Final answer:
A process capability index value of 0.8 indicates that the process is capable of accommodating 80% of the specification limits.
Step-by-step explanation:
A process capability index value of 0.8 indicates that the process is capable of accommodating 80% of the specification limits. It is a measure of how well a process is performing in relation to its specification limits.
For example, if we consider a manufacturing process that produces a certain type of component, with a specification limit of 10 mm to 15 mm, a process capability index of 0.8 would mean that the process is capable of producing components within the range of 80% of the specified limits, i.e., within 12 mm to 14 mm.
The process capability index value of 0.8 indicates that the process has some room for improvement to meet the specifications more consistently.
