What is WAMMI primarily used for in software testing?

WAMMI, which stands for Web Application Measurement Initiative, is primarily focused on assessing the quality of web applications from the end user's perspective. It provides a framework for evaluating user experience and satisfaction based on their interaction with the application. This is particularly important in today's software landscape, where user experience is critical to software success.

By using WAMMI, organizations can gather valuable insights into how users perceive the usability and functionality of their applications, allowing for improvements that directly enhance user satisfaction and engagement. This focus on user perspective distinguishes WAMMI from other testing approaches that may primarily target performance metrics or technical defect analysis.

The other options pertain to different objectives in software testing, such as measuring performance, which focuses on the system's efficiency, or defect classification and root cause analysis that aim at identifying specific issues within the software. However, WAMMI is uniquely positioned to emphasize the user's viewpoint in evaluating application quality.
