Consider a plant producing widgets and dyes. The raw materials are purchased in bulk and delivered from the supplier to be placed in a warehouse until requested by the production departments. The warehouse has 24-hour security guards and one full-time maintenance person. The materials are then delivered to the departments three miles away by truck, where they are used in the production of widgets and dyes. During production the pieces are inspected twice. After production the finished product is stored in another warehouse until it is shipped to customers.
Identify the value-added and non-value-added activities.
