Applied Motion Study
A Collection Method to industrial Preparedness

38 APPLIED MOTION STUDY Improvements in standards are wanted and adopted whenever and wherever they are found. There is abso- lutely nothing in standardisation to preclude innovation. But to protect standards from changes which are not in the direction of improvement, certain safeguards are erected. These safeguards protect standards from change for the sake of change. All that is demanded under modern scientific management is that a proposed change in a standard must be scrutinised as carefully as the standard was scrutinised prior to its adoption, and further that this work be done by experts as com- petent to do it as were those who originally framed the standard. Standards adopted and protected in this way produce the best that is known at any one time. Stand- ardisation practised in this way is a constant invitation to experimentation and improvement. This experimentation and improvement are done by time and motion study before the stand- ards are made. Thus the resulting standard is in so far perfected that only the invention of a new device will make a change in the standard neces- sary. The fact that such devices are often the re- sult of the motion study also assists in making the standards that are incorporated from the completed study more permanent. As was well shown by Mr. John G. Aldrich, in a paper read before the American Society of
