Who is responsible for tracking controlled materials in quality assurance processes?

The responsibility for tracking controlled materials in quality assurance processes lies with the Quality Assurance Officer (QAO). This role involves overseeing the quality assurance program, ensuring that all materials used meet specified standards and are properly documented throughout the project lifecycle. The QAO plays a critical role in monitoring compliance with regulations and procedures related to controlled materials, making them the central figure in maintaining quality standards.

While other options like the Quality Assurance Inspector (QAI) and Craftsman may contribute to the oversight of quality materials, their roles typically focus on inspection and quality checks, rather than on systematic tracking and documentation. The Control Material Purchase Order (CMPO) refers to the procedures or documents used to acquire those materials, rather than the personnel involved in the quality assurance process. Thus, it is not the appropriate choice for responsibility in tracking controlled materials.
