Measurement of the scientific productivity and output of scientists. This is a concern of auditors for grant-giving public agencies and private foundations that want to ensure that their investments of funds in research grants are delivering value for the funds invested. A simple and crude measure is the number of original publications in peer-reviewed publications, presentations and abstracts in peer-reviewed scientific congresses, and patents applied for and granted. The “citation index”—the number and frequency of citation by others in subsequent publications—is an approximate measure. A more sensitive measure is the impact factor. A difficult criterion to assess is the frequency and timeliness with which original scientific work is applied successfully and with benefit by others.
