Sometimes you need a little comic relief in your Lean presentations. This video shows the difference between a push and a pull system using a topic everyone is familiar with, the weather. While one guy relies on the weather forecast and dresses for a big storm, wearing a raincoat and umbrella, the other guy looks outside and doesn't see any rain. I love the look on the guy's face with the umbrella. How many times have our MRP production planners had that same look after scheduling to unreliable forecasts?
Don't ask me why they don't have any legs!!
