If possible, I'm looking for this information in the context of K-12 public education, but any public sector information regarding this subject would be a helpful starting point. I have had a very difficult time finding any research that has surveyed or discussed how ancillary services such as maintenance, finance or procurement perceive their role as comprising a meaningful part of the whole organization, and that they have a part to play in the delivery of its mission.
Thanks kindly for your help.
