2. •Vehicle Parts Supplier
Company •Competing on Price Basis
•Focus on small volume products
•Carburetor and Fuel Injection Division
Division •Five Production Departments
•Custom/ Standard Products – Made to Order
•Uniform plant-wide labour and overhead cost
Costing •Allocation among jobs on basis of labour hours
•Monthly variations
3. •From uniform to department wise hourly rate
•Single cost centre to Multiple (5) cost centres
•Rationale: Variation of labour skill and overheads
•Indirect Costs: Eg. Heating cost distributed on basis of
cubic feet of space

5. •Base reference – CS29 Injectors, Spare Parts for
Inventory, Work for other divisions
•Substantial change from old to proposed methods
•Insignificant difference between the 2 new proposals
– July volume similar to Normalized volume
•Cost of these products more: use of more machining
hours
•Different set of products: drastically less cost

6. •Refer Excel Sheet
Analysis
•Single Cost Centre: Cost substantially decreases with
new machine introduction
•Machine purchase in one department affects all
departments
•Multiple Cost Centres – Cost almost same, though
labour hours reduced
•Depreciation of machine also taken into account
•Department specific investments affect only that
department
7. • CFI handles overflow capacity
Outside Depts. • 32% Increase in Costs!
• Already being charged more than if work done in-house
Production • Views change as pointless
• Feels paperwork will increase
Manager of CFI • Seems not to be clear with the method
Sales Manager
• Concerned about price change
• Only bothered about end profits
8. Product pricing
◦ Better because costs are distributed based on the
operation performed on it
◦ Corrections of imperfections; custom/ standard
products
◦ Feasibility?
Cost Control
◦ Since the cost can be traced back to the operations
for individual products, it helps in better cost control
Inventory Valuation
◦ More representative as the new method allows better
tracing of cost
9. Charges to outside department
◦ 32% increase in cost
◦ Depends on the accounting method used by
them
Judging departmental performance
◦ Better since the cost analysis can be done based
on the operations performed
Diagnostic uses of cost data
◦ Helps in better tracking and planning
◦ Look at departmental improvements
