Answer:
The correct answer is: Taylor's four scientific management principles.
Explanation:
American economist Frederick Winslow Taylor (1856-1915) in his "The Principles of Scientific Management" (1909) tried to explain that by optimizing and simplifying duties, a firm's productivity could increase. For that purpose, management needed to comply with the following four (4) principles:
1) Science, not the rule of thumb: innovate constantly the process of work.
2) Harmony, not discord: create a proper working atmosphere.
3) Cooperation, not individualism: employees should help each other.
4) Development of each and every person to his or her greatest efficiency and prosperity: match employees' abilities with the duties they will be assigned.
