Evaluation as a field has moved beyond debating whether certain designs are good while others are bad to begin to appreciate that each of a group of designs may have its uses. The importance of good designs that reflect real-world complexities is increasingly being recognized. (SLD)

The experiences of a group of evaluators evaluating a multisite integrated human service delivery system illustrate many design and measurement considerations in the preimplementation and implementation phases of evaluation. The reemergence of human service integration approaches will make such evaluation issues increasingly common. (SLD)

This paper summarized contributors' ideas about evaluation as a field and where it is going. Topics discussed were qualitative versus quantitative debate; evaluation's purpose; professionalization; program failure; program development; evaluators as advocates; evaluation knowledge; evaluation expansion; and methodology and design.
