Fernando Lanzer is an expert in leadership development, team development, strategy implementation, and cross-culture issues. He designs workshops on these topics using models called the triangle, tree, bridge, and ladder. The triangle focuses on assessing the current situation, desired goals, and the process to achieve them. The tree helps make strategy clear by answering questions about clients, value, ambitions, and more. The bridge addresses understanding and working with other cultures. The ladder outlines five steps for human resources functions to progress through. Lanzer invites further discussion on these models and topics.
