“…Two decades ago, Beer and Walton (1987) pointed out that as OD approaches permeated general management practice in organizations, "the field no longer has professional boundaries" (p. 340). More recently, some authors (Worren, Ruddle, & Moore, 1999) have argued that OD should be subsumed into "change management," whereas others have objected to this approach (e.g., Farias & Johnson, 2000;Hornstein, 2001). Beckhard (2006) defines OD as a "planned change effort" that is "managed from the top" (p. 3) of an organization and is a systemwide initiative aimed at improving organizational effectiveness and health.…”
