Frederick Winslow Taylor introduced the concept of Scientific Management in the starting of 20th century in the USA. The concept was further carried out by Frank, Lillian Gilbreth, and Henry Gantt.
The concept was developed to enhance the operational efficiency at the shop floor level. It refers to knowing exactly what you want your employees to do and then examine that they do it in the best and the cheapest way.
Scientific management is an art of understanding exactly what needs to be done and how it can be done. When an organization is following this approach, various scientific techniques are used in the recruitment, selection, and training of the work force. These techniques are also used in handling numerous industrial problems.
