Activity 2: Wash and condition hair (10 minutes). Activity 3: Neck, shoulder, and back stress-release massage (10 minutes). Activity 4: Design the hairstyle and do the hair (25 minutes). Activity 5: Check out the guest (5 minutes). Three servers (S1, S2, and S3) offer the services in a worker-paced line. The assignment of tasks to servers is the following: S1 does Activity 1,52 does activities 2 and 3 , and 53 does activities 4 and 5 . Instruction: Round "average labor utilization", "cost of direct labor and "capacity of this new process" to 2 decimal places. a. What is the labor content? minutes per customer b. What is the average labor utilization? percent c. At a wage rate of $20 per hour, what is the cost of direct labor per customer Mr. K considers hiring a new employee to help any one (and d. only one) of the servers without changing the tasks performed per customer by each server. What will be the new direct labor? c. At a wage rate of $20 per hour, what is the cost of direct labor per customer? per customer Mr. K considers hiring a new employee to help any one (and d. only one) of the servers without changing the tasks performed by each server. What will be the new direct labor? Mr. K contemplates redesigning the assignment of tasks to e. servers. For this, Mr. K is evaluating the reassignment of Activity 5 from S3 to S1. What will be the new direct labor? per customer f. Mr. K is thinking to add one additional worker to the process. The worker would be assigned to the same set of tasks as one the current workers. First, decide which set of tasks would benefit from one additional worker, then calculate the customers per hour process capacity (customers per hour)? Suppose 4 minutes of processing time from activity 4 could be moved to activity 3 while keeping the task assignments the g. same. What would be the capacity of this new process (customers per hour)? Suppose each worker could be trained to complete all activities and they could all work independently of each other. h. What would be the capacity of this process (customers per hour)
