Maybe a broader approach towards better usability for prospect ERPNext users but I think it might help in terms of attracting bigger organisations in the healthcare industries.
I think the fear of a big efford of switching to a new system can be smothened by presenting more advantages in regard to time consuming or complicated workflows. If the target organisation has an incentive to switch by getting a so to say quick and big ROI then they will do it no matter how steep the hill seems at the beginning. The fact that you guys were approached by a big big Dog (starting point for the whole "lets improve the HR Module story) proves that ERPNext has the potential to target the right clients.
