Software Usability Measurement Inventory (SUMI)

The Software Usability Measurement Inventory (SUMI) is a standardized questionnaire used to evaluate how user-friendly and easy-to-use a software application is. It gathers users’ opinions on aspects like how efficiently they can perform tasks, how satisfied they feel using the software, and whether they find it helpful and enjoyable. By analyzing these responses, developers can identify strengths and areas for improvement, ensuring the software aligns better with users’ needs. SUMI provides a reliable, objective way to measure software usability, supporting ongoing enhancements and better user experiences.
