(a) Operation: It involves a change in the location or condition of a product.
(b) Inspection: It is an act of checking for correctness of the quantity or quality of the items.
(c) Transport: It indicates the movement of an item from one location to another.
(d) Delay: It occurs when something stops the process and a product waits for the next event.
(e) Storage: It represents a stage when a finished good or raw material awaits an action or when an item has been retained for quite some time for reference purposes.
