A lot of educational software companies are making a lot of money promising school districts they can help schools meet the mandates of "No Child Left Behind". So Congress funded a large study to see if students who used this software did better than those who didn't. No difference. Oops!
Some of the software companies suggest that teachers are the problem, because they're not using the product correctly. Now who's fault is that?
In marketing we own the entire customer experience. And if they don't use it properly, we have to fix it right away. Maybe it's training, how to guides, or changing the product. And sometimes, no matter what, the product doesn't lead to predicted results. In that case, figure out what it does do, and position the product crisply for that, or kill it.
But blaming the users? That's just lazy.
