3. Introduction
Inventory can be referred to as sum of the value of
Raw materials (RM),
Fuels and lubricants,
Equipments & Spare parts,
Maintenance, repair & operating supplies (MRO)
WIP: work in progress (Semi- finished products)
Finished goods stock (FG)

5. Inventory Basics
Inventory is created when the receipt of materials, parts, or
finished goods exceeds their disbursement.
Inventory is depleted when their disbursement exceeds their
receipt.
An inventory manager’s job is to balance the advantages and
disadvantages of both low and high inventories.
6. Types of Inventory
Raw materials Inventory- This consists of basic materials that have not
yet been committed to production in a manufacturing firm.
Stores and Spares- Examples of stores and spares items are bolts, nuts,
clamps, screws etc.
Work-in-Process Inventory- materials that have been committed to the
production process but have not been completed.
Finished Goods Inventory- These are completed products awaiting sale.
7. Purpose of holding Inventory
Avoid Lost of Sales
Gain Quantity Discounts
Improve customer service
Transportation savings
Unplanned shocks (labor strikes, natural disasters, etc.)
8. Characteristics / Importance
Inventories serves as cushions to absorb shocks.
Inventory for any organization is necessary evil.
Inventories are result of many interrelated decisions and
policies of an organization.
Inventory provides production economy.
10. Inventory management
Inventory management is the planning and controlling of inventories in
order to meet the competitive priorities of the organization.
Effective inventory management is essential for realizing the full
potential of any value chain.
Inventory management requires information about expected demands,
amounts on hand and amounts on order for every item stocked at all
locations.
The appropriate timing and size of the reorder quantities must also be
determined.
11. Effective Inventory management
The goal of effective inventory management is to minimize the
total costs - direct and indirect - that are associated with
holding inventories.
Effective Inventory Management enables an
organization to meet or exceed customers'
expectations of product availability while
maximizing net profits or minimizing costs.
12. Benefits of Inventory Management
Reduces inventory & purchasing cost
Gain visibility into inventory process
Improve customer service
Reduce time to market
13. Factors affecting Inventory
The number of factors can be divided in the following categories.
Characteristic of Manufacturing System- The nature of production
process, production planning, plant layout have an effect on inventory
policy.
Amount of Protection against shortages- Due to fluctuation in
demand of the product
Organizational factors- Amount of capital available for stock , Storage
and warehousing policies.
Other factors-Strike situations,Wars, or some other natural calamities
like floods, earthquakes, etc.
14. Inventory Control
Inventory control is a planned systematic method to determine
The inventory to be indented,
Its quantity to be indented and stocked,
To keep the purchasing and storing costs to the minimum
possible.
15. OBJECTIVES OF INVENTORY CONTROL
Maintenance of adequate inventory
To avoid production held up/ stock out condition.
To avoid customer dissatisfaction
Reduce increase in cost for emergency purchase
Avoid excessive Investment in Inventory
To reduce carrying cost
To avoid tying up of productive capital
Reduce inventory decisions for management
17. ABC Analysis
According to this approach, the items are classified into 3 categories
A Class items : 10% of item costing 60-70% of total cost Small in
number, but consume large amount of resources
B Class items : 20% of items costing 30-40% of total cost Intermediate
C Class items : 70% of items costing 20% of the total investment
Larger in number, but consume lesser amount of resources
Advantages
Strict control on item with high % value of material costs
Reduced investment in Inventory
Reduced cost of storage
18. VED Analysis
Selective Inventory control approach
Vital (V) items : Those which are necessary for the
survival of the organization as lungs and kidneys. Stock out
of above even for a short duration stops production for
quite some time .
Essential (E) items : Items which are indispensable or
necessary for running an organization. Stock out of such
items cannot be tolerated for more than few hours.
Desirable (D) items : Which are needed but do not cast
any effect on its performance.
19. HMLAnalysis
The HML classification follows the same procedure as is adopted in ABC
classification.
H = HIGH;
M = MEDIUM;
L = LOW.
Only difference is that in HML, the classification is based on unit value and
not the annual consumption value.
For examples, the management may decide that all units with unit value of Rs.
2,000 and above will be ‘H’ items, Rs. 1,000 to 2,000 ‘M’ items and less
than Rs. 1,000 ‘L’ items.
20. FSN Analysis
Here, classification is based on the pattern of issues from
stores and is useful in controlling obsolescence.
F = Fast moving
S = Slow Moving;
N = Non Moving.
21. Techniques Classification criteria Advantage
ABC Annual consumption value
Reduce total
inventory & carrying cost
VED Usefulness & importance Reduce production held up
HML Unit value / cost per unit Helps in inventory mix
FSN Based on utilization
Effective management of
stock
Prevent expiry &
obsolescence
22. Conclusion
Inventory management is an important tool in value chain
management
Helps in maintaining adequate balance between supply &
demand
Helps to gain quantity discounts
Effective inventory management leads to maximize profit &
minimize cost.
