The 4th Social Business Design Lab took place at Yunus Centre on 4 May 3013. At the beginning, Prof. Yunus called for one minute silence for the victims of Savar tragedy. The participants from different organizations presented four social business plans. They are- DABI Powerloom Project: Creating Productivity and Generating Greater Income Through Making ‘Shawl’ presented by Mr. A F M Rezaul Karim, Reclamation of Charlands for Sustainable Agricultural Farming presented by Professor Md. Obaidul Islam, Grameen Kalyan Nobin Udyogta Project presented by Mr. Saiduzzaman and Empowering Trans-Gender People through Social Business presented by Roushan Zhumu. The Grameen Kalyan Nobin Udyogta Project is a social business initiative involving the emerging educated young generation of Grameen Bank borrower families. These youth from grameen borrower families are encouraged to become entrepreneurs (job-givers) rather than become job seekers. Four such entrepreneurs participated in the design lab program. After the presentations, there was a question and answer session. Four business plans were intensively discussed in four groups announced. Each group came up with necessary recommendations. Each project gave its time-line for implementation. Finally the participants selected one Project Bondhu (Project Friend) for each project to act as a mentor in finalizing the plan. After the social business design lab a separate session was held on Savar Tragedy and discussed the details of the rehabilitation program.
