Since one of the pillars of lean thinking is the visual workplace, why hasn’t problem solving in the workplace been taken to the visual level?

Flowcharts are popular visual tools that can show what’s currently happening, what could be happening, or what should be happening—a great opportunity to show where there may be a disconnection between procedures and reality. A flowchart also provides a pictorial display of where problems occur and where and how proposed solutions may or may not solve the issue.
