What does LOE stand for in the context of quality assurance?

In the context of quality assurance, LOE refers to "Line of Evidence." This concept is fundamental in QA as it pertains to the documentation and collection of data that supports decisions about the quality of systems or products. A Line of Evidence typically includes various types of documentation, test results, and other forms of verification that demonstrate compliance with requirements and standards. This establishes a clear understanding of the quality characteristics and allows teams to validate that the product meets its intended use.

Understanding LOE helps quality assurance professionals in making informed decisions based on substantiated data, which can enhance the credibility of the QA process. By systematically gathering this evidence, QA teams can effectively track quality improvements, identify areas for further investigation, and ensure that products are reliable and meet stakeholder expectations. This reinforces the overall quality management system within the organization.
