Springsteen Company manufactures guitars. The company uses a standard, job-order cost- accounting system in two production departments. In the Construction Department, the wooden guitars are built by highly skilled craftsmen and coated with several layers of lacquer. Then the units are transferred to the Finishing Department, where the bridge of the guitar is attached and the strings are installed. The guitars also are tuned and inspected in the Finishing Department. The diagram below depicts the production process.
