Continuous improvement or Cl is an approach to improving quality in an organization's processes on an ongoing basis. Three key components contribute to Cl success: (1) draw on the knowledge and abilities of employees at all levels; (2) focus on customer needs; and (3) use data in a scientific approach to decision making. A long-term effort, not a short-term fix, the classic Cl cycle is Plan, Do, Study, Act. Health care organizations are finding a good fit for Cl in clinical applications. Improved patient care through efficient, consistent processes is one of the immediate, obvious benefits of Cl. The data collected can also validate decisions from a financial standpoint and provide necessary Information to regulatory agencies. Over the longer term, applying Cl data and understanding customer needs can help to develop efficient, user oriented facilities. The chief payback, however, is an organization that is flourishing because it meets the needs and expectations of customers—patients, physicians, employees, and the community.
