Gen brings the fresh viewpoints of the young adult to content provided by Jarman International KK. He is also helping Jarman reach a larger audience and advises on growth and expansion. He describes Jarman International as “JI’s effectiveness emulates from its amoeba-like foundation, allowing for direct and grassroots contact with partners. Efficiency in staffing and meetings and a strong focus on attaining solid results to contribute and serve our partners are two of the many ways we realize our effectiveness. However, an effective executive always leads an effective organization. Thus, JI’s effectiveness does not result entirely from its structure, efficiency, or focus on results and contributions. JI’s effectiveness results from the effective executive who keeps the company on track as she astutely guides it forward. Even the great Peter Drucker would agree with me on that”.
