Jody Hoffer Gittell

Jody Hoffer Gittell,PhD, is a professor of management at Brandeis University’s Heller School for Social Policy and Management.  She founded the Relational Coordination Research Collaborative, bringing scholars and practitioners together to help organizations build relational coordination for high performance.  She co-founded a university spinoff called Relational Coordination Analytics Inc. offering measurement and intervention support to organizations seeking to improve their performance, and serves as its Chief Scientific Officer.Gittell has developed a theory of relational coordination, proposing that highly interdependent work is most effectively coordinated by frontline workers with each other, their customers and their leaders, through relationships of shared goals, shared knowledge and mutual respect, supported by frequent, timely, accurate, problem-solving communication.  The theory of relational coordination has two central propositions: 1) relational coordination drives quality and efficiency performance outcomes along with client and worker well-being, under conditions of interdependence, uncertainty and time constraints; and 2) organizational structures support or undermine relational coordination and its associated performance outcomes, depending upon their design.  Gittell’s relational model of organizational change has extended the theory to address how organizations and their stakeholders increase relational coordination to achieve their desired outcomes, proposing three types of interventions needed to do so – relational and work process interventions, as well as structural interventions.Gittell’s research is published in a wide range of scientific journals, for example Management ScienceOrganization ScienceAcademy of Management ReviewJournal of Applied Behavioral ScienceHuman Resource Management JournalHuman Resource ManagementIndustrial and Labor Relations ReviewHealth Services ResearchJournal of Nursing ManagementMedical Care, Health Care Management Review, Journal of Interprofessional Care,and Journal of Air Transport Management.  She has published five books, most recently Transforming Relationships for High Performance: The Power of Relational Coordination(2016).  Gittell received her PhD from the MIT Sloan School of Management and taught for six years at the Harvard Business School before joining Brandeis in 2001.  She currently serves on the Board of Trustees of the Endowment for Health, as Treasurer for Seacoast NAACP, and on the Editorial Review Board of the Academy of Management Review.

Often barefoot, with one of her two-year old twin sisters on her back, Yarden walked at night more than 450 miles across the Sudan desert. After spending a year in a Sudanese refugee camp, she and her family were airlift to the state of Israel.

In Israel, she started attending school – learning for the first time in her life how to read and write at the age of 14. In 2005, she completed her Ph.D. in education at Tel Aviv University, becoming the first Ethiopian woman to earn a doctorate in Israel. In 2012 Dr. Yarden Fanta-Vagenshtein completed her post-doctoral fellowship at Harvard Graduate School of Education in the Human Development and Psychology Department.

She has spoken to national and international communities and organizations alike inducing Sydney Opera House in Australia, Parliament in London and on Capitol Hill in the United States, Synagogues, Churches and Women’s groups.
