The changes in production very often occur along with the development of technology used. An industrial engineer must be sensitive to changes occurring in the process sometimes unnecessary Originally process and work are deems as Necessary. Activities that should be removed occasionally still maintained by reason of changes in procedures requiring a change in the side of labor, machinery and process flow, changes in procedures also require changes in the workforce. They must be trained to follow the new working procedures. This change will be slow because it is still pictured with the old procedure. So the work habits of the old still remains taken although there has been new work procedures. So the activities that should not have to do is just done, resulting in a waste of time.
