Overview#

A Reason defines a code or category for a particular event or association, specifically for losses, bonuses, off-flow, and hold operations that may happen at a Step.

Critical Manufacturing MES supports the following reason types:

  • Bonus adds quantity to a Material during or after processing. For more information, see Record Material Loss/Bonus.
  • Defect assigns defects to a specific Material. For more information, see Material Defects.
  • Hold sets a Material on hold at a specific Step. For more information, see Hold Material.
  • Loss removes or terminates quantity from a Material during or after processing. For more information, see Record Material Loss/Bonus. The Electronic Failure Catalogue (EFC) applies to Loss Reasons.
  • Off-Flow sends a Material to an off-flow or rework Flow. For more information, see Rework Material.
  • Pause pauses a Checklist instance during execution. For more information, see Pause Checklist Instance.

Why Reasons Matter in Manufacturing#

Reasons support manufacturing operations in several ways:

Quality Control and Root Cause Analysis#

  • Detect recurring quality issues and prioritize root cause analysis.
  • Improve process reliability by tracking why losses, holds, or off-flow situations occur.
  • Support systematic investigation of defects and quality problems.

Performance Monitoring#

  • Track yield loss during production.
  • Measure total loss quantity.
  • Help identify patterns and trends in manufacturing performance.

Traceability and Compliance#

  • Provide end-to-end traceability of manufacturing events.
  • Support audit-ready evidence for regulatory compliance.
  • Document why specific actions were taken during production.

Operational Efficiency#

  • Record Hold Reasons to understand production delays.
  • Monitor rework and temporary Off-Flow Reasons to improve process Flow.

Reporting and Analytics#

  • Enable detailed reporting on loss classifications.
  • Support data-driven decision-making.
  • Provide insight for continuous improvement initiatives.
