Which chart is most suitable for recording the movements of the left and right hands of a worker performing a bench assembly task, so that the motions can be examined for balance and unnecessary movement?

A two-handed process chart is most suitable. It records what the left and right hands do side by side at a workplace, which lets the analyst see idle hands, holding and unbalanced motion. The other charts cover the wider process or movement paths.

Explanation

A two-handed process chart, also called a left-hand right-hand chart, records the activities of each hand against a common time scale at a single workplace. This allows the analyst to spot idle hands, holding and unbalanced motions. An outline process chart shows only operations and inspections across the whole process, and flow and string diagrams show movement paths.
