What is the Software Usability Measure Inventory (SUMI) used for?

The Software Usability Measure Inventory (SUMI) is specifically designed to assess software usability from the user's perspective. It provides a structured way to gather user feedback on their experience and satisfaction when using a software application. By focusing on user interaction, SUMI captures various aspects of usability such as ease of use, the effectiveness of features, and overall satisfaction.

This inventory consists of a set of standardized questionnaires that enable organizations to understand how users perceive the software. This information is crucial as it helps identify usability issues, guides design improvements, and contributes to ensuring a more user-centered software development process.

The other areas mentioned—software performance, security levels, and cost-effectiveness—do not fall within the specific focus of SUMI, which is solely aimed at measuring the user's experience and usability of software. This distinction is what solidifies the choice regarding SUMI's purpose.
