There are a number of options when it comes to using software to help create a logic model. These range from generic word processing tools (Word, Powerpoint, or their Google Doc or Mac equivilants), to software that has been specifically tailored for visualising Theories of Change, like TOCO or Miradi. You should consider what resources you have to invest in software, both in terms of cost and in time to learn and use the features. If you only have a short timeframe and have simple needs, then a basic tool may suit you better than some of the more complex software available. It's important to investigate a few options and see what is going to be best for you.
Theory of Change Online (TOCO) is web-based software (no download required) that you can use to design and edit and store your Theory of Change, learn the concepts of theory of change, and capture your outcomes, indicators, rationales and assumptions in an interactive graphical environment.
An cloud-based flow chart maker with a number of usual features, including integration with programs like Visio.
Miradi is designed to provide project teams with the essential features that they need to design, manage, monitor, and learn from their conservation projects in other words, to practice good adaptive management. Currently, most conservation practitioners go through the adaptive management process either using pen and paper, or by cobbling together functions from a wide range of programs including flowcharting, mapping, project planning, spreadsheet, accounting, and other software packages. Miradi takes the right functions from each of these different kinds of programs and bundles them together in one easy-to-use integrated package.
Scapple is an easy-to-use tool for getting ideas down as quickly as possible and making connections between them. It allows you to make notes anywhere on the page and to connect them using straight dotted lines or arrows. It aims to recreate the experience of jotting down notes on a piece of paper.
The Visual Understanding Environment (VUE) is a concept and content mapping application, developed to support teaching, learning and research and for anyone who needs to organize, contextualize, and access digital information. Using a simple set of tools and a basic visual grammar consisting of nodes and links, faculty and students can map relationships between concepts, ideas and digital content.
Dylomo is a free, web-based tool that can be used to create interactive, online logic models. Its development involved a user-testing experience at the Canadian Evaluation Society conference in St. John's, Newfoundland & Labrador, Canada in June 2016, and was demonstrated at the Australasian Evaluation Society conference in Perth, Australia, 2016.
This free and open-sourced web-based tool was made by Steve Powell as a quick and simple way of creating a theory of change.
Logframer is a free project design and management application based on the logical framework approach (LFA / Logframe). Logframer was designed with NGO projects for development and humanitarian assistance in mind, but can also be used for projects in other sectors. The logframer website provides step-by-step guidance for making the most of the software to support a logical framework approach (LFA), Project Cycle Management (PCM), and Results Based Management (RBM).
