This document outlines the scope and goals of a project to increase the inventory turn of Caterpillar spare parts. The current inventory turn is 2.31, below the budgeted goal of 4 for fiscal year 2015-2016. High inventory levels have resulted in approximately Rs. 12.63 crores in interest costs over the past 9 months. The goal of the project is to reduce average inventory from Rs. 100.29 crores to Rs. 66.6 crores in order to save Rs. 4.24 crores in interest costs by the end of fiscal year 2015-2016.

Delivered during SAPICS 2016, a leading event for supply chain professionals, held at Sun City in North West, South Africa.
In the past, the Demand Driven Institute (DDI) have developed Demand Driven Material Requirements Planning (DDMRP) and a Demand Driven Operating Model (DDOM) that suits these Complex Adaptive Systems and have proved that it works for all material in the Supply Chain from primary raw materials to retail, through manufacturing and distribution. More recently, to complement DDMRP and the DDOM, the development of Demand Driven Sales and Operations Planning (DDS&OP) and the Demand Driven Adaptive System (DDAS) now gives us a complete demand driven planning and control system from Strategy, through Tactics to Operations. This new material will now be taught in the recently released DDI certification – Certified Demand Driven Leader (CDDL). Let us show you how you can quickly move from the traditional “Push and Promote” methods to the Demand Driven “Position, Protect and Pull” method and take the lead in your industry.

3. PROJECT SCOPE
TEAM SELECTIONPROJECT PLAN
OPPORTUNITY STATEMENT
GOAL STATEMENT
BUSINESS CASE
Increase Caterpillar Spare Parts Inventory Turn (ITR)
High Temp. & Exhaust, Non Moving and Protective Stock of Caterpillar Spare parts
leads to an average month end Inventory of Rs. 100.29 Crs (Approx.) which in turn
results to high interest on inventory carrying cost.
The focus of the project is to maintain Allocated, Non Moving, Protective and
Consignment stock at optimum level which will help to reduce interest burden and
enhance Inventory Turnover (ITR), without effecting existing service levels.
The Project has direct implication on quality & cost of PQVC matrices.
The Project will result to an estimated Level1 benefit of Rs. 4.24 Crs by reducing
interest burden on average inventory holding cost.
Our Current (April– Dec‘14) Caterpillar Spare Parts Inventory Turn is 2.31 against
budgeted growth plan of 4 for FY 2015-16. The current interest on inventory holding
for the past 9 months has been approximately Rs. 12.63 Crs. which has an adverse
impact on the bottom line.
Opportunity exists to reduce average Inventory from Rs. 100.29 Crs to estimated Rs.
66.6 Crs, thereby saving interest (@12.6%) on inventory carrying cost by
approximately Rs. 4.24 Cr during 2015-16.
Y: Increase Parts ITR from 2.31 to 4 and thereby reduce interest cost by Rs. 4.24 Crs
within 2015-16.

Pareto Chart of Territory Wise Jan-Dec'14 Avg. Inventory
Stock Value, COS & ITR by Territory (Excluding MARC)
The 80-20 Rule shows that the
Highest Stock Value lies at Taratolla &
South East & North Central; Highest
COS is at South East, North Central &
East & the Lowest ITR is for Taratolla,
North Central & North.
From the above Charts we can sight that
the Highest ITR & Lowest Inventory is
for East Territory, whereas the highest
COS lies at South East.
Focus Territories for TIPL are North & North Central, also includes
Taratolla Stock and this fact is confirmed by the Peretos too.

32. ROOT CAUSES OF INCREASING PARTS INVENTORY
1. Advance / Manual Procurement because of Wrong anticipation of
Customer Order, wrong recommendation from CSE or procurement
done against Bargain Offer
2. Protective Stock / Float / CAT Recommended Order / PSP / NPI Parts
3. Discrepancy in Min / Max Ordering. Warranty Parts also Captured under

4. Customer not lifting parts/ Customer Orders cancelled/ Parts return by

5. Lack of monitoring Open WO leads to increase in Consignment
6. Physical Stock discrepancies in Inventory
7. Parts not timely returned to Principal
8. PSSR/ PSM Skill Gap
9. Parts not returned to Principal
33. IMPROVEMENT SUGGESTIONS RECEIVED FROM TEAM
1. Accountability for each and every process should lie with concerned individual,
failure to maintain the same would initially subject him/her to warning and further
failure to display accountability should subject him/her to severe proceedings.
2. One major root causes is missing – “Customer and Service Parts Return”. Mr.
Saibal to share such cases where failure (increase in Inventory) is due to parts
returned by either customer or service team. Once receipt of such cases, the
root cause would be incorporated in ISHIKAWA and FMEA.
3. Inventory to be distributed to 4 territories instead of lying at Central stock so that
the concerned territory should be responsible.
4. Territory Heads to be made accountable for the inventory of their respective
territories and also should be responsible for the P&L Statement of the same.
This would enable central parts team in effectively monitoring the parts stock at
territory level. If required, resources from the central parts team would relocate
across territories for effective monitoring and procurement of parts accordingly.
5. The project needs to be presented to SKC Sir and his opinions needs to be
sought on further proceedings
