Operations Management – SCH-MGMT-670
Introduction
This case analysis looks at the two primary problems at the receiving plant no.1 (RP 1) faced by National
Cranberry cooperative during the cranberry harvesting period, viz. 1) too much waiting period for trucks
before they unload berries at the RP1 and 2) too much overtime costs. There is also a secondary problem
regarding grading of process berries. Half of the berries graded as top quality are actually not top quality and
do not deserve extra premiums paid on the top quality berries.
Problems and Challenges faced by RP1
While there is a stable demand for the cranberries, the production for the cranberries is not stable.
The proportion of water harvested cranberries is increasing and likely to stabilize at around 70%.
The plant is incurring high overtime cost
Long waiting hours to unload the crop for growers/owners of the cooperative
