Social Innovation Laboratory II deepens skills in designing, developing, and prototyping social innovation projects. Students progress from diagnosis and ideation to the structured design of solutions, integrating planning, objective-setting, intervention models, and initial feasibility testing. The course also begins linking this work to the dissertation/final project. By the end, students should be able to structure an evidence-based and participatory intervention proposal; develop medium-fidelity prototypes and test functions and hypotheses; define objectives, expected results, and monitoring indicators; produce simple and realistic implementation plans aligned with identified needs; assess the social, ethical, technical, and economic viability of proposed solutions; involve stakeholders in co-creation and validation; and integrate laboratory outputs into the early stages of the dissertation/project
