By assigning relative value to every KSA, employers underline the most important aspects of a job. Others will identify specific KSAs as mandatory or desirable. The job candidate usually wants to concentrate the most on reacting to more severe KSAs or obligatory KSAs, but it is important to remember that everybody in the list has to be addressed. One important note is that all KSAs must relate to the specific work. An employer cannot ask for anything in KSA that is not in the job description.
