It's called the "Delaware Cost Study." Your google search may be more productive than my cursory one, but mine turned up this lucid summary:
The Delaware Cost Study began in 1992. The quantitative portion of the Delaware Study seeks to answer: “Who is teaching what to whom, and at what cost?” While the information provided in the quantitative portion of the Delaware Study is quite useful, the qualitative dimension of the study seeks to measure selected facets of out-of-classroom faculty activity. The objective of the qualitative study is to create an inter-institutionally comparable set of measures that describe what faculty do outside of the classroom.
