Q.Define scientific management. State any three of its principles.

Scientific management is a theory of management that analyses and synthesises workflows, with the objective of improving labour productivity. The core idea is to apply scientific methods to determine the "one best way" to perform a job, replacing the old rule-of-thumb methods. This approach was developed by F.W. Taylor and focuses on efficiency, standardisation, and cooperation between management and workers.

Three key principles of scientific management are:

• Science, not Rule of Thumb: This principle states that every task should be studied scientifically to develop a standard method, rather than relying on the manager's or worker's personal judgement or tradition.
• Harmony, Not Discord: This principle emphasises that there should be complete harmony between management and workers, as both need each other. Management should share the gains of productivity with workers, and workers should work diligently.
• Cooperation, Not Individualism: This principle calls for close cooperation between management and workers to ensure that work is carried out according to the scientifically developed methods. It replaces the old system of individual effort with team-based performance.

Scientific management emerged in the early twentieth century, primarily through the work of American engineer Frederick Winslow Taylor. Taylor observed that workers in factories often worked inefficiently, using outdated methods and deliberately slowing down their pace — a practice he called "soldiering." He believed that the root cause was a lack of systematic knowledge about the best way to perform tasks. Instead of relying on tradition or guesswork, Taylor argued that management should be based on careful scientific study. This meant observing each job, breaking it down into its smallest movements, timing those movements, and then redesigning the work to eliminate wasted effort. The goal was to find the "one best way" to do a job, train workers in that method, and then pay them according to their output.

Scientific management is a philosophy that fundamentally changes the relationship between managers and workers. It is not merely a set of techniques but a complete mental revolution — a shift from conflict and suspicion to cooperation and mutual prosperity. Under scientific management, both sides recognise that their interests are aligned: higher productivity means higher wages for workers and higher profits for employers. This idea of a "mental revolution" is the bedrock upon which all other principles rest.

Three important principles of scientific management are:

• Science, not Rule of Thumb: This is the foundational principle. Instead of relying on personal judgement, tradition, or guesswork (rule of thumb), every task should be studied scientifically. For example, instead of a worker deciding how to shovel coal based on habit, Taylor conducted experiments to determine the optimal shovel load (about 21 pounds) and the most efficient shovel design. This principle demands that management develop a standard method for every job, based on careful observation and measurement.

• Harmony, not Discord: Taylor believed that the traditional industrial relationship was marked by conflict — workers against managers, each trying to get the better of the other. He argued that this was wasteful and counterproductive. The principle of harmony calls for a complete change in attitude. Managers should share the gains of increased productivity with workers, and workers should stop deliberately restricting output. When both sides understand that their prosperity depends on cooperation, conflict dissolves. This is the "mental revolution" in action.

• Cooperation, not Individualism: This principle extends the idea of harmony into the actual work process. Instead of each worker acting independently, there should be close cooperation between management and workers. Management should plan the work, provide the right tools and conditions, and train workers properly. Workers, in turn, should follow the prescribed methods and work to their full capacity. This principle also involves replacing the old system of "initiative and incentive" (where workers are left to figure things out on their own and are rewarded only for results) with a system where management takes on the responsibility of planning and supporting the work.
