Defect taxonomies are categorized lists of defects that can be used to identify and prevent common types of errors in software development and testing. They can also be used to design test cases that target specific defect types, such as security vulnerabilities. Therefore, using a list of known defect types to penetrate the security of computer systems is an example of the use of defect taxonomies. References = Defect Taxonomies - The Practical Guide to Defect Prevention (Chapter 10), Using Defect Taxonomies for Testing Requirements, Defect Based Approach using Defect Taxonomy, Requirements-based testing with defect taxonomies

The risk impact is the measure of the potential negative consequences of a risk item on the project objectives. It depends on the severity of the defect, the frequency of occurrence, and the visibility to the stakeholders. Since requirement R1 is business critical, any failure in meeting this requirement would have a significant impact on the customer satisfaction, the reputation of the organization, and the legal compliance. Therefore, the risk impact for requirement R1 should be categorized as high or very high, regardless of the likelihood of occurrence. References =
