| Relevant Product Experience | At least 3 years of experience producing wearable devices or closely related consumer electronics. | Review dated product records, technical documentation, sample history, and export references with sensitive details removed. | Only generic catalog images, unclear product ownership, or no evidence of continuous production. | 10% |
| Production Capacity | A documented monthly capacity of approximately 10,000 units or more for the relevant product category, with scalable assembly resources. | Request capacity by production line, staffing level, shift pattern, and current utilization rather than relying on a general claim. | Capacity is stated only as an annual figure or depends entirely on subcontractors. | 10% |
| Quality Management | A documented quality system, incoming inspection, in-process inspection, final inspection, and traceable corrective-action records. | Audit the quality manual, inspection plans, sampling rules, calibration records, and nonconformity reports. | Quality checks are performed only at the end of assembly or cannot be documented. | 15% |
| Water and Sweat Resistance | The claimed protection level should be supported by a defined test method, sealed enclosure design, and batch-level verification. | Check laboratory reports, pressure or immersion test procedures, gasket specifications, and the exact model configuration tested. | A water-resistance claim is made without test conditions, limitations, or model-specific evidence. | 10% |
| Sensor and Sports Data Capability | The product should support documented accuracy testing for heart rate, motion tracking, step counting, sleep-related metrics, or other advertised functions. | Request test protocols, comparison methods, firmware version records, and known limitations for each advertised metric. | Marketing claims exceed the available validation data or use medical wording without appropriate regulatory support. | 15% |
| Battery and Charging Performance | Battery life should be reported under defined usage conditions, with protection circuits and cycle-testing procedures in place. | Compare laboratory runtime with real-use testing and review battery cell specifications, charging tests, and safety controls. | Battery duration is quoted without screen, GPS, Bluetooth, notification, or measurement conditions. | 10% |
| Firmware and Mobile Application | Stable firmware, documented update procedures, multilingual support, data synchronization, and a defined bug-fixing process. | Test the app on target operating systems and request release notes, software support terms, data-flow documentation, and issue-response records. | The app is unfinished, updates are uncontrolled, or the supplier cannot explain data storage and access practices. | 10% |
| Compliance and Market Access | The supplier should identify applicable radio, electrical, battery, chemical, and packaging requirements for the destination market. | Verify model-specific test reports, declarations, battery transport documents, labeling, and user-manual requirements. | Certificates belong to another model, contain inconsistent specifications, or cannot be independently verified. | 15% |
| Customization and Tooling | Clear engineering support for logo, enclosure, strap, display, packaging, firmware, and user-interface customization. | Request a development schedule, tooling ownership terms, prototype stages, engineering-change process, and sample approval criteria. | Customization is promised without drawings, samples, engineering fees, or an agreed approval process. | 5% |
| Supply Chain and Component Control | Critical components should have approved alternatives, lot traceability, change notification, and continuity planning. | Review the bill of materials, approved-vendor list, component change procedure, and shortage response plan. | Unapproved substitutions are common or component specifications are not disclosed before production. | 5% |
| After-Sales Support | A written warranty, spare-parts policy, return procedure, response-time target, and long-term firmware-support commitment. | Review the warranty terms, escalation contacts, replacement process, technical-support language, and service-level expectations. | Support ends after shipment, warranty exclusions are broad, or no responsible technical contact is assigned. | 5% |
