Innovation processes in complex challenges, such as the design of a foster care system, require developmental evaluation approaches that allow for adjustments in real time and learn from the barriers and perceptions of the agents. ALC has supported the AFE (specialised family foster care) programme through workshops, training and methodological tools, facilitating adaptive management and promoting continuous learning. This approach has strengthened Agintzari's internal capacities, connected initiatives in a systemic strategy and adjusted the programme to territorial contexts to improve its implementation.
