Scala Legal adopts an interdisciplinary and participatory approach, combining qualitative, quantitative, and systemic methods across its three axes.
Axis 1 draws on systemic thinking, inspired by Donella Meadows, to map the access-to-justice ecosystem with field actors, and mobilises narrative interviews and an adapted Business Model Canvas to trace Casa Legal's effects on its stakeholders.
Axis 2 applies causal inference methods and a comprehensive cost-benefit analysis, including indirect costs and distributional effects, with particular attention to mechanisms of non-take-up of rights.
Axis 3 combines case study analysis of comparable social innovations with a co-constructive approach, aiming to understand the conditions under which integrated legal aid can take root in different local contexts, rather than simply seeking to replicate an existing model.
