Question:

Meena Chavan Corp's computer chip production process yields DRAM chips with an average life of 1,600 hours and o=80 hours. The tolerance upper and lower specification limits are 2,200 and 1,500 hours, respectively.

Based on the given information, the process capability ratio Cp=?

Process Capability Ratio:

The process capability ratio refers to a measure that focuses on measuring the ability of the process in order to deliver the output within a specified limit and aims to compare them concerning how they control the organization efficiently.

Answer and Explanation:

Upper specification limit (USL) = 2,200 Hrs.

Lower specification limit (LSL) = 1,500 Hrs.

Standard deviation (SD) = 80 Hrs.

Process capability ratio = (USL - LSL)/ (6* SD)

= (2200-1500)/(6*80)

=700/480

= 1.46
