I am an self-taught when it comes to Lean Production. This is one of the names given to the revolutionary (still) insights generated by the Toyota car company beginning in the 1950s. It is also called Toyota Production Method (TPM) and Continuous Quality Improvement (CQI), Just in Time, and other names.
One part of the philosophy of lean is try out the small adjustments, if they work, keep them until more adjustments occur to you. Here's an example.
I ride my bike as transportation. I have enjoyed this activity in two cities. I have to lock the bike whenever I leave to have a good chance of seeing it when I return.
This requires a lock and key. The key hangs on my lanyard along with my whistle around my neck. When I use the lock the cord wraps and hooks sometimes around anything available, causing frustration and delay.
So, I get a new bag that has a two-part key chain. The type where you can detach the keys from the ring.
Enter creativity :: I moved the detachable key ring to my lanyard.
Now, it's very easy and I had to adjust to the change (remember to use it).
That was success for about three weeks, when more creativity :: I could delete the detachable key ring and use the lanyard clip that's been there all along.
Now I lock my bike and there's no tangled lines and accessing the key and replacing it takes just a few seconds.
