Quality Engineer FAQs
Quality Engineers need a combination of technical and soft skills. These include strong analytical and problem-solving abilities, knowledge of quality management systems and tools (like ISO 9001, FMEA, SPC), and an understanding of continuous improvement methodologies (such as Six Sigma and Lean). They also need to be excellent communicators and collaborators to work effectively across different departments.
QA focuses on the process used to produce the final product. It is a proactive approach aimed at preventing defects from occurring in the first place through planning and process improvement. QC, on the other hand, is reactive and focuses on the final product itself. It involves testing and inspecting products to identify defects after they have been created. A Quality Engineer's role often encompasses both QA and QC responsibilities.
