Manufacturing Quality Control

Manufacturing Quality ControlAIS has been committed to quality since its founding and has renewed that commitment through the use of Total Quality Management (TQM). This concept of performing operations to deliver and correct defect-free products the first time is reflected in each employee’s work and attitude and in all of our operating principles.

Supplier Corrective Action Request (SCAR)

Streamlined SCAR

  • AIS utilizes SCARs/CAPAs reports in addition to performing root cause analysis, following assigned follow up actions while effectively tracking and routing cases from initiation to closure
  • Supplier scorecards: AIS scorecards measure key performance indicators (KPI) and track improvements over time, supporting sound decision-making based on data
  • Supplier audits: AIS provides capabilities to plan, schedule and conduct audits, allowing audit results to be analyzed and enable initiation of follow-up activities such as corrective action requests and re-audits

Corrective Action

Review non-conformance and customer complaints

  • Non-conformance procedure
  • Actions to stop the use of reject or suspect items
  • Actions to correct the problem
  • Checked following rework
  • Do a product recall or retro-fit
  • Decide the cause of the problem
  • Decide an appropriate course of action to stop the problem from re-occurring
  • Put the plan into action
  • Ensure that the action has solved the problem

Preventive Action

  • Review potential problems
  • Decide the potential cause of the problem
  • Decide an appropriate course of action to stop the problem occurring
  • Ensure that the preventive action has solved the potential problem
  • Preventive action procedure
    • Analyzing data and setting objectives
    • Clarifying customer requirements 
    • Applying a proven corrective action
    • Being aware of changes
