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 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 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 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,
