Many of these ideas have been incorporated into aspects of OD thought and practice in recent years, although perhaps without the specific intent to create a ‘New OD’. We argue that there are at least five contemporary OD related practices that are based on or influenced by newer theories and assumptions subsequent to the classical formulation of OD in the 1950s and 1960s. These include practices related to appreciative inquiry, large group interventions to seek common ground, changing mindsets and consciousness to achieve transformational change, addressing diversity and multicultural realities, and models of change, such as complex adaptive systems theory, that differ from the classical ‘unfreeze–movement–refreeze’ linear change paradigm.
