10. Dropping a Product Line The key is on the change in net income as a result of dropping the product line. If net income increases, do it; if not, don’t do it!

11. Dropping a Product Line: Example Single Step (7-6)

12. Beware of the Cost Allocation Death Spiral! When dropping a product or service, beware of allocating common fixed costs. These costs are not incremental and are therefore irrelevant. They just end up being allocated to other products which in turn may appear unprofitable. Beware!

14. Decisions Involving Joint Costs Joint products Joint costs Example: raw milk is processed into the following joint products: cream, skim milk and whole milk. The stage of production at which individual products are identified is called the split-off-point.

15. Allocation of Joint Costs Common input costs must be allocated to joint products for financial reporting purposes. Joint costs are not relevant to individual products beyond the split-off-point. Joint costs are relevant to decisions involving the joint products as a group.

16. Decisions Involving Joint Costs: Another Example

17. Additional Processing Decisions And Joint Costs Joint costs are not relevant to the decision. At the split-off-point, the only factors that matter are additional revenues and additional costs. Joint costs incurred prior to the split-off point are sunk and don’t change.

18. Qualitative Considerations In Decision Analysis The non-monetary factors are also important to the decision analysis. Some fixed costs continue regardless. Morale may be affected. Outsourcing can be more flexible. With outsourcing, a certain level of control is lost.

19. Appendix: The Theory of Constraints (TOC) The Five-Step Process: Identify the binding constraint. Optimize use of the constraint. Subordinate everything to the constraint. Break the constraint. Identify a new binding constraint.

20. Appendix: Implications for Inspections, Batch Sizes, and Across the Board Cuts Inspections: should take place before transfer to the constrained department. Batch Sizes: when the production process IS the binding constraint, large batches may be beneficial. Across the Board Cuts: labor/cost cuts should be precise. General, across the board cuts involving cuts to the constrained department have negative profit affects.

21. Appendix: “You Get What You Measure” Performance measures drive the behavior of managers.

28.  Quick Review Question #4 Joint costs incurred in a joint product situation: Are incurred before the split-off point. Are incurred after the split-off point. Should only be allocated based on physical attributes. None of the above.

29.  Quick Review Answer #4 Joint costs incurred in a joint product situation: Are incurred before the split-off point. Are incurred after the split-off point. Should only be allocated based on physical attributes. None of the above.
