engineering management

Engineering management is a specialized form of management concerned with the application in engineering, as a result of the unique personalities and technical nature of engineering. Engineering Management programs typically include instruction in accounting, economics, finance, human resources management, industrial psychology, management information systems, mathematical modeling and optimization, quality control, operations research, safety and health issues, and environmental management.^[1][2] Whereas the term project management refers to human resourcing, engineering management refers to the functional management of technical professionals. Example areas of engineering are product development, manufacturing, construction, design engineering, industrial engineering, technology, production, or any other field that employs personnel who perform an engineering function.

example;span of  control

Span of control is a term originating in military organization theory, but now used more commonly in business management, particularly human resource management.Span of control refers to the number of subordinates a supervisor has. In the hierarchical business organization of the past it was not uncommon to see average spans of 1 to 4 or even less.

Factors affecting span of control

These are the factors affecting span of control:

1. Geographical Location, if the branches of a business are widely dispersed, then the manager will find it difficult to supervise each of them, as such the span on control will be smaller.
2. Capability of workers, if workers are highly capable, and do not require much supervision and can be left on their own, eg: Theory Y type of people, need not be supervised much as they are motivated and take initiative to work,as such the span of control will be wider.
3. Similarity of task, if the task that the subordinates are performing are similar, then the span of control can be wider, as the manager can supervise them all at the same time. However, of course the capability of the supervisor has to also be taken into consideration.
