Internal consistency is very important when developing an overall bank of organizational job descriptions. The employer may want to select specific formats, fonts, logos, and other elements to streamline and standardize the appearance of the documents. Consistent language such as preferred action words and frequently used terms can help create cohesiveness throughout. Internal consistency may also help “ensure equitable comparisons of content across jobs” in justifying employee salary decisions (Milkovich and Newman, 1990).
Here’s a sample of job descriptions, ranked from good to bad. Looking through them alongside their scores makes it obvious why some are better than others, and is a good exercise to teach yourself to get better at writing them.
