Objectives are the aims of a course of action. The common usage was originally military, referring to operational aims. That usage translated easily into the corporate sphere, and is now a common term for business goals, career goals, and the aims of other forms of planned action.
Objectives can be categorized:
Strategic/primary objectives- The major goals.
Secondary objectives- Related but less important goals.
Tactical objectives- Aims for achievement in local operational activities.
Staged objectives- A progressive series of goals and achievements.
