ESS Support Guide 1.2 - Developing a Logic Model

Published29th May 2014

This is a practical guide that focuses on how you put together a basic logic model to help you think about your aims, outcomes and activities. A logic model tells the story of your project or programme in a diagram and a few simple words. It shows a causal connection between the need you have

identified, what you do and how this makes a difference for individuals and communities. The guides comes out of work that ESS did with funding from NHS Health Scotland to help build understanding about logic modelling. For that reason it focuses on health but the concepts are relevant for any subject area.


This guide provides an introduction to Logic Models, how they can help and two models that are frequently used for evaluation. These include the Weaver’s Triangle and the Wisconsin Model.


Evaluation Support Scotland (ESS) works with voluntary organisations and funders so that they can measure and report on their impact.

Its aim is to make evaluation valuable, relevant and proportionate. Information about the services it provides are available on the ESS website
