With any improvement philosophy, people always want the BIG improvement. When there are none to be had a re-organization or a shift in direction is implemented. This may work for a short period of time, but eventually the results normalize back to their old levels.
A uniqueness with lean is creating a focus on getting better each day. Even it if is just a second or two better. Saving 1 second each day while maintaining the savings from the previous day will yield 8.7 hrs of savings after a work year. What would you do with a full extra day of capacity?
Paul Akers has called this 2 second lean. It is extremely powerful.
Focusing on small improvements means focusing on what bothers you and your customer and fixing it. It could be as simple as always having to search for a stapler when doing paperwork. Or moving the placement location of a label. This saved a group I worked with 1 second per label…we timed it. Over the course of the year, that was a savings of over 30 hours for the team!
People don’t like to focus on small changes because it isn’t “sexy”. Guess what? Sexy falls apart quickly and usually has no substance.
Build lasting change a little at a time. It takes patience and understanding but two years from now you will have better actual results than people chasing only the “big” improvements that never get completed.
