Explanation:

Job Analysis is a primary tool to collect job-related data. The process results in collecting and recording two data sets including job description and job specification. Any job vacancy can not be filled until and unless HR manager has these two sets of data. It is necessary to define them accurately in order to fit the right person at the right place and at the right time. This helps both employer and employee understand what exactly needs to be delivered and how.

Both job description and job specification are essential parts of job analysis information. Writing them clearly and accurately helps organization and workers cope with many challenges while onboard.
