Meaning
Audit procedures assess the physical machine assets, labor force, and raw material throughput of sub-tier component suppliers. Conducting tier 2 capacity verification ensures secondary vendors can meet the volume requirements demanded by primary assembly plants during peak production schedules. Primary suppliers frequently overestimate sub-tier capability, leading to component bottlenecks and assembly line shutdowns.
Independent verification inspects secondary facility floor space, machine cycle times, shift staffing levels, and utility access to calculate true maximum daily output.
Onsite Audit
Technical audit teams evaluate floor machinery nameplates, maintenance records, and power draw logs at sub-tier supplier facilities. Performing tier 2 capacity verification requires validating actual machine run-rates against claimed factory output figures. Auditors review raw material purchase orders and worker attendance records to verify operational readiness during peak seasonal demand.
Bottleneck Analysis
Identifying sub-tier production constraints prevents unexpected component delivery delays at primary assembly factories. Conducting tier 2 capacity verification reveals machine maintenance backlogs, missing backup power generators, and single-source raw material dependencies. Secondary component constraints constrain overall assembly line output regardless of primary factory size.
Supply Risk
Phantom capacity claims collapse when sub-tier suppliers accept competing orders from multiple primary vendors. Regular physical audits establish actual production limits and protect foreign buyer production schedules.
