When involved in developing job analysis, job incumbents tend to see their jobs as requiring greater skill and knowledge than do line managers or outside job analysts.

Job incumbents are more likely to have a firsthand understanding of the skills and knowledge required for their job, as they have direct experience performing the tasks and responsibilities involved. Therefore, they may have a biased perspective that overestimates the level of complexity and expertise required for their role. In contrast, line managers or outside job analysts may have a more objective and comprehensive view of the job requirements.
