Lean is like when you clean up your room and only keep the toys you really love. You put away the ones you don’t play with much, so your room has more space, and you can find your favorite toys easily. Lean is about making things simple and not having too much stuff around.
Think of lean as when you make a sandwich and only use the ingredients you like the most. You don’t put too much ketchup or too many pickles, just the right amount so the sandwich tastes perfect. Lean is about using just what you need and not wasting anything.
Another way to think of lean is when you draw a picture and only use the colors you need to make it beautiful. You don’t use every crayon in the box because that might make the picture messy. Lean means using what you need to make something work well without extra clutter.
