A longer planning horizon allows for better anticipation of demand and resource needs, while a shorter horizon may lead to stockouts or excess inventory due to insufficient foresight.
Ques:- How would you evaluate the inventory performance ? What is Inventory Turn Over ratio and what would you recommend to increase it under a set of assumptions.
