What is the behavior of the raw material batch temperature?
Based on the data provided and analyzed on an average and range process behavior chart, raw material batch temperature is predictable with an average of 93.81 degrees and average range of 2.84 degrees. See the chart,”Raw Material Batch Temperature.” Q: What is the capability of batch temperature for this process based on the stated specifications? A: For this process, Cp = 0.53 and Cpk = 0.37. The chart “Capability Analysis of Raw Material Batch Temperature” shows that the natural process limits of 86.3 degrees to 101.3 degrees are almost twice as wide as the specification limits. In addition, the average batch temperature is a little over one degree below the target of 95 degrees. Q: If raw material batch temperature is a critical contributor to the breakage issue with customers, what should be the focus of improvement for this process by Sergio and the team? A: Sergio and the team must first get the average temperature up to 95 degrees and then work to reduce the routine variation in
