what a manager is, and how the role of manager has changed?

Answer 1

Hey, am I doing your homework for you?

A manager is someone who manages people, processess, or systems.

It's changed over the past decades with the introduction of technology. Management has shifted from a people based role to a system management role. It used to be more common for managers to be in charge of a group of people getting a job done. It;s common now for managers to be responsible for keeping the computers working to get the job done.

For example, jobs like "office manager" used to be responsible for keeping the secretarial pool of people on task doing their typing and such. Now, an office manager is usually responsible for the technology in the office (computers, copiers, printers, ordering supplies, programming phones, etc.) rather than secretarial duties.

"Management" (from Old French ménagement "the art of conducting, directing", from Latin manu agere "to lead by the hand") characterises the process of leading and directing all or part of an organisation, often a business, through the deployment and manipulation of resources (human, financial, material, intellectual or intangible). Early twentieth-century management writer Mary Parker Follett defined management as "the art of getting things done through people."

Some argue modern management as a discipline began as an off-shoot of economics in the 19th century. Classical economists such as Adam Smith and John Stuart Mill provided a theoretical background to resource allocation, production, and pricing issues.

By about 1900 we find managers trying to place their theories on a what they thought was a thoroughly scientific basis (see scientism for the limits of this claim). Examples include Henry Towne's Science of management in the 1890s, Frederick Winslow Taylor's Scientific management (1911), Frank and Lillian Gilbreth's Applied motion study (1917), and Henry L. Gantt's charts (1910s). J. Duncan wrote the first college management textbook in 1911. In 1912 Yoichi Ueno introduced Taylorism to Japan and was first management consultant to create the "Japanese-management style". His son Ichiro Ueno pioneered Japanese quality assurance.
