| When a situation goes wrong, look at your process and ask why. |

Lean isn’t only a mindset. It gives you and your organization tons of tools and techniques you can apply immediately to improve your business processes. One of my favorites is the 5 Whys. It’s the best demonstration I think of how in fact, people don’t fail, processes do.
In short, 5 Whys is a quick root-cause analysis. Sakichi Toyoda invented this approach in the Toyota Motor Corporation to analyze the defects in processes.
