Supervisor

Job Definition and Common Segments Site/Construction Supervisor/Inspector: Keeps an eye on site quality, progress and safety, checks drawings and specifications, signs off on work processes, and organizes acceptance inspections. Quality Inspector/Supervisor: In the manufacturing or supply chain to do incoming materials, process, shipment inspection and disposal of non-conformity, to promote continuous improvement. Safety/Environmental Supervisor (EHS/HSSE Supervisor): Identify risks, organize safety inspections and training, implement incident reporting and rectification of closed loop. Compliance/Audit Officer: Verify system implementation, accounts and records, identify violations and promote correction and prevention. 1. Core Objectives (applicable regardless of direction) Let the standard be truly implemented: quality/safety/regulation/customer requirements to meet the standard. Control risk, ensure delivery: find a balance in the “quality-cost-schedule” triangle. Form a closed loop: Discovery → Record → Rectification → Review → Review and Improvement (PDCA). 1. Main work content (according to PDCA disassembly) Plan Plan: interpretation of specifications / drawings / operating instructions, compilation of inspection plans and sampling program; scheduling inspection routes and frequency. Do implementation: on-site inspection and sampling (size, appearance, process, process witness, PPE, locking and tagging, etc.); photo evidence, immediate communication. Check Inspection: Issue defect/hidden danger list, pass rate statistics of one delivery inspection, and issue rectification notice (NCR/CAR). Act Disposal: Supervise the closed loop, verify the effectiveness; weekly/monthly report, review the reasons for recurrence and update the standard or training. 1. Requirements Hard Skills Familiar with corresponding standards and regulations: e.g. construction specifications, process/drawing reading, measurement and inspection methods, 5Why/fishbone diagram, sampling and statistics (AQL, Cp/Cpk basis), change and acceptance process. System Awareness: Quality (e.g. ISO 9001), Safety/Environment (e.g. ISO 45001/14001) basic logic. Tools: Excel (pivot/conditional formatting), basic data visualization (e.g. Power BI/Looker Studio), project collaboration/work order systems. Soft Skills Communication & Influencing (ability to persuade front line and contractors “with evidence + standards”). Conflict and Negotiation (keep the bottom line without delaying the schedule). Details and ethics (record keeping and traceability). Common Certifications (preferred by orientation) Construction/Supervision: local qualifications such as Registered Supervisor/Supervisory Engineer category, Quality Inspector/Documentation Officer. Safety: NEBOSH/IOSH, local safety certificates; Quality: Six Sigma Yellow Belt/Green Belt, inspector qualifications; Certificates are not required, but can significantly improve competitiveness and promotion speed. 1. Key KPI's and how to quantify results First time pass rate/rework rate Failure rate/defect density, supplier failure rate Hidden defect detection rate, accidents/attempted incidents (TRIR) and corrective closure cycle Inspection coverage, record completeness and punctuality Recurrence rate of quality/safety issues (continuous improvement effectiveness) Example of quantitative sentence to write in resume or review “Established AQL sampling program to reduce shipment defect rate from 1.8% to 0.6%, saving ¥×× million in rework costs quarterly.” “Optimized inspection routes and frequency, reducing the median corrective closure cycle from 5 days to 2 days.” 1. One-Day Workflow (Sample) Morning Meeting (Risk Alert/Operation Plan) → Key Process Witnessing & Sampling → Recording & Forensics → Afternoon Re-inspection/Contractor Alignment Meeting → Data Updates & Daily/Weekly Reports → Training or Special Audits. 1. Common Difficulties and Solutions Conflict of “wanting progress but not quality/safety”: persuade with standard clauses + risk consequences + cost of resumption of work; escalation mechanism if necessary. Inadequate record-keeping: Unified template (photo + time + coordinates / work point + responsible person), electronic ledger. Recurrence of the problem: cause and effect analysis of “man/machine/materials/law/environment”, distinguishing between one-time mistakes and systematic defects. Multiple work sites and multiple shifts: Prioritization matrix (risk x impact x urgency) + Spot-check coverage Kanban. 1. Interview High Frequency Questions and Answer Ideas (STAR) Tell us a case where you insisted on the standard but did not delay the deadline (How to resolve the conflict? How to quantify the result?). How do you quantify results?) How do you design a sampling program & determine sample size? (AQL/historical defect data/process energy) Translated with DeepL.com (free version)
