In process quality management, what is indicated by the term "variability"?

The term "variability" in process quality management refers to the inconsistencies in output that occur during the production or service delivery processes. Variability can manifest in various forms, such as differences in product quality, timing, or performance. It is crucial to recognize and manage variability because it can directly impact customer satisfaction, efficiency, and overall operational effectiveness.

Understanding variability allows organizations to identify sources of quality issues and implement measures to minimize variation in processes. By striving to reduce variability, businesses can achieve more consistent results, improve quality, and enhance their competitiveness in the market. This concept is fundamental to quality management practices, including Six Sigma and Total Quality Management (TQM), which focus on reducing defects and ensuring that processes operate within defined parameters.
