Even before the bonus is paid, the worker will not vary for any slight reasons, if he positively knows at the time that he must account for so doing, and that he will be considered to have "stacked his judgment" against that of the manager. Being called to account for deviations gives the man a feeling of responsibility for his act, and also makes him feel his close relationship with the managers. NO SET TIME FOR USING SYSTEMS.--There is, under this type of management, no set time for the study of the systems. SYSTEMS INELASTIC.--Being written, these systems have all the disadvantages of anything that is written. That is to say, they require considerable adaptability on the part of the man who is using them. He must consider his own mind, and the amount of time which he must put on studying; he must consider his own work, and adapting that method to his work while still obeying instructions. In the case of the system being in great detail, he can usually find a fairly detailed description of what he is going to do, and can use that. In the case of the system being not so complete, if his work varies, he must show intelligence in varying the system, and this intelligence often demands a knowledge which he has not, and knows not where to obtain. WASTE OF TIME FROM UNSTANDARDIZED SYSTEMS.--The time necessitated by the worker's laying out details of his method is taken from the total time of his working day, hence in so far cuts down his total product. Moreover, if no record is kept of the details of his planning the next worker on the same kind of work must repeat the investigation. LATER TRANSITIONAL MANAGEMENT EMPHASIZES USE OF STANDARDS.--Later Transitional Management eliminates this waste of time by standardizing methods composed of standardized timed units, thus both rendering standards elastic, and furnishing details. TEACHING MOST IMPORTANT UNDER SCIENTIFIC MANAGEMENT.--Teaching is a most important element under Scientific Management not only because it increases industrial efficiency, but also because it fosters industrial peace.[2]
