## Appendix A
* Evaluate data security controls to ensure the confidentiality, integrity, and availability of sensitive healthcare data. Test encryption algorithms, data masking, data-at-rest protection, and secure transmission protocols to protect data in transit and at rest. * Test APIs for security vulnerabilities such as improper authentication, authorization bypass, and data exposure risks. Verify secure API design, input validation, access controls, and the encryption of sensitive data transmitted over APIs. Usability Testing:
* Establish clear usability goals and objectives based on user needs, expectations, and system requirements. Define the measurable usability metrics such as task completion time, error rates, and user satisfaction scores to evaluate system usability. * Identify target user personas representing different user roles, demographics, and skill levels within the healthcare context. Tailor usability testing scenarios and tasks to the needs, preferences, and workflows of each user persona. * Develop a usability test plan outlining the scope, objectives, methodologies, and test scenarios for usability testing. Define the usability test tasks, scenarios, and success criteria to assess system usability effectively. * Recruit representative participants from the target user population to participate in usability testing sessions. Ensure diversity in participant demographics, roles, and experience levels to capture a broad range of user perspectives. * Set up a dedicated usability testing environment that closely resembles the production environment in terms of hardware, software, and user interfaces. Provide necessary equipment, facilities, and tools to support usability testing activities. * Design usability test scenarios and tasks that reflect common user workflows, tasks, and goals within the medical information system. Include tasks such as patient registration, appointment scheduling, record retrieval, and data entry to evaluate system usability. * Encourage the participants to verbalize their thoughts, feelings, and actions while performing usability test tasks using the think-aloud protocol. Capture user feedback, observations, and insights in real-time to understand user behavior and interaction patterns. * Analyze usability test results and user feedback to identify usability issues, pain points, and areas for improvement. Prioritize usability issues based on severity, impact on user experience, and the frequency of occurrence for remediation. * Document usability testing procedures, findings, and recommendations in detailed usability test reports. Provide clear and actionable recommendations for addressing identified usability issues, enhancing system usability, and improving user satisfaction. Compatibility Testing:
* Identify the target environments, platforms, devices, browsers, and operating systems that the medical information system needs to support. Define the compatibility requirements based on user preferences, organizational standards, and industry best practices. * Test the medical information system across popular web browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera. Verify that the system's features and functionalities work consistently across different browser versions and configurations. * Test the medical information system on various operating systems such as Windows, macOS, Linux, iOS, and Android. Validate compatibility with different operating system versions, editions, and configurations to ensure consistent performance and functionality. * Test the medical information system on different devices such as desktop computers, laptops, tablets, and smartphones. Verify compatibility with various screen sizes, resolutions, input methods, and device capabilities to provide a seamless user experience across devices. * Validate compatibility with different hardware configurations, peripherals, and accessories commonly used in healthcare settings.
