Adams Manufacturing, Inc.:
Activity-Based Costing versus Volume-Based Costing
Adams Manufacturing, Inc. manufactures cooling and heating coils for several different industries. It has two plants. Jewett City Plant (JCP) is an older, labor-intensive machine shop where skilled workers use tools to perform most of the work. Greenwich Plant (GP) is highly automated and uses computer numerically controlled (CNC) machines with a small number of highly paid workers. JCP manufactures a high tolerance coil (Pa) and finishes a second one (Pb). GP mass produces two standard coils, Pc and Pd, and performs basic operations on Pb before transferring it to JCP for finishing. Production takes place in batches. Each batch is made up of one product.
