Why is "process variability" significant in Quality Improvement?

Process variability is significant in Quality Improvement because it highlights the inconsistencies that can occur within a system, which often lead to errors and suboptimal outcomes. High variability in a process can lead to unpredictable results, making it difficult to ensure that a given service or product meets the desired standards of quality. By identifying and understanding where variability exists, organizations can take steps to reduce it, leading to more standardized processes and improved overall performance. This focus on minimizing variability is essential for enhancing reliability and ensuring that processes are efficient and produce consistent results, ultimately driving better outcomes for patients or customers.
