Which of the following principles emphasizes the selection of qualified personnel for measurements?

The principle that emphasizes the selection of qualified personnel for measurements is indeed centered around having "the right people" involved in the process. This principle acknowledges that the expertise and skills of individuals who conduct measurements are critical for ensuring accuracy and reliability in data collection and analysis. Qualified personnel bring both technical knowledge and practical experience to the task, which directly impacts the efficacy of the measurement process.

Having the right people means that they are not only trained in the appropriate methods and tools but also understand the standards and ethical implications of their work. Their ability to interpret data correctly and make informed decisions significantly enhances the quality of the measurements taken. This principle recognizes that human factors can greatly influence outcomes, and emphasizing a team of qualified personnel promotes adherence to best practices in measurement.

The other options, while important aspects of any measurement framework, do not specifically address the qualification and expertise of the individuals conducting the measurements. The focus on tools and procedures, while crucial, does not substitute for the necessity of skilled personnel who can apply these tools and procedures effectively.
