Yes, wrong understood and wrong applied methodic approaches don't work.
I was over several years multiple times involved in design thinking driven Initiatives.
Sure, we tried to involve early the as-is process and technical situation. And for sure we put the real users to the center and involved the employees with deep kownledge about the subject.
There was a result about the "what" to do. But the link to the real "how" was missing.
