Logic model

Logic models are hypothesized descriptions of the <a href="/facts/Causality/Swh496X7">causal</a> chains in certain plans, used to show social programs of action and the results desired from them. They lead from inputs to outputs and then outcomes. Logic models can be considered a visualisation of the desired relationship between action and change in the area being evaluated. A basic narrative logic model is as follows: Input: teachers trained on child asthma; Output: children develop better skills to deal with asthma; Outcome: asthmatic children are healthier. Logic models are typically used in professional settings however can be relevant outside of the workplace for personal projects. 
Logic models usually take form in a graphical depiction of the "if-then" causal relationships between the various elements leading to the outcome but rarely can be found being used in narrative form instead. The core of a logic model is the graphical or narrative depiction, but it also comprises relevant theories, evidences, assumptions and beliefs that support the model and the various processes behind it.
Logic models are implemented by the administrative branch of employees in a workplace to plan and execute interventions, schemes and programs. They are typically employed in the public sector but are also prevalent in private firms where they are used to organize and conduct literature reviews or for employee training purposes. The domains of application for logic models are various; waste management, poultry inspection, business education, heart disease and stroke prevention are but a few common examples. Since they are used in many contexts for different purposes, the typical components, complexity and levels of detail in logic models varies depending on the literature they are found in (compare for example the W.K. Kellogg Foundation presentation of the logic model, mainly aimed for evaluation, with the numerous types of logic models found in the <a href="/facts/Intervention_mapping/hbE3zSeY">intervention mapping</a> framework).
