Usability:
Usability measures how easy and intuitive the system is for users. This includes user interface design, navigation, and the clarity of instructions. Testing should involve real-user feedback and observation. Nielsen’s usability heuristics (1994) provide key guidelines. For instance, a widely circulated usability study indicated that users prefer systems that require minimal effort to learn and navigate. Testing can involve A/B comparisons to identify which design elements improve user satisfaction. -
Security:
Security encompasses the measures taken to protect the system from malicious attacks and data breaches. Testing should ensure that all data inputs are sanitized, and proper authentication protocols are in place. According to a 2020 report by Cybersecurity Ventures, cybercrime damages are projected to exceed $10 trillion annually by 2025. A significant example included testing a healthcare application for vulnerabilities, revealing weaknesses around patient data access. This raised serious concerns about compliance with regulations like HIPAA. -
Compatibility:
Compatibility is the ability of the system to work across different devices, browsers, and operating systems. Testing must confirm that the software behaves consistently regardless of the environment. A 2019 study by Zhang examined cross-browser compatibility and found that 20% of features malfunctioned under specific conditions. Therefore, testing should include a variety of devices and platforms to ensure seamless user experiences across all environments.
By examining these areas during testing, one can effectively verify that the system is functioning properly and meets user expectations.
