This document describes a simulation activity to build synergy between AIESEC Indonesia's Outgoing Global Cultural Development Program (oGCDP) and Communications functions. Participants are randomly assigned roles in oGCDP or Marketing and must complete tasks from the other department's perspective. The objectives are to understand challenges from a lack of synergy and emphasize that oGCDP is about sales while Communications is about strategic program marketing. The simulation involves creating marketing plans, partnerships, and addressing issues like low conversion rates to emphasize collaborative problem-solving.
