; auditing each process at a frequency commensurate with its risk; using process-specific checklists covering inputs, controls, outputs, and records; iFactory IATF 16949 checklist); Product—Product audit (checking product compliance with customer requirements; sampling and inspecting against engineering specifications at appropriate production or delivery stages; iFactory); System—System audit (evaluating the entire QMS against all IATF 16949 clauses and applicable customer-specific requirements; The Standards Navigator); APQP—APQP Phase 2 audit (process audit comparing each manufacturing process against PFMEA, control plans, and work instructions; product audit involving sampling production parts to check dimensional and functional compliance; system audit; The Standards Navigator); Risk—Risk-driven audits (determining if the supplier can maintain the process capability claimed in the PPAP; IATF 16949 explicitly expects second-party audits as part of supplier monitoring and development; audit planning based on risk, product safety, and supplier performance; beefed.ai); Layered—Layered Process Audit (evaluating compliance with standardized processes and identifying opportunities for continuous improvement; involving employees at different levels, including top management, in the audit hierarchy; IATF 16949/GM CSR)—Summary of the six areas: QMS two-stage audit, manufacturing process audit, product audit, system audit, risk-driven approach, and layered process audit; a comprehensive scope.
V.
Follow-up on Corrective Actions
What to look for during corrective action follow-up.
Based on practical experience with factory audit remediation, the process is viewed through these categories: **Rating**—classifying findings by severity after the audit; **Critical**—critical non-conformities (e.g., missing quality management systems, key product indicators exceeding limits, expired production licenses, direct wastewater discharge without treatment facilities; recommendation: immediately reject the new supplier and halt cooperation); **General**—general non-conformities (e.g., incomplete inspection records, material labeling needing standardization, missing document approvals; requirement: supplier must remediate within a specified timeframe, usually 15–30 days); **Major**—major non-conformities (e.g., complete absence of required processes or systemic collapse; certification halted pending resolution; requires root cause analysis, corrective actions, and evidence, usually within 90 days); **Minor**—minor non-conformities (e.g., isolated oversights or single instances of non-compliance; conditional certification; requires corrective action plan and evidence, usually within 90 days); **Observation**—observations or opportunities for improvement (areas of interest not yet reaching non-conformity levels; does not affect certification decisions; no formal response required); **CAP**—post-audit reporting phase (drafting reports, internal quality review, issuing CAP, submitting for review); **Re-audit**—remediation and re-verification (enterprise must implement corrective actions for audit findings)—**Six Perspectives on Remediation**: classification/rating, critical rejection, general (time-limited), major (90-day window), minor correction, and re-audit/closure;
these six perspectives ensure reliable remediation.
Conclusion
What is the factory audit process for automation equipment components? The conclusion is: a five-dimensional standard covering process, documentation, on-site conditions, audit content, and remediation.
The process comprises four stages—requirement confirmation, gap assessment and remediation, documentation and system preparation, and on-site audit and follow-up—along with application review, planning, and defining objectives and scope. Preparation typically takes 4–8 weeks for factories new to the process, with 1–2 days for the on-site audit and 1–3 weeks for the report. Documentation requirements include business licenses, production permits, and ISO 9001 certificates (verified for validity and scope); internal and third-party test reports from the past year; quality manuals and procedural documents (covering raw material inspection, production process control, finished product inspection, and non-conforming product handling); and quality records. On-site activities involve an opening meeting (attended by the factory director and managers), facility walkthroughs (raw material storage, production workshops, QC labs, finished product warehouses, maintenance areas, and waste disposal zones), document reviews, employee interviews, and photography for documentation purposes. The audit content covers quality management (two-stage audit), manufacturing processes (checked against PFMEA and control plans), products (sampling against engineering specifications), and the overall system (checked against all clauses), incorporating risk-based approaches and layered audits. Remediation protocols address various findings: “critical non-conformities” (such as missing system elements, exceeded limits, or expired permits) may lead to immediate rejection; “general non-conformities” require rectification within 15–30 days; “major non-conformities” require root cause analysis, corrective action, and evidence submission within 90 days; and “minor non-conformities” require a corrective action plan, followed by a review to ensure closure.
In summary, the factory audit process boils down to this: confirm standards and verify qualification validity; conduct on-site inspections and interviews; and ensure remediation is closed out with documented proof.
Clear these four hurdles, and the audit process will proceed smoothly.
