The job description must contain a general list of the responsibilities and tasks associated with the role, along with the expected time to be dedicated to each task. This should be represented either through descriptive attributes: primary task – filing, secondary – data entry or through percentages (40% filing, 20% data entry)
Description of the duties should be no more than one or two sentences in lengths and should be outcome-based, containing an objective, action and purpose e.g. compiles monthly reports to allow departmental budget monitoring
The list of duties will vary in length, but as a rule, should be as short as possible, otherwise the job description turns into a manual rather than a job description.
Roles in smaller companies may have more tasks associated with them, due to the ‘all-round” nature of the task, but you should still aim to keep the list to around 15-20 as a maximum.
