JOB ANALYSIS METHODS


Job analysis information can be gathered in a variety of ways. One consideration is who is to conduct the job analysis. Most frequently, a member of the HR staff coordinates this effort. Depending on which of the methods discussed next is used, others who often participate are managers, supervisors, and employees doing the jobs. For more complex analyses, industrial engineers may conduct time and motion studies.
Another consideration is the method to be used. Common methods are observations, interviews, questionnaires, and specialized methods of analysis. Combinations of these approaches frequently are used, depending on the situation and the organization. Each of these methods is discussed in some detail next.
Observation
When the observation method is used, a manager, job analyst, or industrial engineer observes the individual performing the job and takes notes to describe the tasks and duties performed. Observation may be continuous or based on intermittent sampling.
Use of the observation method is limited because many jobs do not have complete and easily observed job duties or complete job cycles. Thus, observation may be more useful for repetitive jobs and in conjunction with other methods.
Managers or job analysts using other methods may watch parts of a job being performed to gain a general familiarity with the job and the conditions under which it is performed. Multiple observations on several occasions also will help them use some of the other job analysis methods more effectively.
WORK SAMPLING
As a type of observation, work sampling does not require attention to each detailed action throughout an entire work cycle. Instead, a manager can determine the content and pace of a typical workday through statistical sampling of certain actions rather than through continuous observation and timing of all actions. Work sampling is particularly useful for routine and repetitive jobs.
EMPLOYEE DIARY/LOG
Another method requires that employees “observe” their own performances by keeping a diary/log of their job duties, noting how frequently they are performed and the time required for each duty. Although this approach sometimes generates useful information, it may be burdensome for employees
to compile an accurate log. Also, employees sometimes perceive this approach
as creating needless documentation that detracts from the performance of their work.
Interviewing
The interview method of gathering information requires that a manager or HR
specialist visit each job site and talk with the employees performing each job. A standardized interview form is used most often to record the information. Frequently, both the employee and the employee’s supervisor must be interviewed to obtain a complete understanding of the job. In some situations, such as teamdirected jobs, group interviews also can be used, typically involving experienced job incumbents and/or supervisors. It usually requires the presence of a representative from the HR department as a mediator. For certain difficult-to-define jobs, group interviews are probably most appropriate.
The interview method can be quite time consuming, especially if the interviewer talks with two or three employees doing each job. Professional and managerial jobs often are more complicated to analyze and usually require longer interviews. For these reasons, combining the interview with one of the other methods is suggested.
Questionnaires
The questionnaire is a widely used method of gathering data on jobs. A survey instrument is developed and given to employees and managers to complete.  The major advantage of the questionnaire method is that information on a large number of jobs can be collected inexpensively in a relatively short period of time. However, the questionnaire method assumes that employees can accurately analyze and communicate information about their jobs. Employees may vary in their perceptions of the jobs, and even in their literacy. For these reasons, the questionnaire method is usually combined with interviews and observations to clarify and verify the questionnaire information.
One type of questionnaire sometimes used is a checklist. Differing from the open-ended questionnaire, the checklist offers a simplified way for employees to give information. An obvious difficulty with the checklist is constructing it,
which can be a complicated and detailed process.
