Let me jump in really quickly, and then I think Kathleen wants to also.
There is a bundle of issues to consider when you're thinking about the institutional home for a pay equity system. You want a system that isn't already burdened, because that results in delay. You want a system with requisite expertise that is sufficiently—indeed very adequately—resourced. You want something that is set up to be proactive, with the staffing and the resources for that. You also want a guarantee of impartiality through security of tenure and pay. Those features are the ones that should guide you in your choice of where you institutionally house the program.
