Continuous improvement goes hand-in-hand with the utilization of SPC techniques. It’s critical that, when SPC provides early warning of emergent issues, that key personnel are alerted and can take appropriate action to resolve the issue and prevent the nascent problem from being a line-stopping problem.
Statistical Process Control (SPC)
​
“The Bluestreak | SPC™ module is a critical component of our quality system because the instant feedback enables all personnel to actively participate in the development and improvement of our equipment processes and procedures. The run-rule function allows for easy interpretation and really simplifies the training process. The key is the instantaneous feedback to operators and inspection personnel.”

Tim Komar, Quality Manager and Bluestreak™ User
The Statistical Process Control feature in Bluestreak I SPC™ takes control plan characteristics to the next level. Any control plan characteristic can be configured for SPC. When test results are added, the SPC chart is updated in real-time allowing you to see and be notified at the time of test entry if there are any issues with your process. SPC has extensible support for statistical rules to help you spot trends before your process is out of control. Upper and Lower Control Limits are auto-calculated, but you determine when you want to tighten your control
Results are associated with a specific load/operation at the time of entry.
Key Features
-
Provides instant process feedback to inspection personnel allowing for immediate response to detrimental process variation.
-
Using the Westinghouse run rules to highlight non-random out-of-control conditions to simplify chart interpretations and reduce training time.
-
The sample size is controlled at the process level insuring the sampling plan is followed at the work order level.
-
IX and MR charts allow the plotting of single quality characteristics such as case depth and mechanical characteristics.
-
Enables predictive maintenance by using the system’s run charts to identify non-random changes in the operating parameters of key process equipment.
-
Allows for lean manufacturing total productive maintenance by providing equipment operators instant feedback allowing personnel to address negative trends before out-of-tolerance conditions occur.
-
Set control limits manually at the outset of new processes and during the initial data collection phase to provide visual aids while creating processes that are capable and in control.
-
Automatically calculate the control limits after the completion of the process development and data collection phases.
-
Recalculate the control limits with the click of the finger after process improvement activities.
-
Personnel responsible for developing processes select the operation where data collection occurs.
-
Simplifies root cause analysis when non-conformances occur by providing data from key operating systems.
-
Improves repeatability and reproducibility of inspection equipment by using the SPC programs during the calibration and verification processes.
-
Summary statistics provide critical values such as Cp and Cpk, allowing inspection personnel to efficiently report certification and shipping documents.
