Line Balancing - Yamazumi Chart Method

Line Balancing - Yamazumi Chart Method

Abstract:

Line balancing is a production/manufacturing/management strategy that aims to optimise the production of a product within a specific time frame.

The strategy involves assessing entire manufacturing production lines, cosntruction schedules or value chains, highlighting processes that are either constrained (inefficient) or overproducing (efficient) and rebalancing these processes and resources to smooth out production.

The Yamazumi chart is a tool that is used to visualise this strategy by identifying all sub-processes involved in a particular task, how workers are allocated to each process, the mean time taken for each task and which processes add value or not.

The chart ensures quick indentification of problems within the value chain, and enables tasks or sub-processes to be quickly redistributed between workers and for tasks that are not value-adding or waste to be eliminated from processes entirely.
