How does The Jackson Laboratory (JAX) make decisions around promotions?

Faculty promotions are handled in a manner consistent with a university setting: publications and grant success are dominant factors. Lots of potential for promotion within the entry-level faculty cohort. Within the hourly worker pool in Bar Harbor, dominated by animal care technicians, there is a fairly standard, objective set of criteria and typically a well-documented process for employee feedback. For salaried professionals outside of the faculty/professorial ladder, promotions are uncommon and the criteria quixotic. JAX is not looking to build leaders from within, at least not to the extent that they would eventually join the Senior Management Team.
