Which aspect of work products is static testing particularly effective at ensuring?

Static testing is particularly effective at ensuring correctness because it involves reviewing work products, such as requirements documents, design specifications, or source code, without executing the actual code. The primary goal of static testing is to identify defects, inconsistencies, and errors early in the software development life cycle.

During static testing, techniques such as reviews, inspections, and static code analysis are employed. These methods allow teams to evaluate logic, adherence to standards, and proper implementation of required functions, which helps in verifying whether the work products meet the specified requirements and fulfill their intended purpose. Identifying correctness issues at this stage is crucial, as it reduces the likelihood of defects that could become more complex and costly to address later in the development process.

Other aspects like performance optimization, usability testing, and user satisfaction are typically assessed through different testing methods, such as dynamic testing, user acceptance testing, or performance testing. These approaches involve executing the software in a runtime environment and observing its behavior in real-world scenarios, which is outside the capability of static testing focused on correctness.
