Utica Lighting Company (ULC) is a manufacturer of outdoor lighting systems for patios, walkways, and public areas. It markets its product to landscaping companies and local municipalities. ULC employs a centralized computer system with distributed terminals in the various departments. Recently the company has been having manufacturing delays and cost overruns. ULC has hired your auditing firm to assess its and internal control procedures .produced and adds the production details to the digital production schedule. The system automatically adds a record to the open work order file and sends a digital work order to the work center supervisor’s terminal and to the cost accounting clerk’s terminal. The work center supervisor accesses the work order from his terminal and prints hard-copy move tickets and material requisitions for each stage in the production process. Production employees take the materials requisitions to the storekeeper and secure the components, subassemblies, and raw materials needed to perform their production tasks. If excess materials beyond the standard amount are needed, the supervisor prepares additional materials requisitions. The employees also complete job time tickets after each stage in the process to reflect the time spent on the job. When the employees complete their tasks, they send the move tickets and time tickets to the cost accounting department. The storekeeper receives the materials requisitions and releases the materials into production. He then updates the raw material inventory records and sends the requisition to cost accounting. When inventories of component parts and raw materials fall to their reorder points, the storekeeper prepares purchase orders and sends them to the respective vendors. Vendors deliver raw material inventories directly to the storeroom, at which time the storeroom clerk inspects them and updates the digital raw materials subsidiary ledger. Each day the storekeeper prepares a journal voucher and posts to the general ledger raw material control accounts.
