Productivity levels in the boom, shipping, and maintenance departments have remained constant. However, the packaging department has recorded decreasing productivity over the past couple of years, with the result that a large backlog of finished product is typically stockpiled outside the packaging building. The morning shift of the packaging department is unable to keep up with the combined production of the sawmill and planer departments, so the unpackaged output is left for the afternoon shift. Unfortunately, the afternoon shift packages even less product than the morning shift, so the backlog continues to build. The backlog adds to ArbreCorp’s inventory costs and increases the risk of damaged stock.
