Machine: You track equipment maintenance and respond to unexpected failures. Regular calibration and preventive maintenance are crucial for consistent output.
Metode: You update processes and standard operating procedures as needed. Any revision to assembly steps or inspection protocols must be documented and communicated.
Man: You monitor planned and unplanned changes in personnel. Operator training and role changes can affect process stability and product quality.
Material Changes
You must evaluate every material change for risk. A new supplier or altered raw material can introduce variability. For example, a capacitor swap—even with matching specs—may alter Berøringsstrøm or electromagnetic compatibility, risking device failure. Medical Adapter Tech always issues a PCN for any material change, ensuring you receive timely notification and supporting robust risk mitigation.
Machine Changes
You maintain equipment to prevent breakdowns and ensure productivity. Any machine upgrade, replacement, or maintenance event triggers a review. You document these changes and assess their impact on process capability. Medical Adapter Tech’s tiered change control system ensures every machine change is traceable and compliant.
Method & Man Changes
You update methods and procedures to reflect best practices. Any change in assembly sequence, inspection criteria, or operator assignment must be controlled. You involve operators in equipment maintenance, enhancing accountability. Medical Adapter Tech tracks all personnel and procedural changes, issuing a PCN for each event.
The Risk of “Silent Changes”
Silent changes pose a significant threat to product integrity. You may encounter undocumented adjustments—such as a quiet switch in component brands—that seem minor but can lead to major quality issues. For instance, swapping a ceramic capacitor without proper notification can result in EMC failure, jeopardizing patient safety and regulatory compliance.
