The correct answer is: A. maximisation of productivity.
Scientific management is a theory of management that analyzes and optimizes workflows. Its main goal is to increase productivity by standardizing tasks and processes, and by using scientific methods to study and improve work methods.
Scientific management was developed by Frederick Winslow Taylor in the late 19th and early 20th centuries. Taylor believed that the best way to improve productivity was to break down complex tasks into their component parts, and then to study each part in detail to find ways to improve it. He also believed that it was important to train workers in the most efficient methods of performing their tasks.
Scientific management has been criticized for its focus on efficiency at the expense of worker satisfaction. However, it has also been credited with helping to improve productivity in many industries.
Option B, maximisation of employment, is not the overall goal of scientific management. Scientific management is not concerned with increasing the number of employees, but with increasing the productivity of the employees who are already working.
Option C, higher industrial efficiency, is a goal of scientific management, but it is not the overall goal. The overall goal of scientific management is to maximize productivity.
Option D, greater profit to producer, is not the overall goal of scientific management. Scientific management is not concerned with increasing the profits of the producers, but with increasing the productivity of the employees.
