The term "one-shot case study" comes from Campbell & Stanley, the granddaddy of all sources for quasi-experimental designs. It is referred to by a variety of names in other sources (some methods texts call it an "after only" design). Campbell & Stanely present this design mainly to provide an example of a design that is vulnerable to nearly every threat to validity outlined in this classic work. Claudia Campbell, D.
