Scientific Management

Scientific management is a theory of management that analyses and

synthesizesworkflow. Its main objective is to improve economic

efficiency, especially in labour productivity.

It was actually one of the earliest attempts of applying science to theengineering of process and management.

It was developed by Frederick Winslow Taylor between 1880s and

1890s within the manufacturing industries.

According to Fredrick Winslow Taylor, "Scientific management means

knowing exactly what you want men to do and seeing that they do it in the

best and the cheapest way."

Time Study

time and motion study: an analysis of a specific job in an effort to find the

most efficient method in terms of time and effort

Time study is a direct and continuous observation of a task, using a

timekeeping device (e.g., decimal minute stopwatch, computer-assistedelectronic stopwatch, and videotape camera) to record the time taken to

accomplish a taskand it is often used when

there are repetitive work cycles of short to long duration,

wide variety of dissimilar work is performed,

Incentive plans

Incentive plans are part of an employee's compensation or pay.

The incentive plan gives an employee the opportunity to

increase his annual pay based upon either company

performance or individual performance. Incentive plans are a

way for companies to keep employees motivated to perform tothe best of their abilities, thus increasing company profit.

Henry Gantt

18611919

Contribution is scheduling Chart.


16/22

Scheduling Chart

Frequently used in project management, a Gantt chart provides a graphical

illustration of a schedule that helps to plan, coordinate, and track specific

tasks in a project.

Such as MS Projects and Excel

Blackett

1897 1974

Contribution is Operation Research (OR)

George Dantzig

1914

2005 American Mathematical scientist who made important contributions

to Linear programming .


19/22

It is a mathematical technique to find the best outcome with limited

resources i.e. to achieve maximum profit with minimum cost. This method

is possible only with the linear relationships. This technique is also called

as linear optimization.

Linear programming is often used in business to find maximum profit or

minimum cost
