This guide to logic mapping has been developed with the aim of giving more in-depth advice on developing logic maps to inform the planning, design and evaluation of transport interventions.
Logic mapping is a tool for articulating underlying and implicit assumptions of what changes will occur, the delivery steps which need to be undertaken to achieve the anticipated changes and the external factors which will also influence the outcome. Therefore, this guide will be of interest to policy makers, evaluators, local authorities and partnership organisations.
To promote best practice in transport evaluations the Department for Transport has published an accessible step-by-step guide to evaluation design (Guidance for Transport Impact Evaluations). A key principle within the guide is to encourage evaluation planners to clarify exactly how the intervention will deliver anticipated outcomes and contribute to wider impacts. Step 3 of the impact evaluation guidance recommends mapping the intervention logic to inform the design of the evaluation and this guide will provide practical support to evaluation planners undertaking this process.
The 3 chapters take the reader through the following step-by-step processes, with tips, ideas, practical suggestions and common hurdles highlighted throughout.
Chapter 1: Logic mapping and its uses
What are logic maps, what are their components and what is their purpose?
Chapter 2: Step-by-step guide to logic mapping
How do you go about populating each element of a logic map? Best practice, useful hints and tips.
Chapter 3: Using logic maps as part of an evaluation strategy
How can logic maps be used throughout the evaluation process? eg defining the evaluation questions, deciding on the evaluation criteria and data sources or analysing the data.
