The document discusses the values and ethics of organizational development (OD) practitioners. Traditionally, OD values have focused on humanism, trust, collaboration and self-control. Recently, values have also emphasized improving organizational effectiveness and performance. Joint values of humanizing organizations and improving effectiveness have received support. Challenges include conflicts between employee needs and organizational needs. Practitioners must have political skills to manage external relationships and value dilemmas. Ethical issues center around potential client abuse and letting personal values interfere with practice. Dilemmas include misusing data, technical ineptness, power/coercion, and conflicts in values/goals between the practitioner and organization.
