Abstract
The author agrees that single-case evaluation should be reexamined. He suggests that the conclusion drawn from the limitations of single-case design, as performed today, should be to redefine issues and strategies so that more emphasis is placed on integration of research and practice. The article (re)defines empirical practice as being continuously informed and guided by empirical evidence that is gathered and processed systematically. The focus suggested for empirical practice is on individual practitioners within social service agencies. The article presents a conceptual framework to guide the formulation of questions relevant to empirical practice on the agency level.
