Which of the following activities is included in quality management?

Quality management in the context of sanitary engineering focuses on ensuring that the processes, goods, and services meet certain standards and fulfill requirements. One of the essential components of quality management is the certification of laboratories and technicians. This process establishes that the individuals and facilities involved in testing and analyzing materials or water quality adhere to recognized standards and practices. Certification ensures that they possess the necessary skills, knowledge, and technical capabilities to conduct tests accurately and reliably, which is integral to maintaining the integrity of quality management systems.

The other activities, while important in their own right for overall project management, do not specifically pertain to the processes of quality assurance and quality control that are central to quality management. Budget allocation planning relates to financial aspects and resource management; site selection assessment is focused on evaluating locations for projects; and construction material procurement deals with sourcing and acquiring materials needed for construction. Thus, laboratory and technician certification stands out as the key activity that directly aligns with the goals of quality management in ensuring compliance with standards and improving reliability in sanitary engineering practices.
