In which phase of the quality improvement cycle is variation typically addressed?

The phase of the quality improvement cycle where variation is typically addressed is measurement. This phase focuses on collecting and analyzing data to understand the levels of variability present in processes or outcomes. By measuring data, organizations can identify trends, patterns, and variations that may indicate areas for improvement.

Quantitative metrics and statistical tools are often utilized during this phase to isolate variability, differentiate between common cause (inherent to the process) and special cause variation (due to specific, identifiable factors), and gain deeper insight into process performance. Addressing variation effectively allows teams to focus on improving the processes that are not performing consistently and helps in establishing standard operating procedures that reduce unwanted variability.

Through measurement, teams can make data-driven decisions that enhance quality and effectiveness, laying a strong foundation for the subsequent phases of planning, implementation, and review.
