Joan has a small design and tailoring shop making custom outfits for women. She has two employees. Each employee only begins working on a dress when a customer order has been received and then she makes the dress from beginning to end. The average production time of a dress is 1.8 days, with a standard deviation of 2.1 days. Historically, Joan has been receiving orders with interarrival times of one day on average. The interarrival times of orders have a coefficient of variation of one. (Carry at least 4 decimal places in all intermediate calculations. Round your final answer to 2 decimal places.) What is the expected waiting time, in days, between when an order is received and when production begins on the dress? A. 9.12 days B. 6.50 days C. 1.23 days D.3.41 days
Currently a company that designs Web sites has five customers in its backlog. The time since the order arrived, processing time, and promised due dates are given in the following table. The customers are ready to be scheduled today, which is the start of day 190.

QuestionByron Sports is a manufacturer of sportswear. It produces all of its products in one department using a process costing system.The information for the current month is as follows:Beginning work in process (30% complete as to conversion cost) 12,000 unitsUnits started 90,000 unitsUnits completed and transferred out ?Ending work in process (70% complete as to conversion) 8,000 unitsCosts:Beginning work-in-process direct materials $28,800Beginning work-in-process conversion $5,040Direct materials added during month $216,000Conversion costs incurred during the month $139,200Direct materials are added at the beginning of the process. Conversion costs are incurred uniformlythroughout the production process. Costing is handled on a FIFO basis Required:a. Prepare a production cost worksheet using 5 steps approach.b. Under what conditions would a process costing system be more appropriate than a job order costing system? Explain.
I submitted this question a couple days ago. However, I am still a little confused. Here was the original question: Collins Little Company has a staff of 4 employees, each working 8 hours per day at a rate of $20/hour. Their overhead expenses are $200/day. Collins processes and closes on 12 titles each day. They are considering purchasing a computerized title search system that will allow the processing of 20 titles per day. With the new system, they could cut their staff to 2 employees working the same hours at the same pay, but their overhead expenses would double to $400 per day. 1. Compute the labor productivity with the old system (in titles / hour). 2. Compute the labor productivity with the new system (in titles / hour). 3. Compute the multifactor productivity with the old system (in titles / dollar). 4. Compute the multifactor productivity with the new system (in titles / dollar). One of the answers is: Labor Productivity = 12/(4*8) Another is: Labor Productivity =…
Johnson Fastener and Tool had a six-hour work stoppage yesterday, which means the company does not have its usual number of fasteners stored in inventory. Concerned that the inability to fulfill all current orders may have an adverse effect on some customers, Acme's account executives are notifying all customers, including Henderson Air, that there could potentially be a small delay in delivering some orders. This is an example of:
