According to Business Dictionary:
A group of homogeneous tasks related by similarity of functions. When performed by an employee in an exchange for pay, a job consists of duties, responsibilities, and tasks (performance elements) that are (1) defined and specific, and (2) can be accomplished, quantified, measured, and rated. From a wider perspective, a job is synonymous with a role and includes the physical and social aspects of a work environment. Often, individuals identify themselves with their job or role (foreman, supervisor, engineer, etc.) and derive motivation from its uniqueness or usefulness.
