Science, not rule of thumb ( Scientific principles)

 Scientific principle of management

Frederick Winslow Taylor (March 20, 1856 – March 21, 1915) was an American mechanical engineer. He was widely known for his methods to improve industrial efficiency. He was one of the first management consultants.

Tylor

In 1909, Taylor summed up his efficiency techniques in his book The Principles of Scientific Management which, in 2001, Fellows of the Academy of Management voted the most influential management book of the twentieth century. (Wikipedia) 

There are four scientific principles of management given by F.W. Taylor

1. Science not rule of thumb. (Discussed in this blog)
2. Harmony, not discord.
3. Corporation, not individualism. 
4. Development of workers to their greatest efficiency and prosperity.

Science, not rule of thumb

Science refers to taking action or taking decision on the basis of facts figures and logic.

Rule of thumb refers to taking decision on the basis of personal interest or hit and trial method. The manager chose his approaches based on his prior knowledge. All of these techniques frequently lack scientific validity and testing, and thus cannot be relied upon to produce a certain result.

According to this principal, there should be scientific study and proper analysis of each and every job in the company not just you do anything on the basis of rule of thumb.

Taylor is keen about using cause-and-effect-based scientific procedures to ensure that goals are met as effectively as possible given the time, money, and resources at hand. In light of cause and effect reasoning and scientific measures of the methods, scientific decision-making is therefore prioritised.
