Question 4 Measuring Process Capability

Task 1:

An airline wants to measure its transit time performance. The airline collects 150 samples of flight transit times for a route. The summary data for these samples are:

X double bar = 245 minutes

? = 5 minutes

The required transit time is 240 + 20 minutes.

  1. What is the Process capability Ratio (Cp)?
  2. What is the Process capability Index (Cpk)?
  3. Use the reference value of 1.33 to determine the capability of the process. What can we say about this airline's transit time performance based on these 150 samples?
