The correct answer is C. Time and motion studies.
Scientific management is a theory of management that analyzes and optimizes workflows. It was developed by Frederick Winslow Taylor in the late 19th century. Scientific management is based on the following principles:
- One best way: There is one best way to perform any task, and it can be found through scientific study.
- Formalization: Work should be organized and standardized as much as possible.
- Time and motion studies: The time it takes to perform a task should be measured and analyzed in order to find ways to improve efficiency.
- Systematic selection: Workers should be selected based on their skills and abilities, and they should be trained to perform their jobs in the most efficient way possible.
Time and motion studies are not a key concept of scientific management because they are not necessary to find the one best way to perform a task. In fact, time and motion studies can be counterproductive, as they can lead to workers feeling like they are being watched and controlled.
The other options are all key concepts of scientific management. The one best way is the most efficient way to perform a task. Formalization is the process of organizing and standardizing work. Systematic selection is the process of selecting workers based on their skills and abilities.
