In lean manufacturing the wastes are defined as anything which does not add value to the end
product. If customer sees the value with the end product, it is very much fair to define a waste in
this way. Customers do not mind how much it costs you to repair damage, cost for your huge stocks
and stores or other over heads. There are wastes that can be avoided, but some are unavoidable to
many reasons. When identifying the wastes and categorize them in to avoidable and unavoidable,
you have to think about removing the wastes from the system. However, lean manufacturing always
talks about removing, not minimizing. The wastes are everywhere in many different forms. Every
organization wastes majority of their resources. Therefore it is worthier to have a closer look at
these wastes. These wastes are categorized in to eight categories.
