What percentage of verification testing (VT) is typically carried out?

The typical percentage of verification testing (VT) carried out is often set at 25%. This standard reflects an industry practice where a significant portion of activities are monitored to ensure compliance with quality specifications and standards. Verification testing serves as a crucial tool in the quality control process, allowing managers to assess the accuracy and reliability of production or construction processes. The 25% standard strikes a balance between thorough oversight and efficiency, providing enough data to evaluate performance while not overwhelming resources with excessive testing. In the context of quality control, adhering to this percentage helps ensure that projects meet the required quality thresholds without incurring unnecessary delays or costs associated with more intensive sampling.
