I have to start by saying I read the post 2-3 times because I thought you said the podcast offended you. I dont think that is the case after re-reading, but if we did please DM me. That is never the intent.
So, I look at certifications the way I look at driving school in America. Before you are licensed to drive, there are companies that offer basic driving instruction under the supervision of an instructor. There are many benefits to the student for taking the driving instruction:
- Lowers the insurance cost once licensed
- Preparation for licensing test
- Improves confidence
There are a subset of drivers that have gone through driving school, because it is not required to drive in America. There are also folks that have taken driving school that fail the licensing test. If they do pass, there are folks that took driving school with a wide variety of actual driving skill, from amazing to horrendous. The same is true of those that have not taken the driving school.
My point: the instruction you get in anything is a tool that assists. It is up to the person to apply that tool and master it in application. If you have a good CSM/CSPO/PSM/... trainer that resonates with you and helps to shape the mindset, your certification process was of high value. The inverse is also true.
