Process capability is defined as which of the following?

Process capability is defined as the extent to which a stable process is able to meet specifications. This concept is crucial in quality management and Six Sigma because it evaluates how well a process can produce products that meet specified limits consistently. It encompasses the idea that for a process to be capable, it must not only be stable (meaning it shows consistent performance over time) but also able to produce outputs that fall within designated acceptable limits or specifications set by customer needs or regulatory requirements.

Focusing on this definition highlights that process capability assesses the ability of the process to deliver quality results rather than just controlling or monitoring the process. This distinction is important in quality improvement initiatives since improving capability often involves process design changes, adjusting inputs, or refining technology to better align with specifications.

While there are other options that touch on aspects of process control and stability, they do not capture the full essence of what it means for a process to be capable of meeting requirements. Understanding this key aspect helps in optimizing processes for better quality outcomes.
