Quality Management

Maintain quality disciplines, tools and techniques to drive inspection data collection for Statistical Process Control (SPC).

With Quality Management from the Plex Manufacturing Cloud, you have the advantage of adding essential quality disciplines to your production processes. You use tools and techniques such as product specifications and control plans to maintain accuracy. Defect and deviation tracking as well as checksheets and process instructions are used to drive inspection data collection for SPC requirements.


Quality Management from the Plex Manufacturing Cloud enables you to meet compliance requirements with the ability to trace production from start to finish.

  • Checksheets and Process Instructions

    • Author checksheets and process instructions
    • Fully integrated with and driven from the Control Plans module
  • Control Plans

    • Help ensure compliance with quality standards by creating and managing powerful and effective, highly-detailed process control plans with detailed inspection instructions and checksheets
    • Specify sample frequency, gaging, control chart type and other quality-oriented data
    • Define control plans specific to each product or product type
    • Optionally create one or more “common” control plans to cover a whole range of processes in a generic fashion
    • View and execute control plan instructions and checksheets directly from the Control Panel and other interfaces
    • Highly integrated with product specifications
    • Is often a necessary element for quality standard compliance
  • Defect Log

    • Track production defects at the inventory container level.
  • Deviation Tracking

    • Track approved deviations from control plan dimensions or specifications during the production process.
  • Dynamic Control Plans

    • Combine the benefits of specification-level control plans with process failure mode effects and analysis (FMEA) methodology, gage repeatability and reproducibility (gage R&R) and process capability (Cp/Cpk).
  • FMEA

    Use the failure mode and effects analysis (FMEA) discipline to address questions like:

    • What can go wrong with a product design or a production process?
    • What will happen if it does?
    • What controls do we have in place to detect it if it does?
    • How should we improve the part or process?
    • Create, edit and view design and process FMEAs
    • Link FMEAs to specific products or product types
    • May be a necessary element for quality standard compliance
  • Inspection Data Collection

    • Establish and maintain a detailed list of product dimensions and characteristics
    • Assign dimension names and descriptions, gage type, target values, dimensional and attribute tolerances
    • Where appropriate, define formulae which derive variable specification limits from data such as actual chemical composition of the inventory being produced
    • Optionally specify custom gages, SPC special cause alert parameters and significant characteristic symbols
    • Link specifications to potential failure modes
    • The system records a complete history of specification changes and applicability over time.
  • Issue Management

    • Identify and record issues on which company focus needs to be maintained.
  • Part Specifications

    • This module is used to establish and maintain a detailed list of dimensions and characteristics on specific parts, including Dimension Name, Target Value and Tolerance.
  • Process Flow Charts

    • Create presentation-quality process flow diagrams
    • Diagrams are dynamic and driven directly from process routing data
  • SPC

    • Collect in-process inspection data for statistical process control (SPC)
    • Perform capability studies, dock audits, dimensional layouts, first-piece and final inspection sheets and any special user-defined checks
    • View data with on-screen charts which can in many cases be switched on-the-fly between histogram, average and range, run chart and individuals chart
    • The system automatically performs all statistical calculations such as standard deviation and process capability (Cp/Cpk)
    • Highly integrated with the part specifications, control plans and gage control
    • Is often a necessary element for quality standard compliance
  • Specification Management (Documents)

    • Manage and track specification documents such as engineering specifications, material specifications, and other external standards.
