Factory audits reveal supplier capabilities beyond polished presentations. Discover 12 critical observation points covering equipment condition, quality systems, workforce stability, and operational discipline.

Factory audits separate capable suppliers from those presenting polished showrooms whilst hiding operational deficiencies. A single day observing production reveals more about manufacturing capability, quality systems, and reliability than months of email exchanges and sample evaluations.
Experienced auditors look beyond clean floors and organised warehouses toward operational indicators predicting long-term performance. Equipment condition, worker behaviour, material handling practices, and documentation systems expose truths that supplier presentations carefully obscure.
Equipment state reveals investment priorities and operational discipline. Well-maintained machinery indicates management valuing quality and efficiency whilst neglected equipment suggests cost-cutting compromising capability.
Die-cutting press condition provides immediate capability assessment. Inspect cutting platens for wear patterns, scoring, or unevenness—damaged platens cause inconsistent cutting pressure producing variable edge quality. Check blade holders for looseness or damage preventing secure blade mounting. Examine drive systems for unusual noise, vibration, or oil leaks indicating deferred maintenance.
Printing equipment cleanliness correlates with colour consistency. Ink buildup on rollers, doctor blades, or impression cylinders indicates inadequate cleaning between jobs—a primary cause of colour contamination and variation. Suppliers maintaining spotless printing equipment demonstrate discipline translating to consistent output quality.
Preventive maintenance records distinguish reactive from proactive operations. Request maintenance logs showing scheduled servicing, parts replacement, and calibration activities. Comprehensive records with regular entries indicate systematic maintenance whilst sparse documentation suggests running equipment until failure. This difference predicts downtime frequency and quality consistency.
Equipment age matters less than condition and capability. A 15-year-old press receiving regular maintenance and upgrades often outperforms a 5-year-old machine operated carelessly. However, extremely old equipment lacking modern controls limits process capability regardless of maintenance quality. Assess whether equipment vintage prevents achieving required tolerances or throughput.
How suppliers handle raw materials and work-in-process reveals quality consciousness and contamination risks. Proper material management prevents defects whilst poor practices introduce problems even excellent equipment cannot overcome.
Paperboard storage conditions directly affect dimensional stability and printability. Check storage areas for climate control—temperature and humidity variations cause paperboard expansion and contraction creating registration problems during printing and die-cutting. Observe whether materials rest on pallets preventing ground moisture absorption and whether plastic wrapping remains intact protecting against humidity.
Material rotation systems prevent age-related degradation. FIFO (first-in-first-out) inventory management ensures older stock ships before newer arrivals. Look for date coding on material packages and observe whether warehouse layout facilitates FIFO flow. Random stacking without organisation suggests poor inventory control risking shipment of degraded materials.
Work-in-process protection between operations prevents contamination and damage. Printed sheets awaiting die-cutting should rest in covered carts or racks preventing dust accumulation and surface scratching. Observe whether workers handle sheets by edges avoiding fingerprints on printed surfaces. These small practices accumulate into significant quality differences.
Waste segregation indicates cost consciousness and environmental responsibility. Separate collection of paper waste, plastic strapping, and defective products suggests systematic operations whilst mixed waste piles indicate disorganised processes. Waste management discipline correlates with overall operational discipline affecting quality and efficiency.
Worker capability and retention determine whether suppliers can consistently execute complex requirements. High turnover and inadequate training create quality variability regardless of equipment capability.
Observe worker-equipment interaction during production. Skilled operators make continuous micro-adjustments maintaining optimal performance whilst inexperienced workers run equipment without intervention until problems become obvious. Watch for operators checking output quality, adjusting settings, and responding to process variations—these behaviours indicate competence and engagement.
Training documentation reveals investment in workforce development. Request records showing new hire training programs, skill certification, and ongoing education. Suppliers maintaining comprehensive training systems develop capable workforces whilst those relying on informal on-the-job learning produce inconsistent results.
Worker tenure provides retention insights. Ask supervisors about average employee tenure and turnover rates. High turnover—above 30-40% annually—indicates workplace issues undermining quality through constant workforce churn. Stable workforces accumulate experience translating to better quality and efficiency.
Compensation practices affect retention and motivation. While specific wage levels remain confidential, observe whether facilities offer amenities—cafeterias, rest areas, transportation—indicating worker welfare investment. Suppliers treating workers as disposable resources struggle with retention and quality.
Quality systems separate suppliers catching defects before shipment from those discovering problems through customer complaints. Systematic inspection and documentation predict reliability better than any capability claims.
In-process inspection frequency and methods reveal quality priorities. Observe whether operators perform regular checks or run production continuously without verification. Check for inspection stations between process steps—printing to die-cutting, die-cutting to finishing—catching defects before value-adding operations continue. Absence of in-process inspection suggests quality verification happens only at final inspection when defects are costly.
Inspection equipment calibration ensures measurement accuracy. Request calibration certificates for measuring tools—micrometers, colour spectrophotometers, gloss meters—used in quality verification. Current calibration (within past 12 months) indicates measurement discipline whilst expired or absent calibration suggests measurements lack validity.
Defect tracking systems provide quality trend visibility. Ask to see defect logs showing types, frequencies, and root causes of quality issues. Detailed records with corrective actions indicate systematic quality management whilst absent or superficial documentation suggests reactive firefighting without improvement focus.
Statistical process control implementation demonstrates advanced quality management. Look for control charts posted at workstations showing process parameters and variation trends. SPC adoption indicates suppliers managing processes proactively rather than just inspecting output reactively.
How suppliers plan and schedule production affects delivery reliability and rush order accommodation. Sophisticated planning systems enable reliable commitments whilst chaotic scheduling creates constant firefighting.
Production scheduling visibility indicates planning maturity. Request to see production schedules showing current and upcoming jobs. Detailed schedules extending 4-6 weeks ahead with material requirements and capacity allocation demonstrate planning discipline. Vague schedules or reluctance to share planning information suggests disorganised operations.
Capacity utilisation levels affect flexibility and delivery reliability. Suppliers running at 85-95% capacity have little flexibility for rush orders or schedule changes whilst those at 60-70% can accommodate variations easily. However, very low utilisation raises questions about business viability and competitiveness. Optimal utilisation balances efficiency with flexibility—typically 75-85%.
Material planning systems prevent shortages disrupting schedules. Ask how suppliers forecast material requirements and trigger procurement. Formal MRP (Material Requirements Planning) systems calculate needs based on production schedules whilst informal systems rely on visual inspection and experience. Systematic approaches reduce shortage risks.
Schedule adherence metrics reveal delivery reliability. Request data showing on-time completion rates for recent production. Suppliers consistently achieving 90%+ on-time completion demonstrate planning and execution capability whilst those below 80% struggle with schedule reliability regardless of capacity.
Financial health affects long-term viability and investment capability. Suppliers facing financial stress cut corners, defer maintenance, and may disappear mid-contract.
Facility investment and maintenance indicate financial health. Well-maintained buildings, modern equipment, and ongoing improvements suggest profitable operations reinvesting in capabilities. Deferred maintenance, aging equipment without replacement plans, and deteriorating facilities raise financial stability concerns.
Payment term requests provide financial stress signals. Suppliers demanding large deposits or shortened payment terms may face cash flow problems. While deposits are reasonable for custom tooling or materials, excessive advance payment requirements suggest financial difficulties.
Workforce payment practices reveal cash flow status. Delayed salary payments or reduced benefits indicate financial stress affecting worker morale and retention. While direct inquiry about payment practices may prove difficult, worker attitudes and turnover provide indirect indicators.
Expansion activities demonstrate confidence and investment capability. Suppliers adding capacity, upgrading equipment, or expanding facilities signal financial health and growth expectations. Stagnant operations without investment raise questions about profitability and long-term viability.
Compliance with environmental and labour regulations affects supply chain risk and brand reputation. Non-compliant suppliers create legal and reputational exposure regardless of product quality.
Waste treatment systems indicate environmental responsibility. Check for wastewater treatment facilities handling coating and ink waste rather than direct discharge. Observe air filtration on coating ovens and printing equipment preventing VOC emissions. Absence of pollution controls suggests regulatory non-compliance creating supply chain risks.
Chemical storage and handling practices affect worker safety and environmental protection. Inspect chemical storage areas for proper labelling, containment, and ventilation. Observe whether workers handling chemicals wear appropriate protective equipment. Poor chemical management indicates safety and environmental risks.
Labour practice compliance requires careful observation. While overt violations like child labour are rare in established suppliers, excessive overtime, inadequate safety equipment, or poor working conditions create risks. Observe worker ages, safety equipment usage, and working environment conditions during facility tours.
Certification status provides third-party compliance verification. Request copies of ISO 9001 (quality management), ISO 14001 (environmental management), and social compliance certifications like BSCI or Sedex. Current certifications with recent audit dates indicate ongoing compliance whilst expired or absent certifications raise concerns.
Existing customer relationships reveal supplier performance better than any self-promotion. Long-term customers indicate satisfactory performance whilst high customer churn suggests problems.
Request customer references and contact them directly. Ask about quality consistency, delivery reliability, communication responsiveness, and problem resolution. Multiple positive references from long-term customers provide strong capability validation whilst reluctance to provide references raises red flags.
Customer retention rates indicate satisfaction levels. Suppliers retaining customers for 3-5+ years demonstrate consistent performance whilst those constantly replacing customers suggest quality or service issues. Ask about longest-standing customer relationships and reasons for any major customer losses.
Order size progression reveals customer confidence. Customers increasing order volumes over time demonstrate satisfaction and trust whilst declining volumes suggest problems. Request examples of customer relationships showing volume growth as evidence of performance quality.
Repeat business percentage indicates customer satisfaction. Suppliers deriving 60-70%+ revenue from repeat customers demonstrate reliability whilst those constantly seeking new customers to replace departing ones face retention issues. High repeat business correlates with consistent quality and service.
How suppliers communicate during audits predicts ongoing relationship quality. Transparent, responsive communication indicates partnership orientation whilst evasive or delayed responses suggest problems.
Question response quality reveals transparency. Direct answers with supporting data demonstrate confidence and honesty whilst vague responses or deflection suggest hiding problems. Observe whether suppliers readily share information or require repeated requests.
Problem acknowledgment indicates maturity. Suppliers openly discussing past quality issues and corrective actions demonstrate learning orientation whilst those claiming perfect records lack credibility. Honest problem discussion with improvement evidence builds confidence.
Technical knowledge depth affects problem-solving capability. Engage technical staff in discussions about processes, materials, and quality challenges. Deep technical understanding enables effective problem resolution whilst superficial knowledge limits improvement capability.
Follow-up commitment reliability predicts ongoing responsiveness. Note commitments made during audits—providing additional information, sending samples, clarifying specifications—and track whether suppliers deliver as promised. Failure to follow through on audit commitments predicts poor ongoing communication.
Current capacity and expansion potential affect long-term partnership viability. Suppliers unable to grow with your requirements force eventual re-sourcing disruption.
Equipment count and shift utilisation reveal capacity headroom. Count major equipment pieces and observe shift patterns. Single-shift operations offer easy capacity expansion through additional shifts whilst three-shift operations require equipment additions for growth.
Facility space availability enables expansion. Observe whether production areas appear crowded or include empty space for additional equipment. Suppliers operating in cramped facilities face expansion limitations whilst those with available space can add capacity readily.
Growth plans and investment intentions indicate scalability. Discuss supplier expansion plans and capital investment budgets. Suppliers planning equipment additions or facility expansion can support volume growth whilst those without growth plans limit partnership potential.
