CPK Dashboard – Manufacturing Quality, Six Sigma and the Process Capability Index

Filed under: Dashboard Screenshots — Tags: — dashboardspy @ 9:37 am

You Six Sigma blackbelts out there know all about the KPIs associated with manufacturing quality process improvement, but the rest of us need the pretty pictures to see what you mean. What better way to learn than off of a series of enterprise dashboards? Here are some screenshots of Manufacturing Dashboards that focus on part quality metrics such CPK (Process Capability Index). The dashboards are from a demo that you can try out from

This first screenshot shows the monitoring of the CPK and CP index numbers:

CPK CP Quality Monitoring

Basically, here is a quick definition of CP and CPK:

Cp = Process Capability. A simple and straightforward indicator of process capability.
Cpk = Process Capability Index. Adjustment of Cp for the effect of non-centered distribution.

This from

“If you hunt or shoot targets with bow, darts, or gun, try this analogy. If your shots are falling in the same spot forming a good group this is a high cP, and when the sighting is adjusted so this tight group of shots is landing on the bullseye, you now have a high cpK.”

Here is an enterprise dashboard screenshot showing plantwide quality monitoring:

If you drill down on the red alert indicator shown for Line 3, you see this:

Drilling down gives you the equipment statistics summary:

Another section of the Dashboard allows you to monitor many plants at once with this multi-facility view:

The following KPIs are available for each plant. They fall into the areas of Production, Financial ROI, Supplier/Customer and Quality Metrics.

Drilling down into a particular part gives you this detail page screenshot:

So what or who is The Dashboard Spy? As his about page states, The Dashboard Spy is just a guy interested in the design of enterprise dashboards. He could not find any executive dashboard design source books (or even screenshots of real business dashboards) and so set about creating his own. Finally convinced to post his extensive collection of dashboard screenshots online, he was amazed to find how popular it has become. If you have a nice screenshot of a digital dashboard, balanced scorecard, or any business intelligence graphic to share, please send an email to info _at_ Also check out The Dashboard Spy’s favorite books on business dashboards.

PS: If you find yourself part of an enterprise dashboard effort, you must study Enterprise Dashboards: Design and Best Practices for IT, the only book on actually implementing enterprise dashboards.


  1. The best “Dashboards” I have seen utilize a car (or plane) instrument panel overlay as the format for the information – for example take a Focus dashboard shot and use the instruments/information lights to show process performance…for complex processes consider the Lear Jet cockpit.
