Final answer:
Scientific management, introduced by Frederick Taylor, focused on economic efficiency and labor productivity through careful worker selection, training, and supervisory support.
Step-by-step explanation:
The management style that emphasized careful selection and training of workers and supervisory support is scientific management. This approach, spearheaded by mechanical engineer Frederick Taylor, also known as "stop-watch management," was focused on improving economic efficiency and labor productivity.
It involved decomposing manufacturing tasks into short, repetitive segments, which were carefully timed and standardized to maximize efficiency. Training and development of the workforce were crucial components, enabling employees to offer the highest quality of work and thus meet not only the company’s goals but also foster the best outcomes for the employees.
The goal of scientific management, as Taylor defined it, was profit maximization for the employer coupled with the optimal outcome for the employees. This management theory played a substantial role in the formation of industrial psychology, which examines management theories, personnel selection, training, and the work itself through time and motion studies.
