Job specialization can be defined as a strategic process which typically involves the ability of employees working in an organization to develop specific skills, knowledge, great expertise or professionalism and experience to perform their duties, tasks or job functions effectively and efficiently.
In order to gain the requisite skills, expertise and knowledge for job specialization, it is very important for the employees to have undergone an extensive training and a good number of years in work experience.
The primary purpose of job specialization is to increase efficiency and productivity because the employees are able to specialize in the use of specific tools (equipments) to accomplish their tasks, as well as limit the level of error or mistakes in the production process.
In Business management, method analysis can be defined as the study of the detailed process for the performance of a job i.e how a job is done. Thus, method analysis gives a detailed report on the tasks involved in the performance of a job and how they are to be done.
Basically, methods analysis is particularly valuable when it is used on jobs that:
1. Are high in labor content.
2. Are done frequently.
3. Are unsafe, tiring, unpleasant, and/or noisy.
