Which term refers to a collection of tasks and responsibilities performed by a single individual?

The term that best describes a collection of tasks and responsibilities performed by a single individual is "Position." A position refers to the specific role that an individual occupies within an organization, encompassing the duties they are tasked with, the responsibilities they hold, and their place within the organizational structure. Each position is unique to the individual who occupies it and is defined by the combination of tasks they perform and the functions they fulfill.

In contrast, a job description outlines the duties and responsibilities associated with a particular job title but does not specify who completes those tasks. Job analysis involves the systematic study of jobs to determine their components, requirements, and contributions to the organization, serving as a foundational step in developing job descriptions and specifications. Job specification, on the other hand, details the qualifications, skills, and experience necessary for a position, focusing primarily on the attributes needed from candidates rather than the tasks performed by the individual in that role.

Thus, "Position" accurately captures the idea of a complete set of tasks and responsibilities linked to a single individual within the workplace.
