Not IT malpractice and this where the industry diverges. IT folks usually don’t work on or understand these systems.
Which is one of MANY problems OT faces. IT best practices don’t suffice in OT and even when they do, most of these orgs are too resource hamstrung to do anything about all of the fires they have to put out.
Not to mention all of the OT vendors who flooded the market with tools instead of people being taught the boring process driven work.
