| As discussed in Chapter 7, statistical process control (SPC) allows a company to monitor process and statistically understand the capability of a process and make adjustments before problems occur. The variety of applications for SPC is enormous. Honda uses SPC as well as other data collection and analysis approaches to maintain quality levels for many different aspects of their cars. | VIDEOspc1 |
| As an interesting example, Honda measures and monitors the speed a door has to be closed in order for it to latch. A sensor is used to find the exact lowest speed required to latch the door. | VIDEOspc2 |
| The door closing data is analyzed and monitored using SPC to ensure that fluctuation is only random. Histograms are used tracking the data over time. Process capability measures are also tracked. | VIDEOspc3 |
| One door that takes too much effort or speed to close the door shows up as an out of control data point on the SPC chart. A cause for that was a fixture that was not centering the installation of the latch correctly. Being able to identify the problem and eliminate the cause prevents the problem from re-occurring and tightens the process capability. | VIDEOspc4 |
