Job Description - BSI definition (32207) - a written outline of the main tasks of a job.
Essentially a broad statement of the purpose, scope, accountabilities and tasks which constitute a particular job.
An organisation structure is usually specified by means of an organisation chart (which shows relationships) and a set of job descriptions which indicate the content of the jobs themselves. Job descriptions specify the nature of managerial responsibilities in outline. In addition to their many obvious uses in clarifying responsibilities and boundaries they are an essential basis for the job specification (q.v.), job evaluation and for merit rating (q.v.) of the personal appraisal (q.v.).
