Societal pressures include changing nature of workforce, government deregulation, compliance, shrinking government subsidies, increased importance of ethical and legal issues, increased societal responsibility of organizations, rapid political changes, and terrorism. Technological pressures include increasing innovations and new technologies, rapid technological obsolescence, increases in information overload, and rapid decline in technology cost versus labor cost.
