Improved layout - cross-trained workers can assist each other. Figure (a) 10 10 Improving Layouts Using Work Cells Current layout - straight lines make it hard to balance tasks because work may not be divided evenly Improved layout - in U shape, workers have better access. Four cross-trained workers were reduced. Figure (b) U-shaped line may reduce employee movement and space requirements while enhancing communication, reducing the number of workers, and facilitating inspection 11 11 Staffing and Balancing Work Cells Determine the task time (Also called .
