1) Inventory change:
End inventory ─ begin inventory 0 6,500 books 7,800 books
2) Excess production (%)
Production ÷ sales 26,000 ÷ 26,000 32,500 ÷ 26,000 33,800 ÷26,000
1.0 1.25 1.3
• A ratio of ending inventory to beginning inventory, as suggested in the book, is not
possible because beginning inventory was zero, so we substituted change in inventory
level.
For these nonfinancial measures to be useful they must be incorporated into the reward function
