Human skills involve the ability to work well with other people, both individually and in a group. The importance of human skills remains consistent, regardless of level within the organization. Finally, conceptual skills include the ability to think and conceptualize about broad organizational issues and to see how the various organizational subunits interact and how the organization fits into its broader environment. These types of skills are most important at the upper levels of management. The job of manager changes only in degrees as one moves up in the organization.
All managers plan, organize, lead, and control.
Yet higher level managers tend to plan more while lower level managers tend to lead more. Both the mayor and corporate president oversee an organization. Both plan, organize, lead, and control. Both seek effectiveness through efficiency. Is is more difficult, therefore, to judge the effectiveness of the mayor than the corporate president.
