Academic departments are political machines. Im a physician scientist and I can tell you people vastly overestimate the actual "value" they bring in with research. The department directly benefits from the salary support a nice grant brings in but that is usually still a loss against the clinical revenue that person could have generated. Most of the money from grants comes from F&A (indirect costs). At most major centers, its over 50% of the direct costs. Thing is, that goes to the institution and not the department. The departmental incentive is that they typically have quotas they are expected to meet for the SOM. Industry sponsored IITs bring in less F&A (ours is capped I think at 24%) but the direct costs which go to the department can be exponentially higher than extramural grants. As in, several of mine pay up to $15K per subject for research nursing for them to do weekly CTCAE assessments and infusions for a 5 week course of chemorads. So who does leadership value more? The guy bringing in all of the industry money or the big NCI/DOD grants? Usually the answer comes down to the background of leadership. If they are hard core physician scientists, they like to thump their chests about all of the grant funding their people are securing. If they are more clinical/business oriented, chances are they have a balance in mind and are much happier to bring in enough grant support to keep the SOM happy but are more interested in the industry/pharma funding.
Everything I just said highlights the fluid nature of "value." More often than not, politics matter more than value. Chairs really want to have people that understand the system and don't need to be "managed." This comes down to things like utilizing machines with a higher return (protons, MRL, etc) without being told, meeting retention/RVU goals, and generally keeping the people around you happy.
