Some people prefer PDSA over PDCA because it “emphasizes learning over inspection”.
Some people prefer OODA over PDCA because they believe the PDCA model is about “analysis of complicated situations”, while the OODA loop suggests “sensing of complex environments”.
Some people prefer YMCA over PDCA because it supports a “healthy body, mind and spirit”. (Actually no, I just made that up.)
I sometimes prefer LMAO because all models are wrong, though some are useful. And to me the useful ones are those that help me to change the world and enjoy my job at the same time.
If you care too much about the differences between PDCA vs. PDSA vs. OODA vs. BML vs. PSR vs. YMCA you have probably achieved too little to understand that the differences usually don’t matter.
As Jerry Weinberg said, “Don’t take your models too seriously.”
And that also applies to this blog post.
