“Garbage in … Garbage out”
Lean is about stopping and fixing issues when they go wrong: quickly and consistently, everytime.
At the heart of the Lean is the concept that if you spot an issue – stop and fix it. Letting an issue move forward without fixing the problem increases the costs, potentially allows the problem to get to the customer and kills the potential to learn fast.
Taken to the extreme, in Toyota, the idea is that anyone could stop the car manufacturing line if they located a problem. In reality, it’s slightly different than this, but the concept sticks.
If you find an issue, stop, fix it and feed it back quickly. We all learn by fast feedback, so try this and get back to the business of delivering better quality next time the task is done.
It will save hours!
