they both can’t mentally co-exist
both the top of your internal list
they’d fight and cuss and rudely swear
without caring if it was fair
but both have a secret shame
they’re both the same! both to blame!
both things people do and think
when they try and make waste shrink
Six sigma is still shit though
A few months ago some man I was speaking with said if he was reading a blog or something and came across anything in it trying to distinguish between or put down either lean or systems thinking, trying to work out which one is best, he would immediately switch it off and go somewhere else. He had no time for that. I was impressed but disturbed, as I quite like putting the boot into lean myself.
To recompense, here is my poem about lean/systems thinking using Daleks and Cybermen. It’s a metaphor.
