Usability Testing for Nielsen & Molich Heuristic- myassignmenthelp

Question: Discuss about theUsability Testing for Nielsen Molich Heuristic. Answer: Introduction For the evaluation of the usability of the wireframe designs the Nielsen Molich heuristic approach is being adopted. The testing would help in deciding upon the efficiency of the interface design. Visibility of system status The visibility of the system is efficiently designed. The system provides the user with the efficient information on each and every screen and provides efficient information to the user about the content of the page and provide details about the different criteria of the page such as the cart information and order details. These are updated on their own and helps the users understand the status of the process they are involved in. Match between system and the real world The match in between the system and the real world is also efficiently done. The system display message such as Welcome message for the user and also commands that helps the user in navigating through the systems. User control and freedom The design lacks in this aspect as the design does not indicate any actions that would provide the user with the user control and freedom option. In addition to this there are no emergency exists in the design and neither is there a scope to include a redo and undo feature in the design. Consistency and standards The design generally follows the platform conventions. They maintain the actual flow of a general application. The design elements also are made according to the conventional design standards. The homepage in the design displays the introduction followed by the login features and login details. In addition to this, the registration page for the system comes after the login page and this maintains the conventional approach to designing. This helps in maintaining the conventions used for the designing of the interfaces. Error prevention The error preventing option is implemented in the system to some extent. The error message Hi, Please login to use the app. You can register by clicking on the user icon above. Provides the information to the user about the login functionality of the system. This displays that the user cannot use the features of the application unless they login the systems. However, there are no additional error prevention features displayed in the design. Hence this feature is partially included in the design. Recognition rather than recall The application does not involve any concept in which the user is required to remember any of their previous action on the system. However the design displays that the user is guided in each and every step by the application itself and hence, the recognition rather than recall feature is maintained by the application. Flexibility and efficiency of use The concept of the design does not include any scope for an experienced user or an intermediate user. The system is a general e-commerce site and hence, there are scope for the evaluation of the website in this criteria. However in and an e-commerce system the experiences buyers or the frequent buyers are provided with additional benefits however no such options are presented in the design. Additionally an experienced buyer would also be able to get an information or product more easily rather an inexperienced user. Hence, the design should not be evaluated in this criteria. Aesthetic and minimalist design The design is provide with an Aesthetic and minimalist design as the dialogues in the system does not contain any irrelevant content or content that is rarely needed. The irrelevant information make website of the system large and slows down the system. Hence, the system design is efficient in this aspect. Help users recognize, diagnose, and recover from errors The system Help users recognize, diagnose, and recover from errors, there are no additional codes that the user has to go through in the error detection methods. The system also provides a constructive suggestion for the solution to the error and also displays the relevant discussions for the error. The example taken here for this context is of the error message Hi, Please login to use the app. You can register by clicking on the user icon above. Hence, the system is efficient in this regard. Help and documentation The design contains the testimonial and contact us sections. This would help the user in guiding through the website. However there are no documentation feature that would help the user in navigation through the system. Hence, this aspect of the design is partially met. However there is additional scope for improvement in this sector of the interface design. Bibliography Ali, A., Alrasheedi, M., Ouda, A., Capretz, L. F. (2015).
