There is a concept called "lean thinking" which was recently applied to a corporation which was considered to be one of best in quality management. This concept of "lean thinking" refers to stepping beyond the paradigm of "production" and focusing on the relations of the management to worker, and worker to customer to establish a strong relationship among the three.
This is how management ends up being more of a human activity: When a vision and mission are established in an organization, it is the supervisory staff which also settles how the approaches will be put in place to accomplish the organizational goals.
It is the people, also, who put them in place, and it is the people who decide how much of "themselves" they are going to put in the process to ensure quality. In the case of the company that I mentioned previously, they applied all this to their "lean thinking" method as a way to motivate the employees to provide the best quality service possible.
It is indeed the people who make and direct the management, and it is the human factor which ensures success. More on the "lean thinking" paradigm on the link provided.
Management is primarily a human activity. Any activity which can be performed primarily by machines is an operational activity. For example, the basic task of producing steel from iron ore in a steel mill is an operational task. But when we come to the question of how to produce the steel of better quality, at lower cost and and in adequate quantities to meet customer requirements, we need to go beyond the technology of steel making operations.
The technology of steel making requires that the total steel making operation be divided in hundreds of sub-operations to be performed by different people. The function of management is to ensure that people performing these hundreds of interrelated sub-operation in a properly co-ordinated way. This involves management functions such as planning, organizing, motivating and control. All these management functions deal primarily with people. Functions like organization and motivating are almost exclusively concerned with people and their work.
Thus we see that management is more of human activity.
