In situations where there is a dispute regarding the quality of project deliverables, it is essential to provide evidence that demonstrates adherence to quality standards. Showing the customer the quality control measurements is an effective way to communicate that the project outputs have been produced according to the agreed-upon quality requirements. This approach is supported by the PMI's distinction between quality assurance and quality control. Quality control involves the technical processes that examine, analyze, and report the project's progress and conformance with performance requirements. By sharing the quality control measurements, the project manager can provide objective evidence that the project deliverables meet the necessary quality standards1.
