Building on the iterative prototyping work of ILGC 4, this course guides students through the critical transition from a working prototype to a solution that is viable, scalable, and ready for real-world deployment. Students stress-test their solutions against the complexities of actual implementation, accounting for resource constraints, stakeholder ecosystems, regulatory considerations, and long-term sustainability. Implementation roadmaps are developed alongside pathways for scale, including social enterprise models, policy engagement, and technology transfer, with collaboration encouraged with external partners, NGOs, industry stakeholders, or government bodies where relevant. The course also introduces frameworks for measuring social impact, enabling students to articulate the tangible outcomes and broader significance of their work.
