The difference between post-realism and homework timing is ().

The main differences between post-realism and homework timing are as follows: ① The research scope of the two is different. Post-realism is based on the overall observation of the whole working day; And job timing is only a part of the working day, that is, the activities of a process or job. ② The fineness of observation is different between them. Post-realism not only studies the consumption of working hours, but also studies the content and structural proportion of various activities, but focuses more on the latter and is more "rough"; However, work timing only studies the content of work activities and the consumption of working time in the process, which is "fine". ③ Their specific functions are different. The main purpose of post realism is to master the subjective and objective data and materials related to post work activities, and provide basis for post analysis and post design; The main purpose of job timing is to improve the content of job activities, rationalize job methods, save working hours and determine advanced labor quotas.
