Special Interest Groups (SIGs) are volunteer-led committees within Yayasan Salam Malaysia that focus on key issues like children, the environment, and marginalized communities. Each SIG is headed by a senior volunteer and committee who plan activities aligned with the organization's strategies. SIGs assist with headquarters projects, pursue their own initiatives, and fundraise independently. Lessons learned include strong volunteer commitment and ideas, though coordinating overlapping activities and resource scheduling across multiple SIGs can become complicated.
