“…OD is research-action oriented and favours a constant and iterative dialogue between practical and theoretical concerns. It is a field of practical application based on a process of accompaniment, initiated either internally or externally (Schein, 1999) and covering a vast panoply of activities (Carter et al, 2001(Carter et al, , 2005French and Bell, 1999;Rothwell and Sullivan, 2005) such as: organizational diagnosis (Harrison, 1999); feedback mechanisms for members of the organization such as survey feedback (Ryan et al, 2000), search conference (Cabana and Emery, 1995;Emery and Purser, 1996), coaching (Evered and Selman, 1989;Testa, 2005;Thach, 2002;Natale and Diamante, 2005), appreciative inquiry (Cooperrider et al, 2003;Egan and Lancaster, 2005;Whitney and Trosten-Bloom, 2003); and the design of interventions at the level of human processes, technostructure, human resource management and global strategy. This array of methods allows organizational actors to master new knowledge and ways of doing things.…”
