What type of data is generally documented during proof-of-performance tests?

The documentation during proof-of-performance tests primarily includes test procedures and results. This type of data is critical as it provides a detailed account of how the test was conducted and the outcomes achieved, ensuring that the performance meets the required standards and specifications. Documenting test procedures allows for consistency and repeatability in testing, and capturing results provides evidence that can be analyzed to verify compliance with performance benchmarks. This thorough documentation is essential for quality assurance and can be used to support claims about the equipment or system's reliability and functionality.

While unverified reports, anonymous feedback, and customer complaints may provide some insights, they do not offer the structured and formally accepted documentation needed to evaluate performance effectively.
