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
The Reference Unit is a device known as GOLDEN Unit or SILVER Unit, used as a reliable standard to validate the operation of test benches, fixtures, and industrial automation systems. These units represent a product with validated and stable behavior, allowing verification if the test environment is operating correctly —
Industrialization Engineering is the area responsible for transforming a developed product into something ready to be produced on a scale, with quality, repeatability, and efficiency. It acts as a bridge between R&D, production, quality, purchasing, and testing, ensuring that the product is industrialized in a feasible, testable, and documented manner,
Quality Engineering is the branch of engineering responsible for ensuring that products, processes, and systems meet technical, regulatory, and customer requirements. It operates transversally across the entire production chain — from development to post-sales — promoting reliability, traceability, and continuous improvement. Quality Engineering ensures that what is designed, produced, and
The 8D (Eight Disciplines) is a systematic approach to solving complex problems, especially effective for recurring or critical non-conformities in industrial environments. Originally developed by Ford, 8D is now a global reference for structured corrective actions, with traceability and organizational learning. The 8D goes beyond just correcting the problem: it
The test report is a technical document that records, proves, and organizes the data obtained during the execution of a test on a product, system, or process. It is essential to validate technical compliance, ensure traceability, and support audits or quality analyses. In modern industry, especially in regulated environments or
The MES (Manufacturing Execution System) is a real-time production control and management system responsible for connecting the shop floor with planning (ERP), quality, and engineering systems. It allows monitoring, tracking, documenting, and optimizing production execution, ensuring full visibility of what is happening on the line. Function of MES in the
The Pareto chart is a statistical tool used to identify and prioritize the main causes of failures in a process. It is based on the Pareto Principle (80/20), which states that about 80% of problems come from 20% of the causes. When applied to test engineering and production, the Pareto
Measurement is the technical process of quantifying a physical, chemical, or logical quantity by comparing it with a known standard. It is the basis for validating products, processes, and systems — ensuring quality, safety, traceability, and regulatory compliance in industrial, laboratory, and clinical environments. In practice, there is no reliable
Test software is an essential tool to automate, standardize, and record verification and validation processes in various sectors: industrial, scientific, laboratory, automotive, medical, aerospace, and technical services. Definition A test software is a program developed to control measurement instruments, execute automated test sequences, capture data, and generate reports reliably. It
