‘Types of Inventory’ is the focus for this session. While dealing with components of logistics,
we have already seen the basics of inventory.
We shall see now the types of inventory.
Traditionally, it is said that there are four types of Inventory and
they are Raw materials, Work in
progress, Finished goods and MRO goods.
If you are a manufacturer, all things you need to manufacture a
product are basically raw materials for you.
You convert those raw materials into the product of your company. Supposing you partially assemble some part of
a product, say a wheel for some two or three wheelers, this subassembly is your
raw material. Your subassembly becomes a part of a finished product. Your subassembly is the component of the
finished product. Generally a part that
is used in making another product or even a part is known as component and the
part that is taken into a finished product is called its parent.
The sole aim of the inventory is to keep the product available to meet
the demand from a customer. A
dissatisfied customer may prove an ‘exit’ customer for the company and the
company loses revenue to the extent it faces exit customers.
Material Requirements Planning system, Manufacturing Resource
Planning and Product Structure Tree are
other popular and necessary aspects being discussed under inventory
generally. All these concepts underscore
one fact as earlier said: Things must be kept or managed in such a way that the
customer’s need is met in the right time, in the right way and in the right
place. At the same time, in order to make things available to the customer in
time, overstocking materials, as much as under stocking, is not a right
business strategy. Money spent in excess
to the need is money wasted. Right business does not waste money at all; it

in our next session.
