Abstract: In any production system, wastes is something which is not adding value to the system and these are basically the operations named as non-value added operations or activities. However, it has been observed that the most of the time, the communal always considers wastes as the typical scraps in any lean production system. Hence, the authors of this research study have conducted a literature review which explains about the typical wastes acting in any lean production systems which are seven in number and named as over production, over waiting, over transportation, over motion, over inventory, defects and over processing. Moreover, it has been observed that the underutilization of employees is also considered as the one of the wastes which was previously not in the list seven wastes and considered as the eight leading wastes. The input of this literature study is the explanation of eight wastes affecting the system which will be helpful for communal to understand and explain wastes affecting systems.
