During gemba visits, keep practicing seeing how mura (unlevelness) creates muri (overburden) and then muda (waste).

Or, the other way around, when looking at muda (waste), look for muri (overburden) and the mura (batching) that causes it.

How do I reduce buffers to zero?
Shouldn’t we learn better forecasting first?
