Which of the following statements is accurate regarding quality assurance techniques?

Quality assurance techniques are fundamentally focused on ensuring that processes, products, and services meet specific standards of quality. The correct statement highlights that these techniques are designed for systematic planning. This systematic approach involves establishing clear procedures, criteria, and standards in order to consistently deliver quality outcomes. Through structured methodologies, quality assurance allows organizations to identify and address potential issues before they affect the final product or service.

In contrast, the other statements do not align with the principles of quality assurance. Random and unstructured approaches would be contrary to the essence of quality assurance, which relies on consistent methods and documented processes. Additionally, while customer service is an important aspect of any organization, quality assurance specifically emphasizes process improvement and compliance with quality standards rather than focusing solely on customer service. Lastly, effective quality assurance techniques should provide measurable outcomes that can be analyzed for improvement, contradicting the notion that they offer no measurable results.
