To be able to acquire a system, improve the analysis of information, it is best for this work the actual investigation. Investigation of many species, we introduced the following several major ways. 1, interview with the interview for the job duties of the officers to discuss the characteristics and requirements, obtain relevant information survey research methods. Analysis of the work, we can inspect and sort out the relevant duties of the existing information. In general understanding of the duties on the basis of such work visit to the office staff, to discuss the characteristics and requirements. , We may also interview the managers and engaged in the corresponding training of teachers. As the visit of those who are most familiar with this work, therefore, The interviews can seriously detailed analysis of the data. Interview to the attention of that deviation. Sometimes interviews will be intentionally or unintentionally distort their jobs, for example, put an easy task to put it difficult or hard to work a little more easily. This depends on the same level and in a number of interviews that the information collected to be compared correction. 2, the questionnaire questionnaire is to enable staff to answer in writing duties, the investigation methods. Usually, the contents of the questionnaire analysis by the work of staffing problems or statements These questions and statements involve actual behavior and psychological qualities, asked respondents to these acts and the psychological quality of their work and the importance of frequency (regular) on the way to answer. Generally, the answer should have three levels : (a) the quality of the various special needs : must contain; Must possess; not possess. (2) any special quality in a work of the application number : often used; Sometimes the application; never applied to. (3) If the quality of the various special training can be received effect : be much progress; Shaoke progress; May not be able to progress. Questionnaire can be divided into office directional orientation and the two officers. Directional questionnaires duties emphasize their own conditions and results; Directional officers questionnaire focuses on understanding the staff for their work behavior. The questionnaire is the greatest comparative advantages of standardization and quantification, which is suitable for using computers to the results for statistical analysis. But its design fee for comparison, the interview did not like to be face-to-face exchange of information, therefore, it is not easy to understand the subject of the investigation attitude and motivation deeper level information. Questionnaires have two shortcomings : First, be difficult to arouse interest in the subject of the investigation; Second, unless a very long questionnaire. Otherwise, it will not be sufficiently detailed information. 3, check this law is to enable staff to the list of tasks to identify with their work-related projects, in order to determine the characteristics of a particular work. 4, observation questionnaire, Interview and work methods to check analysis methods can be effective collection of information office, But they have certain weaknesses. There is a larger issue that experienced staff is not always aware of their completion of the forms. Many acts work has become a habit, and started to work unaware of the details of procedures. Therefore, the researchers advocate the use of observation of staff in the process of observation, recording the characteristics of the area; Meanwhile, work by the understanding of the tools used equipment; understand the procedure, working environment and physical exertion. Observation, can be written down; Can be prepared in advance with good observation list, while observation, the side check. In the use of observation list, prior to this work I do. Thus, the development of the observation list is rather practical. Observation before interviews will be conducive to observe the work. On one hand, it is conducive to grasp the broad framework for observation. The other hand it enables the two sides have mutual understanding and establish a cooperative relationship. Thus, the subsequent observation to a more natural, smooth. 5, technical meetings this law is to convene managers and technical staff meetings, discuss features and requirements. As the management and technical staff to work more understanding, In particular understanding of the work of the technical attributes and characteristics. Therefore, their views on access to information on job analysis is very useful. 6, the diary method is the method used to allow staff to work diary recorded daily work activities. Working as impurities information. This approach requires staff for a period of time to do their own work for all records of the system's activities. If this record can remember very detailed, so often suggest some other methods can not be observed or not the details. 7, the work involved in this work is by analysts to participate in work activities, Experience of the whole process, from getting a job analysis data. To work on a profound understanding, the best way is to personally practice. Through field visits, detailed and in-depth experience understand and analyze the work of some psychological factors and the necessary quality of various psychological and behavioral model. Therefore, analysis of the work was the quality of information is concerned, this method over the previous several ways to good effect. 8, critical incident key events Law Act is to ask managers and staff recalled, report on their work performance, it is rather the work of the key features and events, thus obtaining work analyzing information. In general, the working methods of analysis can be divided into positions targeted methods and acts directed method. The former relative to the static job description and analysis of the characteristics of the collection of the "job description" a kind of material; The latter concentrated in the "requirements" Adaptation of work, is a relatively dynamic analysis. Critical incident is a common method of directional method. This approach requires managers, familiar with the staff and other personnel at work recording acts of "critical incidents" -- so that success or failure The behavioral characteristics or events. Massive collection of the key events, they can analyze and summarize the key job characteristics and behavior requirements. Critical incident can be the law office of static information, but also to understand the dynamic characteristics of duties.
