Successful organizational improvement involves four basic questions: what is the business about; what type of organizational culture exists; how is the work performed; and what type of leadership exists within the organization. These four questions relate to the purpose, culture, and leadership of the organization, and the processes the organization uses to accomplish its objectives. Effective organizational change requires that all four are understood and aligned. This paper discusses the components of successful organizational re-engineering and addresses the issue of organizational culture and how it relates to leadership and strategy. Includes 5 references, figures.
