Which of the following roles is typically a smaller group of skilled personnel?

The Quality Assurance Team is typically a smaller group of skilled personnel because this team is specifically focused on ensuring that all operations, maintenance, and services meet established standards and regulations. Members of the Quality Assurance Team often possess specialized knowledge and expertise to analyze processes, conduct inspections, and implement quality control measures. This level of expertise necessitates a smaller, more specialized team rather than a larger workforce that might be required for roles like Aircraft Technicians or Maintenance Crews, which involve more hands-on tasks and can often be more numerous in terms of personnel. Quality Assurance roles require precise attention to detail and strong skills in assessing compliance, often leading to a streamlined group of highly trained individuals.
