Describe that for me and how you evaluate people and walk them through that process.

I believe that the learning and development, as I said, it's part of the people management and the people are the middle piece of the improvement.

So why is learning and development important? So let me explain it in a very simple analogy.

So imagine someone driving a car for the very first time, but no training, no understanding of the traffic rules, zero knowledge about the basic things like the tire pressure, engine temperature, the braking distance.

And that guy, he has the best car in the world, top performance, the best engine, the best technology, everything is perfect.

So what's happening? Most likely it will end up with a disaster.

Hopefully he will not hit someone.

What are those four levels?
