Explanation:

According to the "General Model of Job Design" job performance is influenced by perceived job content. Perceived job content has to do with how significant an employee views a job and the related skill they need for the job. An employee will do a job properly if he feels that the job is important for his/her career advancement and if it is important to achieving the organizations long-term or short-term goal, his performance of that job/task is based on how significant he views the task. Another consideration is the skill set, an employee will perform a job better if he/she has the necessary skill required for that job.
