But even if you can simplify the reporting burden, I'm back to the issue of benefit. But I can pick those faculty members out of a lineup right now. Any department chair who can't do that ought to give up the job. Obviously, having such data strengthens the hand of managers who need to address those problems. But the overwhelming benefit to having this information lies in using it to align the effort distribution of the many hard-working faculty members who want to contribute more, but are laboring in areas where they are unlikely to be successful.
Research is a good example.
Some of that, maybe a significant portion, is unlikely to result in future funding. Institutions can ill afford presently to continue that level of support.
