Monitor Processes in Real Time

Identify nonconformances in real time and prevent defects

To minimize the cost of quality, more and more companies are adopting preventative and predictive methods for manufacturing quality control. Real-time SPC software is a proven, fundamental tool used to detect, and ultimately prevent, process errors that lead to defects, scrap or waste. WinSPC's real-time SPC control charts graphically display real-time, actionable information to operators and managers. This empowers personnel to detect and correct out-of control situations, minimize variation, and continuously improve the manufacturing process. The result? Higher quality products and a more cost-effective, capable process.


  • Minimize variation
  • Prevent defects
  • Reduce scrap, waste, rework
  • Improve manufacturing yield
  • Empower personnel with actionable intelligence
  • Promote Lean Manufacturing


Two SPC Control Charts Visualize your process quality on the shop floor using real-time control charts
Using WinSPC's real-time control charts, shop floor operators and managers can monitor a process to ensure that it stays in control.

Simple Quality Control Chart Interface Win shop-floor acceptance with WinSPC's simple operator interface
For many companies, the biggest hurdle to product and process improvement is motivating the workforce to accept change or learn a new technology. This is especially true if the technology requires shop-floor operators to learn computer software. To address this, WinSPC offers three data collection interfaces--all capable of being mastered in minutes regardless of an operator's level of computer expertise.

  • Standard: the standard data collection interface simply requires an operator to key in a value and press the Enter key.
  • Blueprint: the blueprint data collection mode shows a picture or drawing to guide the user through the data collection process.
  • Spreadsheet: the spreadsheet mode allows operators to enter multiple readings in any order.
Instantly launch electronic instructions, diagrams, pictures, or other documents
Empower your operators with one-click access to electronic work instructions or other relevant documents, enabling them to quickly and independently solve problems and react appropriately to process issues.

Train workers in 30 minutes or less
WinSPC's simple operator interface allows you to train shop-floor operators in about 30 minutes or less.

Prompt operators to add notes, assignable causes, and corrective actions

Configure pop-up windows that require shop-floor operators to respond to user-defined alarms by adding notes, assignable causes and corrective actions. Optionally, store and record this information securely in WinSPC's system event log.

Define your own screen layout
WinSPC gives you the power to layout the data collection interface to meet your shop-floor needs. You can choose to display one or more types of SPC charts in the same window, display calculations, show/hide items and more.
Right-click to toggle views and display data in different charts
Interactively display and analyze your data in any WinSPC chart. Simply right-click on a chart and choose a different real-time SPC chart from the list.
Scroll to view data from the "beginning of time"
WinSPC charts include a scroll bar that enables users to immediately view all data collected for a part characteristic. Simply right click and choose "scroll bar" from the list to easily review all data collected for a characteristic.
Set fixed control limits or automatically recalculate control limits
WinSPC allows SPC professionals to set fixed control limits or have control limits recalculated every x subgroups collected. Administrators have the power to reset control limits at designated intervals, enable the system to intelligently recalculate limits, or "lock-down" control limits--giving SPC professionals the flexibility to meet a variety of SPC requirements.
Save time using built-in support for standard SPC rules--or create your own
WinSPC offers built-in support for Western Electric, Nelson, and Shewhart rules. Or, use a point-and-click interface to define your own rules for custom alarms.
Calculate, combine, manipulate, and respond to data as it is collected
Use WinSPC's equation builder to execute simple or complex calculations from raw data, such as translating readings from millimeters to inches, calculating fill weights and tare weights, or deriving and charting geometric volume from raw dimensional data. The advanced tagging and logic functions enable users to generate a number of automated, conditional responses from various inputs. For instance, you can define a specification limit for a part based upon its name or lot number.
