2. Definition
Material management is the process of planning,
storing and providing appropriate material of the
right quality, right quantity at the right place in the
right time.
According to IFPMM
“It is total concept which has a definite organization, to plan
and control all types of materials, its supply and its flow from
the raw stage to the finished stage so as to deliver the product
to the customer as per his requirement in time”
The material cost constitute a major portion of the
total manufacturing cost.
Around 60 to 65% of the total cost of
manufacturing is that of material
3. Functions of Material Management
Material Planning
Purchasing
Procurement
Stores management
Inventory control
Value analysis of costly material
Smooth flow of material
4. Inventory
It is detailed list of movable items which are
required for manufacturing products and
maintaining the equipment and machines in
good working order.
Raw Material
(Direct material)
Indirect
Material
Finished Goods
Work-in-progress
Good
Inventory
5. Objectives of Inventory Management
Operational Objectives
To ensure continuous supply of materials, spares &
finished goods so that production should not suffer.
To avoid both over stocking & under stocking
To minimize losses resulting from deterioration,
obsolescence or price decline.
Financial Objectives
To maintain investment in inventories at the
optimum level
To keep material cost under control so as to reduce
cost.
6. Objectives of Inventory Management
Property Protection Objectives
To safeguard inventory against theft, wastage,
damage or unauthorized use.
To ensure material actually lying in the stores are
shown in stock ledger & value is correctly stated.
7. Inventory Analysis
It is not practicable to have high degree of
control on all items.
So, it is desirable to group the items and subject
each group of items to different controls based
on their importance.

8. ABC Analysis
It is based on the principle of “Vital Few-Trivial
more”.
The goal of this is to categorize items which would
be prioritized, managed or controlled in different
ways.
In this analysis inventory is classified into 3
categories
Item ‘A’: Complex & expensive parts that require
careful management & control. This are high value
& low volume kind of item. Despite low volume, their
annual consumption cost is high as these are vital
few.
9. ABC Analysis
Item ‘B’: Moderately Complex & expensive parts
that require moderate level of management &
control. This are moderate value & moderate
volume kind of item.
Item ‘C’: Low Complex & low expensive parts that
require low level of management & control. This are
low value & high volume kind of item like Trivial
More.
Class of Item % of Total Consumption
Cost
% of Total No. of
Items
A 70 to 75 10 to 20
B 15 to 25 20 to 30
C 5 to 10 50 to 70
10. Steps in ABC Analysis
List all the items used in industry
Obtain the cost data & consumption volume for
each part
Calculate Consumption cost: multiply item cost
by quantity
Arrange all items in descending order of the
consumption cost.
Calculate cumulative consumption cost
Calculate cumulative consumption cost of each
item in percentage.
Plot a graph of cumulative percentage on Y –axis
& cumulative percentage on X-axis.
11. EOQ (Economic Order Quantity)
It is “Optimal quantity of order that minimizes total
variable cost required to order & hold inventory.
Two questions has to answered:
How much should we order?
How often should we order?
Significance of EOQ:
Used to review inventory system so as to monitored
at all time
To calculate reorder point and optimal quantity so
as to get the material in JIT.
12. Contd…
Assumption:
Ordering cost is constant
Rate of demand/consumption is constant
Lead time is fixed
Purchase price does not change
Total quantity ordered is in one batch.
13. Cost incurred for EOQ
Procurement Cost
Each event of ordering has a certain cost like
paperwork needs to filled out, peoples need to be
contacted, told how much to order.
When the inventory comes in, it has to be inspected
and then stocked & invoices need to be prepared.
Procurement cost are inversely proportional to EOQ.
It includes
Receiving Quotation
Processing quotation & issuing PO
Follow up & expediting PO
Transportation
Receiving, inspecting & stocking material
Processing Vendor invoice
14. Cost incurred for EOQ
Carrying (Holding) Cost
These cost increase as you hold more & more
inventory
We need to take loans to pay for them & interest has
to be paid.
It may also obsolete or deteriorate with time.
The more space you need to occupy
Directly proportional to EOQ
In includes
Interest on capital investment
Storage cost
Record keeping
Deterioration & obsolescence
Insurance, theft, property tax etc
15. Analytical Method to calculate EOQ
A- Annual Consumption
P- Procurement Cost per Order
C- Cost of item
I- Cost of carrying inventory in percentage per
period including interest, insurance, storage,
obsolescence etc..
C*I- Annual inventory Carrying cost per item
Q- EOQ
PC=P*A/Q
CC=Q/2*C*I
16. Purchase Procedure
Purchasing is the procedure of acquiring goods,
materials, components, equipment's, tools etc.
Objectives of Purchasing
To procure Right Material
To ensure quality of material
To procure material in right Quantity
To procure material @ Reasonable Price
To develop Reliable Source & maintain
relationship
To develop alternative Sources
To Avoid duplication, Waste & Obsolescence
Integration with other dept.
21. Contd…
Send enquiry to the vendors :-
The buyer releases the enquiry to the vendors.
3 vendors.
Capability of making items as per the quality
required.
Essential to fill up the quality requirements of
the item.
22. Contd…
Get Quotations from Vendors :-
• Buyer gets Quotations from different vendors.
• Maximum 3 are selected.
• He tabulates the quotations and finds the
lowest quoting vendor suitable according to
the buyers estimated cost.
23. Contd…
Study and compare the quotations with our
estimated costs :-
The buyer selects 3 vendors.
From these 3 vendors the lowest quoting
member is chosen.
24. Contd…
Negotiating the quoting to fix the price :-
The buyer negotiates with the vendor to agree
upon a certain amount.
Both the buyer and the vendor conclude with
a fixed negotiated price.
Hence the order is placed to the right vendor.
25. Contd…
Follow-up with the vendor :-
Important function in the life of a buyer.
Highly under valued and seen as unpleasant.
Buyer has to have good skills to follow up.
Rarely vendor supplies materials as he promises
and as what is discussed and agreed amongst
two parties.
26. Contd…
Get and inspect the material :-
The buyer get the material from the vendor.
Buyer imports the materials from the vendor
and inspects it accordingly.
Inspection leads to “make sure no damage
is occurred while transporting and it must be
as per the booking of the buyer.”
Inspection is mainly done by the purchase
department professionals.
27. Contd…
Stores credit the material :-
After inspecting done by the buyer, the buyer
stores the goods in the warehouse.
Payments are made on cash or credit basis.
