The fact that people do something stupid and attribute it to a scientific discipline which suggests they shouldn't do it does not discredit that discipline.
Similarly, the Ariane 5 disaster doesn't mean that the idea of measuring the physical world with science is wrong.
There's nothing wrong with Taylorism. It works very well in a variety of fields (e.g. Uber and Amazon use Taylorism very effectively to manage their line workers). The fields where Taylorism isn't used (e.g. software development) are far less reliable and effective - Amazon can guarantee that your package will arrive in 2 days, can you guarantee that your software team will ship on time?
I wouldn't say that Taylorism is why those workers succeeded.
I'd say that those workers were successful in spite of Taylorism. Don't fall into the trap in thinking that just because a methodology was applied, that it contributed to success.
The best evidence I can give in support of this is Deming:
Lots of early physics was also not done very well, lots of fudges, etc. Does that discredit the idea of applying science to particle movements? Does Freud discredit the entire idea of psychiatry?
Physicists kept doing science, and it got better. Actual proper science has developed to the point where the computer I'm typing this on has a complex network of billions of logic gates which operates correctly billions of times a second. I can reasonably expect the CPU to continue to work for decades.
When managerial "scientists" can achieve anything even remotely comparable to that level of reliability and reproducibility, it will be time to take it seriously as a science. Until then, it just isn't one.
Many fields don't give that same level of reliability and reproducability; climate science, psychology and environmental engineering are all in the same boat. Guess none of them are sciences.
