4-6 What is a Processing Department? Any location in an organization where materials, labor or overhead are added to the product. The activities performed in a processing department are performed uniformly on all units of production. Furthermore, the output of a processing department must be homogeneous.

4-24 Equivalent units are the product of the number of partially completed units and the percentage of completion of those units. We need to calculate equivalent units because a department usually has some partially completed units in its beginning and ending inventory. Equivalent Units of Production
