By reviewing and reflecting on Schein's works on process consultation and clinical perspective in field work, this article notes and tries to deal with the facts of self-involvement of an organization development practitioner. The authors choose the perspective of praxis-oriented philosophy to reflect the field works of others and their own. And through the discussion on issues of who and how to owns the organization, they argue that not only the founders and executives, but the laborers, managers and even also outsiders might have the right to discourse on the living culture. Therefore, researchers/practitioners and collaborators regain their proper roles to involve themselves into the OD practice. Furthermore, they elaborate a sub-cultural encounter process as an inquiry method to initiate those radical change/improvement in cultural beliefs.
