A usability review is a technique that evaluates the usability of a system or product based on a set of criteria or heuristics, without involving the actual users. It can be performed by experts or peers, and it can identify potential usability problems and suggest improvements. A usability review is suitable for situations where the availability of users is limited or impractical, and it can provide quick and low-costfeedback. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 81, section 5.3.2.2.

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

Exhibit B is the only state transition diagram that matches the text description of Acme’s elevator door rules. It shows that the doors can transition between four states: Opened, Closing, Closed, and Opening. The transitions are triggered by either commands (open or close) or sensors (opened or closed). The diagram also shows that the open command can reverse the closing state, and the close command can reverse the opening state, as specified in the text. The other exhibits do not show the correct transitions or conditions for the elevator door system. References =
