Follow Up: Error Proofing my Keurig?
You might remember last month when I wrote about my human error in putting an upside down coffee mug under my Keurig brewer. Oops.
Mike Thelen, a good friend of mine and this blog, sent me a little gift that’s intended to prevent future mixups:
This really cracked me up… as you can see, green arrow up = good. Red arrow up = bad.
As was pointed out by a Twitter follower, when I shared this there, the color coding wouldn’t work for those who are color blind, which I’m not. The mug also has the Lean Blog logo to help tell if the mug’s right side up or not. As far as I know, my mug is a one of a kind. Thanks, Mike!
I have that same mistake since… problem solved?
