At Health Innovation East developing and using logic models and theory of change is central to our work to support planning and delivery of implementation and evaluation projects. At the start of projects, facilitating a logic model with partner organisations, staff teams and key stakeholders fosters a collaborative process and provides a structured approach to identify and agree what an intervention looks like on the ground (what activities, resources are needed and being delivered). This in turn is applied to build consensus of what the intended outcomes and impact are, and how these can be evaluated.
Logic models and theory of change methods are used widely, and their value in supporting planning for delivering and evaluating projects, programmes and pathways is well established. Whilst key components in a logic model or theory of change include identifying inputs, activities, outcomes and the relationships between these to understand how an intervention may work (mechanisms for change) – their use and format can be tailored to the needs of the project and users of the information. We draw on our extensive experience of these tools to work flexibly to help design an approach and visuals that are bespoke to individual projects and teams’ priorities and contexts.
Our team work with projects to co-design the best approach and outputs and can combine use of different methods and mapping tools to meet stakeholders’ needs.
We recently completed a project with Hertfordshire Partnership University NHS Foundation Hospital (HPFT) to evaluate a new suicide prevention pathway that aims to create a structured and joined-up service to ensure people at risk of suicide get the support needed. Key to this project was our use of a logic model framework, the ‘Research Implementation Logic Model’ (1), to allow us to gather relevant information about factors influencing pathway implementation and to rapidly mobilise the evidence and insights gathered to help inform adaptation and improvement. We facilitated regular workshops with staff to support adaptive learning and improvement, with the visuals created through the logic modelling central to being able to share and discuss emerging insights.

We worked with three early-stage innovators as part of the Essex Care Tech Challenge Fund to support them to develop a logic model for their intervention – with a particular focus on potential pathways, associated assumptions and outcomes. Using a logic modelling approach and co-development sessions we were able to support them to test their assumptions and develop a range of hypotheses for evaluating the impacts of the innovation.
“On behalf of the Supersense team, just wanted to write a big note of thanks for yesterday’s Theory of change workshop. You have certainly stimulated a lot of thinking on our end! Thank you for walking us through the process, your expert facilitation and for the upfront thinking you did relating to our project. Look forward to executing some of the activities we discussed”
– Matt Ash, Chief Technology Officer, Supersense Technologies.
Feel Good Suffolk is the county’s healthy lifestyles service, funded by the Public Health team at Suffolk County Council, supporting residents to stop smoking, manage their weight and be physically active. It is delivered through a unique partnership model involving all of Suffolk’s District and Borough councils. Health Innovation have been commissioned to co-design an evaluation framework and to evaluate the impact Feel Good Suffolk it is having for the population of Suffolk. We will complete an initial evaluation of the service over a two-year period ending December 2026. As part of a developmental evaluation approach, we are facilitating Theory of Change and Ripple Effect Mapping workshops, alongside actor mapping, surveys and interviews to gather rich insights from multiple staff and service users about their experiences and views of Feel Good Suffolk services and impact. Using mapping approaches will be key to visualising and understanding relationships between activities, resources, and impact within this complex system-wide service. Early feedback from staff involved has already highlighted the value in early mapping workshops.
“Collaborating with Health Innovation East has been instrumental in helping us think more purposefully about our impact beyond traditional KPIs. Their support is enabling us to embed reflective practices, capture meaningful outcomes, and use evaluation as a powerful tool to shape and improve our services.”

Developing and using logic models and theories of change provides a powerful foundation for effective project planning, delivery and evaluation. These tools bring clarity to complex initiatives by mapping the relationships between resources, activities, outcomes and impact, helping teams articulate how and why change is expected to happen. By fostering shared understanding and collaboration among partners and stakeholders, logic models ensure that everyone is working towards common goals and using evidence to guide decision-making. They also create a living framework for reflection and learning, supporting adaptation as projects evolve. Ultimately, the value of logic models lies not just in the final diagram, but in the conversations and insights they generate – strengthening coherence, accountability and impact across programmes and systems.
