Kvalitetsteknik

Kvalitetsteknik is a field within engineering focused on ensuring and improving quality in products and processes. It integrates engineering principles with statistical methods and management techniques to prevent defects, reduce variation, and increase efficiency throughout the product life cycle. Practitioners analyze processes, design experiments, validate measurement systems, and implement controls to meet customer requirements and regulatory standards.

Key methods include statistical process control (SPC), process capability analysis, design of experiments (DOE), and failure mode and effects analysis (FMEA). Quality planning and control often follow a quality system such as ISO 9001 or industry-specific standards (for example IATF 16949 in automotive or ISO 13485 in medical devices). Tools like control charts, sampling plans, root cause analysis (e.g., 5 Whys), and DMAIC from Six Sigma are commonly used to identify and eliminate sources of variation.

Typical responsibilities for a kvalitetstekniker or quality engineer include verifying measurement systems, conducting process capability studies, performing supplier quality assessments, leading internal audits, supporting product design with quality requirements, and coordinating quality assurance activities from development through production and service.

Education and background: a bachelor’s degree in quality engineering, industrial engineering, mechanical engineering, statistics, or a related field. Ongoing professional development is common, including training in statistical methods, quality management systems, and domain-specific standards.
