Assess the job at hand! A deep analysis of the job’s tasks is for starters. –
Interview the team and observe how the tasks are being performed. Have the current team and management review what you’ve gathered in the analysis to further tweak. Now, at this point, you should be able to start listing the essential functions of the job. Lay it out in draft to ensure you have at minimum, the name of role, salary range (or grade) and classification if required, area of performance, objective of the role, essential functions, skills required, qualifications, to include experience levels, and education levels required. Make sure to get upper management’s approval before publishing.
