When this system was created in the 1940s, it was all done with large black or white boards and chalk or pen. Now there are these boards that are available through online sources. These online boards allow the users to see exactly where the company is on its production processes through graphical displays and an integration with the ERP or other systems in the company.
These boards can all be customized to show the exact processes used for the company that is using the board, and specific cards can be created as indicators using visual tools that the users of the boards will easily understand.
