As the Williams Bicycle Co., in Omaha, completes plans for its new assembly line, it identifies 25 different tasks in the production process. R. Don Williams, the VP-Operations, now faces the job of balancing the line. He lists precedences and provides time estimates for each step based on work-sampling techniques. Williams's goal is to produce 1,000 bicycles per standard 40-hour work week.
