Quality Improvement (QI): is the use of a deliberate and defined improvement process and the continuous and ongoing effort to achieve measurable improvements in the efficiency, effectiveness, performance, accountability, outcomes, and other indicators of quality that improve the health of a community
(R. Bialek, L. M. Beitsch, A. Cofsky, et al, Journal of Public Health Management and Practice, 2010).
Performance Management: is actively using performance data to improve the publicís health, including the strategic use of performance standards, measures, progress reports, and ongoing quality improvement efforts to ensure an agency achieves desired results (Turning Point. From Silos to Systems: Using Performance Management to Improve the Publicís Health, 2003).
Plan-Do-Check-Act (PDCA): is an iterative four-stage problem-solving model for improving a process or carrying out change. PDSA stems from the scientific method (hypothesize, experiment, evaluate). A fundamental principle of PDSA is iteration. Once a hypothesis is supported or negated, executing the cycle again will extend what one has learned (Embracing Quality in Local Public Health, Michiganís QI Guidebook).
