The Process Capability Index (Cpk) is a statistical tool used to measure how well a process can produce output within specified limits, indicating the process's ability to meet customer specifications. It compares the spread and centering of the process distribution to the specification limits, providing insight into potential improvements and process stability.

Specification limits are the boundaries set by customer requirements or industry standards that define the acceptable range of variation for a product or process. These limits are crucial in quality control and process management, ensuring that outputs meet predefined criteria for performance and functionality.

Process stability refers to the consistency and predictability of a process over time, indicating that the process operates within set limits without significant variation. It is essential for ensuring quality control and efficiency in production and service delivery, as it allows for reliable forecasting and continuous improvement.
