In industrial production and test engineering environments, the documentation and categorization of recurring failures is essential for: Improving process efficiency Increasing product reliability Reducing rework and waste Supporting sustainable corrective and preventive actions Knowing how to correctly classify failures allows attacking the root of problems and building a virtuous cycle
In test engineering, especially in industrial and laboratory environments, ensuring that the results obtained are reliable, traceable, and technically valid is essential. It is in this context that the principles of the ISO/IEC 17000 series and, more directly, the ISO/IEC 17025 standard, an international reference for testing and calibration laboratories,
Just-in-Time (JIT) is a production philosophy that aims to deliver what is needed, in the right quantity, at the exact moment, eliminating excessive inventories, waste, and idle time. Its focus is on synchronizing production processes with real demand. Produce only what is necessary, when necessary — this is the principle
The FMEA (Failure Modes and Effects Analysis) or Failure Modes and Effects Analysis is a systematic methodology used to identify, prioritize, and mitigate risks of failure in products, processes, or systems. The goal is to anticipate what can go wrong, understand the effects of these failures, and take actions to
The DUT failure history is the complete record of all defects, anomalous behaviors, and test statuses that a given tested product has exhibited throughout its lifecycle — from initial testing to possible field returns (RMA). This history is essential for the identification of recurring failures, technical traceability, continuous improvement, and
Test Engineering is the branch of engineering that develops and implements systems, procedures, and tools to verify the functionality, quality, safety, and performance of a product or system. It is present in various sectors — electronic, automotive, medical, aerospace, cosmetic, industrial — and plays a critical role in ensuring technical
The 5 Whys technique is a simple and powerful root cause analysis tool, which involves asking “why?” repeatedly (five times or more) to identify the real origin of a problem. The goal is to go beyond the symptoms and find the technical and procedural root cause, enabling lasting corrective actions.
The Ishikawa Diagram, also known as the fishbone diagram or cause-and-effect diagram, is a visual tool used to identify, organize, and analyze the possible causes of a problem. Created by Kaoru Ishikawa in the 1960s, the method is widely used in quality, engineering, and continuous improvement to investigate production failures,
PDCA is a continuous improvement methodology used to plan, execute, check, and act on processes, aiming to eliminate failures, standardize best practices, and increase efficiency. It is widely used in quality management, industrial processes, testing laboratories, and production engineering. What does PDCA mean?
