Seth's Blog : What's at the bottom of the river?

What's at the bottom of the river?

I have no idea if the bottom of the Hudson River is smooth or not. I know that on a calm day, the surface is like glass.

One reason to lower the water level of a system you count on is to see what's messing things up. You can discover what happens when you operate without slack, without a surplus... you want to know what's likely to get in the way...

This is the essence of Toyota's quality breakthrough. When Toyota got rid of all the extra car parts held in reserve on the assembly line, every single one of them had to be perfect. If a nut or bolt didn't fit, the entire line stopped. No cars got made until the part was perfect.

This seems insane. Why would you go through the pain of removing the (relatively) low cost buffer of some extra parts? The answer, it turns out, is that without a buffer, you've lowered the water level and you can see the rocks below. Without a buffer, every supplier had to dramatically up his game. Suddenly, the quality of parts went way up, which, of course, makes the assembly line go faster and every car ends up working better as well.

Fedex had to build a system far more efficient than the one they use at the Post Office. When you only have 12 hours to deliver a package, the rocks will kill you. Now, when they need to deliver something in three days, they're still way better at it than the post office is. Fewer rocks.

The purpose of sprinting without slack isn't that you will always be sprinting, always without extra resources or a net. No, the purpose is to show you where the rocks are, to discover the cruft you can clean out. Then, sure, go back and add some surplus and resilience.

Seth's Blog : Erosion

Erosion

The Grand Canyon wasn't created by an earthquake.

While it's tempting to imagine that the world changes via sudden shocks, that our culture is shifted by dramatic changes in leadership, that grand gestures make all the difference...

It turns out that our daily practice, the piling up of regular actions, the cultural practices and biases that we each choose—that's what makes change happen.

False promises and urgent reactions are a trap and a sideshow.

Seth's Blog : A tunnel is a cave with a light at the end

A tunnel is a cave with a light at the end

Just because it's dark it doesn't mean we're underground.

It often means that no one has bothered to turn on any lights.
