Presents a framework to describe typical constraints that program evaluators face. The framework encompasses the usual evaluation costs and other factors that impede data collection or the implementation of strong evaluation designs. These are characterized as internal/substantive or external/political. (SLD)

The concept of evaluation readiness complements other evaluation planning approaches. Its basic products are the formal program definition and the data inventory framework. Ways to improve timeliness, appropriateness, and use of evaluation are also discussed. (Author/GDC)

Many evaluation researchers are now attempting to synthesize quantitative and qualitative approaches. Although such efforts appear to carry great promise, some subtleties and incompatibilities of these approaches are perhaps being overlooked. Implications for social inquiry are discussed.

Factors involved in pre-planned and post-planned evaluation of program effectiveness are compared: (1) reliability and cost of data; (2) internal and external validity; (3) obtrusiveness and threat; (4) goal displacement and program direction. A model to help program administrators decide which approach is more appropriate is presented. (Author/MH)

Strasser and Deniston's own analysis (TM 504 254) shows that post-planned evaluations are unsuitable substitutes for pre-planned evaluations. When viewed as post-experimental interviews, however, post-planned evaluations can produce valuable information which complements traditional experimental and quasi-experimental evaluations. (MH)

A between method triangulation strategy was used to evaluate a process for long-range program planning. One study team conducted interviews and the other used a mail questionnaire. The resulting problems in coordination between teams are discussed. (Author/GDC)
