What Does the Graphic Header say About Evaluation?

The graphic superimposes a chessboard on a random walk. It symbolizes a core challenge in evaluation. The Chessboard Program outcomes are predictable in the commonsense definition of predictability.“If I provide service X, outcome A will occur.” That statement is a model: X-->A, and it is the foundation of almost every evaluation model I have seen. … Continue reading What Does the Graphic Header say About Evaluation?

Four facets of AEA. Four questions. No answers provided.

A friend of mind and I were discussing the nature of AEA. I have come to quite a few conclusions about this, but my current thinking is more in the way of questions than answers. As I see it, what’s needed is an exploration of four questions. Where does the evaluation that we do fit … Continue reading Four facets of AEA. Four questions. No answers provided.

A Complex System View of Technology Acquisition Choice

I am involved in a project that involves helping people make a single choice among multiple technologies. They must commit to one, so there is no waffling. This is one more of many such exercises that I have been involved in over the course of my career, and I have never been fully satisfied with any of them. On an intuitive level, everyone knows they cannot make the best choice, but everyone thinks that they should be able to. I finally figured out why they cannot. I don’t mean that people are not smart enough. I mean that it is impossible. The behavior of complex systems makes it impossible.

Applying the complexity concept of “sensitive dependence” to understanding how a program works

Jonathan (Jonny) A Morell President, 4.669… Evaluation and Planning jamorell@jamorell.com blog YouTube   This is the first of what I hope will be many posts that show how specific constructs from complexity science can be useful for doing evaluation. There will only be many posts if others contribute. Please do. What complex behavior is this post … Continue reading Applying the complexity concept of “sensitive dependence” to understanding how a program works
