What are the methods of job analysis?

The project of job analysis by questionnaire method can be in the form of questionnaire, and the incumbent and the boss of the incumbent can be asked to answer. These questions can be designed as open or closed, and appear in the form of multiple-choice questions or true-false questions. 1. Advantages (1) Getting job analysis information is faster, more efficient and more time-saving. (2) If the questionnaire is well designed, more information can be collected. (3) Support other methods of collecting work information, such as interview, observation and workday realism, which are mutually supportive. 2. Disadvantages (1) It takes a high level and time to design the questionnaire. (2) Simply using questionnaires may not be taken seriously by employees. (3) Employees who are not very skilled in language expression may provide wrong information. Interview method Interview method 1 * * * mainly has three forms: the first is to interview each employee individually; The second is to conduct a collective interview for employees engaged in this position; The third is to interview the superior supervisor of this position, who will introduce or answer the relevant information of this position. These three methods can be used in combination, such as interviewing individual employees first, then interviewing collectively or interviewing with superiors. Interview is also a widely used job analysis method. The advantage of this method is that you can find problems that other methods can't, because you can communicate face to face. 1. Advantages (1) Let employees understand the problem and give clear answers. If the answer is not clear, the job analyst can ask him face to face. (2) Take the opportunity to communicate with employees and improve the relationship between human resources department and employees. 2. Disadvantages (1) Some employees will intentionally or unintentionally exaggerate the importance of their posts and may write some information or job responsibilities that do not belong to them. (2) The interview method takes a long time and has a large workload, so it can be combined with the questionnaire method in the actual implementation process. It is suggested that the following matters must be kept in mind when using the interview method: a, pay attention to close cooperation with the direct supervisor being interviewed; B establish a harmonious relationship with the post holder: the purpose of the interview should be clearly introduced, the language used should be easy to understand and maintain a harmonious atmosphere. C. Have a well-designed interview outline to support your question; D, the interviewee needs to make some lists according to the importance of the work, and there should be no omissions; E, after the interview, but also check and check the interview materials. This method is mainly to check with the superior supervisor, or compare the information of the employees in the same position. Observation helps post analysts to understand the production process and reduce misunderstandings, but it takes up time, which is suitable for assembly line workers and positions with short cycle and strong regularity, but not for mental workers, firefighters and middle and senior managers. The realistic method of working day is to write a work log. Its advantage is that it can provide a complete working picture, and its disadvantage is similar to observation method, which takes a long time and is suitable for middle and low-level personnel and workers. Generally speaking, observation and workday realism are not used alone, but together with questionnaires and interviews.
