Workload and pace should fit the physical demands of the task. Organise work to minimise multiple handling and improve flow: deliver raw materials mechanically to where they are used, use mobile plant such as roller pallets or wheeled cages, process and package in the same place, locate storage near distribution, spread work across the day or week to avoid peaks, minimise storage and extra handling, and ask suppliers to deliver in a form that needs no further handling, such as flat packs on a vertical frame. Workers should not work at the limit of their ability, and work rates should be set in consultation with workers and HSRs: let workers control pace for critical or physically demanding tasks, allow line speed to be adjusted when products or materials change, provide buffers to take material off-line (watching for extra handling), and make sure pay structures do not push workers beyond their capacity or to skip breaks.
