The capability ratio is the inverse of the Cp index. Remember that the Cp index is the specification spread divided by the process spread of six standard deviations. Flip that formula around and you would be dividing the process spread by the specification spread. In the case of a capability ratio, you would be looking for a smaller-is-better characteristic. With the Cp index, you are looking for a larger-is-better characteristic.

As mentioned in the course, there are two ways to make a bad part, or to make for an unhappy customer experience when dealing with continuous data. Either the process variation centering is off, or the dispersion (fatness, or slop in the process) is too wide. A capability study will tell you with two numbers represented by either Cp Cpk, or Pp Ppk whether your process is capable of meeting customer requirements in either the short term or the longer-term.
