What is Logic Model .
OBNs (Oriented Bayesian Networks) can be seen as a special typology of Logic Models, which have been known for more than 20 years as visualisation support tools for planners, policy designers and evaluators.
Depending on their intended usage, four distinct types of Logic Models are known, which can become relevant for policy analysis:
- Theory based (describing the Theory of Change or the Logic behind a certain intervention, e.g. a policy or programme or project. This is the rationale for activity design or the link between problems and solutions)
- Result based (emphasizing the consequences of an intervention, such as its outputs, outcomes and impacts. Here the relevant link becomes that between activities or events and their expected or predicted implications)
- Resource based (where the focus is set on the use of resources to perform certain actions for obtaining certain purposes. This is particularly important for evaluators)
- Chained or scaled (reflecting a continuous improvement process or the dependency of a certain activity on the results of some previous ones).
