Request daily production monitoring before production starts when a new supplier, changed product, complex assembly, or mixed-SKU schedule needs day-by-day checks. If production is already running, request it when repeat defects, line changes, or high output make the gap between stage inspections too large. Agree the first attended day while the relevant production is still accessible; do not wait until final inspection to investigate a problem developing during the run.
We are UTS, a third-party inspection company providing product inspection, factory audit, supplier evaluation, and laboratory testing coordination. The timing guidance below is general information for buyers and suppliers, separate from our inspection reports.
When Output Outruns the Visit Schedule
Compare planned daily output with the interval between visits. In a hypothetical schedule producing 2,000 units a day, a five-day interval represents about 10,000 units produced between checks. This is schedule arithmetic, not a sample size or an affected quantity. Request daily monitoring if that amount of production without intermediate inspection evidence exceeds the gap you are prepared to accept.
A single visit establishes findings within its own scope; it does not, by itself, establish when a defect began or whether later output has the same problem. Daily visits provide additional dated observations, not continuous surveillance or verification of every unit. Agree which lines, shifts, and SKUs need coverage rather than assuming one visit covers all daily production.
When the Supplier or Product Is New
A first order alone does not automatically require daily monitoring. Request it when there is an unresolved question that needs checking as production progresses: whether the factory is using the approved revision, whether a changed component matches the specification, or whether early workmanship remains consistent on subsequent output.
Before production, a Factory Evaluation examines the site and production capability within the agreed audit scope. A Sample Evaluation checks samples against the product requirements. Neither establishes the condition of goods manufactured later. If the concern relates to repeated output rather than the initial sample or factory setup, plan monitoring during the relevant production days.
When Defects Reappear
Request daily monitoring when an earlier check finds a recurring defect and you need evidence from subsequent production. Confirm which product, line, and production dates are involved. Do not wait for the same fault to appear in a specified number of cartons: the decision depends on the defect and the agreed product requirements, not a universal carton-count trigger.
Keep original findings separate from checks on reworked goods. For example, a hypothetical record of 6 affected units out of 120 checked on one day and 1 out of 120 on another describes those checks only. Before treating the difference as a trend, compare the SKU, defect definition, selection method, and test conditions. Different products or scopes can produce counts that are not directly comparable; the figures do not prove a lot-wide improvement or establish the cause.
When Assembly or SKU Coverage Changes
Consider daily monitoring when different component versions, assembly steps, models, colors, or packing files enter production on different days. Request attendance for the days when the relevant versions or SKUs will actually be available. An order-wide completion percentage can hide a model that has barely started.
Our published inspection approach checks goods against the PO, specification, approved sample, drawings, and packing files. For multi-SKU orders, our reports identify which SKUs were sampled and how many units were checked. Applied to a monitoring scope, those fields help buyers distinguish evidence for one model from evidence for another. They do not confirm every assembly step or all output on an unattended shift.
When Schedules or Lines Change
Reassess the visit plan when additional shifts, another line, subcontracted work, or a compressed schedule changes where and when the order is made. Ask the supplier for the revised production dates, locations, line allocation, and daily quantities. Request additional daily coverage where those changes leave the relevant output outside the existing inspection plan.
Agree access before attendance. If a location, shift, or process cannot be checked, that limitation must remain explicit; it cannot be treated as completed coverage. Daily monitoring is useful only where the agreed checks can actually be performed. Where output is limited, adjust attendance to the available production instead of claiming a full daily scope from insufficient goods.
When Stage Inspections May Be Enough
Stage inspections may be sufficient for a stable repeat product when specifications are current, the relevant SKUs will be available at each visit, and no unresolved quality issue calls for closer follow-up. A small order or a familiar supplier is not, by itself, evidence that daily monitoring is unnecessary.
| Inspection option | UTS timing reference | Decision use |
|---|---|---|
| Initial Production Inspection | About 5% to 10% produced | Check early output against the agreed requirements |
| During Production Inspection | About 30% to 50% produced | Check goods while production continues |
| Final Random Inspection | 100% produced with at least 80% packed | Check finished goods before shipment |
| Daily monitoring | Agreed production days requiring closer coverage | Obtain dated findings between or around stage inspections |
These are UTS service timing references, not universal thresholds for requesting monitoring. Daily attendance does not replace final inspection or a separately agreed Full Inspection scope. Buyers can reduce attendance when the concerns that prompted it have been addressed and subsequent comparable findings support returning to stage checks; agree the remaining inspection scope explicitly.
What to Agree Before Attendance
Product and Sampling Scope
Send the PO, order quantity, SKU breakdown, production schedule, factory address, approved sample and revision, drawings, tolerances, defect criteria, and packing files with the request. Identify the question each attended day should address. You can make the initial request before every detail is settled; finalize the scope, access, and available goods before the visit.
Our team works to the buyer-approved inspection level and sampling plan. ISO 2859-1 provides AQL-indexed sampling schemes for inspection by attributes.[1] Where the order specifies that standard or ANSI/ASQ Z1.4, confirm the applicable edition and plan rather than assuming the standards are interchangeable. Agree which goods constitute the lot for each sampled check; a daily visit schedule does not itself define a sampling plan.
Tests and Access
Confirm attendance dates, working hours, line and carton access, available test equipment, and the on-site tests that can be performed. Our published process includes agreed function checks and simple on-site tests where the factory has the required setup. We coordinate laboratory testing separately where the product or market requires tests that cannot be performed on site.
Where barcode or QR-code scanning is included, agree the scanner, setup, and test conditions, and compare encoded information with the approved data. The scan-success requirement is 100% for the checked codes under those conditions. Record the checked scope and any failures. This does not mean every code in the order was checked or that the codes will read on every other device.
What Daily Findings Can Establish
Our published report content includes defects, measurements, on-site test results, quantity status, packaging checks, and photo evidence. ISO/IEC 17020 specifies requirements for the competence, impartiality, and consistent operation of inspection bodies; citing that standard is not a claim that a particular order has passed inspection.[2]
Our reports present actual findings only. They describe what was checked and found; they do not contain recommendations, corrective-action plans, improvement suggestions, or advice to accept, rework, or ship the goods.
For monitoring, agree that dated findings identify the relevant SKU, checked quantity, and scope so that the buyer can compare like-for-like results. Later findings do not erase earlier defects, and checks on reworked goods do not establish the condition of unchecked production. Decisions about holding, sorting, reworking, additional testing, or shipment remain with the buyer and supplier under the applicable requirements.
When to Send the Request
Send the request as soon as you identify a need for evidence between stage inspections: during planning for a changed or complex order, or promptly after a recurring defect or production-plan change. State the concern and the next relevant production date. Confirm attendance before that output becomes inaccessible, without assuming a fixed booking lead time or automatic team availability.
Share your production schedule, SKU breakdown, and the issue you need checked. Our team can discuss the monitoring scope and available attendance dates.
