As you learn all the different kaizen tools and see the vast opportunities to eliminate waste, it can be exciting and overwhelming at the same time. You may be tempted to jump into the water and start swimming as fast as you can only to find the you are just treading water.
Don't try to apply all the different techniques across the entire company all at once. Pick one critical area and focus your teams effort on a single goal.
