2. The new capacity will allow the company to grow which is a positive
for future revenues and profits, but it also has apparently caused two
significant problems. One is the increase in work in process
inventory, which is costly and can lead to waste, especially since the
product is paint. The quality of paint can erode if not properly sealed

the company’s customers expect the highest quality in paint. The
spoilage issues are a threat to the continued success of that strategy.
