Product Quality Tracking

This ERD (see the following figure) illustrates the significant entities related to product defect tracking. Defects can be associated with service requests and can include associated activities defined to fix the defect. Associations can be defined with various product or product versions to record which are affected by the defect, which are planned to fix the defect, and which actually fix the defect. Additional relevant associations with external products can be recorded. Defects can be associated with other, related defects.
