Takt Time for Manual Assembly Process
Issue
As assembly work is done by hand, work speed may fluctuate. At times, a worker may not be able to keep up with the main assembly line and other workers may not be fully aware of the situation or the assembly pacing.
Proposal
Install a signal tower showing the work progress. By making delays clearer, awareness at the work site is improved, and supply delays are reduced. The cart travels on rails, and requires a button to send it to the next process. As the button is pressed, the signal tower is automatically reset.
