From evidence to impact: reclaiming evaluation as a means to an end
Lígia Teixeira, Founder and Chief Executive of the Centre for Homelessness Impact

Evaluation has never been more sophisticated, yet many challenges it seeks to address remain stubbornly persistent. Across sectors, we generate high-quality evidence, but too often struggle to translate it into meaningful, sustained impact. The risk is not just a lack of rigour, but a loss of connection to purpose: the way evaluation is used within systems can allow it to become an end in itself, rather than a means to improve lives.This keynote argues for renewed focus on evaluation as a discipline of impact. Drawing on international efforts to tackle homelessness, it explores how outcomes are shaped not by individual interventions alone, but by the systems in which they operate. Without a systems lens, even strong and diverse forms of evidence – quantitative, qualitative and lived - can lead to fragmented action, missing the broader dynamics that ultimately determine success.

The keynote reflects on how evaluation can better connect global insight with local context, enabling faster learning while respecting place-based realities. It also argues that effective systems prevent harm before it occurs, rather than responding once it is entrenched.

This is a call to re-centre evaluation on its core purpose: not just to understand the world, but to change it.
