Staffing is the process through which an organization insures that it always has the proper number of employees with appropriate skills in the right jobs at the right time to achieve the organization’s objectives. Staffing involves job analysis, human resource planning, recruitment and selection. All areas of staffing would be haphazard if the recruiter did not know the qualifications needed to perform the various jobs. Lacking up-to-date job descriptions and specifications, a firm would have to recruit and select employees for jobs without having clear guidelines; this practice could have disastrous consequences. Job analysis is conducted after the job has been designed, the worker has been trained and the job is being performed. Human resource planning involves matching the internal and external supply of people with job openings anticipated in the organization over a specified period of time. Because conditions in the external and internal environments can change quickly, the human resource planning process must be continuous. Changing conditions could affect the entire organization, thereby requiring extensive modification of forecasts.
