The Logic in Logic Models Part 1: Extending Models in the Directions of Less, and More Specificity

I’m working on a series about the logic that can/should be contained in logic models. This is the first in the series . It’s message is that the range of knowledge that can be reflected in a model can be extended in two ways. One is toward less specificity and detail. One is toward more specificity by designating connections in AND/OR terms. Either tactic can be appropriate, depending on the circumstances.

Two Complexity Constructs to Reorient the Logic of Planning and Evaluation

Recently I was asked to prepare a brief presentation for people in the prediction business – planners and evaluators whose work was preoccupied with some form of the question: If I do this, what will happen? The audience brought a traditional if > then logic to the way they answered this question. They knew that … Continue reading Two Complexity Constructs to Reorient the Logic of Planning and Evaluation

Project Schedules, Program Models and Complexity: Linking Across Three Domains

PDF version: Schedules_logic_models_complexity_Morell_2_18_22 In 2018 I published an article making the case for using project schedules (in the form of PERT and Gantt charts) as logic models (Morell, 2018).[2] I offered two reasons for doing so. Using a project schedule as a logic model can reveal unique insight. Because planners and managers pay more attention … Continue reading Project Schedules, Program Models and Complexity: Linking Across Three Domains
