“Line balancing connects the amount of labor to the production rate of demand in a precise manner via standardized work,” explains Smalley. “Supervisors at Toyota, for example, have to work with team leaders and team members to adjust manpower based upon calculations involving takt time and standardized work charts. This avoids not having enough operators on the production line when demand increases or excess labor on the line when demand decreases.”

This can cause a build-up of WIP at one station, while another station may run out of parts or materials to work on.
