Organizational Development (OD) SIG: Informed Consultant

In 2026, the GCATD Organizational Development (OD) Special Interest Group is excited to bring you the Global OD Competency Framework series. This internationally recognized framework outlines the core knowledge, skills, and behaviors that define effective OD professionals and provides a common language for the practice of organization development. 

This meeting, led by Mary Tettenhorst of Impact Talent Strategies, wraps up our Global OD Competency Framework series. Informed Consultant centers on professional consulting excellence grounded in self-awareness, ethical practice, and continuous learning. Topics include building strong consulting relationships, applying emotional intelligence, and staying current with evolving OD knowledge and methodologies. Attendees will reflect on how lifelong learning and reflective practice strengthen consulting impact and support sustained organizational growth.
