Giacomo has designed a selection system for firefighters. As part of the selection process, firefighters must first complete a job knowledge test. Those who meet the minimum score for the job knowledge test then move on to a physical assessment. After the physical assessment, those who meet the necessary level of fitness move on to a training academy. Those who successfully make it through the academy are hired. What strategy did Giacomo use for this system?
