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.

The specification does not clearly define the dependencies between the power unit and the body style options. For example, it is not clear if the user can select a hybrid power unit and then choose a saloon body style, or if the hybrid option is only available after selecting a hatchback body style. Similarly, it is not clear if the user can select an SUV body style and then choose a hybrid power unit, or if the SUV option is only available with petrol or diesel power units. These dependencies affect the usability of the site, as they may confuse the user or limit their choices. The specification should specify the valid combinations of power unit and body style, and how the site will handle invalid or unavailable combinations. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 80, section 5.3.2.1.

The test basis is the collection of documents that provide the basis for testing, such as requirements, design documents, user manuals, etc. The test analyst examines the test basis to understand the scope and objectives of testing, as well as the risks and assumptions involved. This task is performed during the test analysis phase, which is the first phase of the test process. References =
