"This document provides guidance toward planning and implementing an evaluation process for for-profit or nonprofit programs -- there are many kinds of evaluations that can be applied to programs, for example, goals-based, process-based, outcomes-based, etc. ... Note that the concept of program evaluation can include a wide variety of methods to evaluate many aspects of programs in nonprofit or for-profit organizations. There are numerous books and other materials that provide in-depth analysis of evaluations, their designs, methods, combination of methods and techniques of analysis. However, personnel do not have to be experts in these topics to carry out a useful program evaluation. The "20-80" rule applies here, that 20% of effort generates 80% of the needed results. It's better to do what might turn out to be an average effort at evaluation than to do no evaluation at all. (Besides, if you resort to bringing in an evaluation consultant, you should be a smart consumer. Far too many program evaluations generate information that is either impractical or irrelevant -- if the information is understood at all.) This document orients personnel to the nature of program evaluation and how it can be carried out in a realistic and practical fashion."
