Defect classification is the process of categorizing defects or errors in products or systems based on their characteristics and impact. This helps organizations identify the types of defects that occur most frequently and prioritize them for resolution. Common categories include cosmetic defects, functional defects, and performance defects. By classifying defects, teams can implement targeted quality control measures and improve overall product reliability. This systematic approach also aids in communication among team members and stakeholders, ensuring everyone understands the nature of the issues. Effective defect classification ultimately contributes to enhanced customer satisfaction and reduced costs.
