The purpose of the second assessment task is to perform, and report on a usability evaluation using a digital system that aligns with the focus of your usability principles/guidelines in the first assessment task. The evaluation should also consider user needs by creating a user persona. The critique will describe the interface, present areas that have high usability areas with design concerns. Some low-fidelity designs will demonstrate suggested fixes or improvements based upon your findings, or your own ideas given your understanding of usability. These changes can refer to specific aspects of the interface, re-designing specific functionality/tasks, or a combination of both.
Your Digital System
The digital system that you will use needs to align with the focus of your guidelines/principles presented and justified in the first assessment task. Students who do not use a system related to their first assessment task risk receiving no marks for this assessment.For example, website usability guidelines and principles require you to choose a website (maybe one fitting a particular genre, eg online shopping). If you are determined to choose a different digital system that does not match the work you have completed in Assessment 1,then you need to seek approval from the Unit Chair before starting given your evaluation criteria will be incomplete/missing. For students who have not completed the first assessment task, you will need toresearch, understand, and apply usability guidelines and principles to a related digital system. Questions or concerns over digital systems can be asked in the Assessment 2 Questions discussion topic.
Analysis and Evaluation of the Digital System
There are two main tasks associated with this assessment. Firstly, you need to complete a usability analysis of your digital system (likely to be a website/web app, software program, mobile app or game) and write a commentary on the best and worst parts of the interface.Secondly, you are required to present examples of fixed, improved or new interfaces in response to some of the findings of your evaluation.These interfaces will show the visual design and can show specific functionality relevant to your digital system from your understanding of task analysis.
Analysis of the Digital System
- Users (humans)
- Describe the characteristics of a typical user of your digital system. The characteristics of a user refer to what they need to use the digital system for. What are the main tasks/goals that users need to perform with this digital system? Users (humans)interact with digital systems via the interface. This should be written as a user persona.
- Digital system description & usability evaluation
- Provide a brief description of the digital system including the number of ‘zones’ used (specific sections), the purpose of each zone, and the general ‘look’ of the digital system’s interface.
- Using your principles/guidelines from Assessment 1, evaluate and report on the usability of your digital system’s interface.
- When assessing the usability of the interface, also consider aspects such as visibility, affordance, layout, consistency,learnability, and aesthetics among others.
- Write a short opinion about the overall usability of your interface.Suggested Interface Design Changes▪ Review your usability evaluation findings and determine parts of your chosen digital system that require some re-designing to be more aligned with your guidelines/principles. You can focus on specific aspects of the system, re-designing specific functions/tasks/task sequences, or a combination of both separate/individual screens and functions. Your ideas can also attempt to solve deficiencies in the system based upon your understanding of usability that may not have been fully covered in the evaluation given the guidelines/principles used.
▪ To illustrate the design changes, these should be low-fidelity, however, the interface and changes you make must be clear.For example, scanned hand-drawn sketches, or electronic using a stylus (Apple Pencil/Microsoft Pen), or using a design/prototyping application like Adobe XD or Figma. If you are using an application, ensure your work remains lowfidelity as Assessment 3 in your group is the opportunity/expectation for high-fidelity design.
▪ Create and present 3-4 interface design changes. If you are redesigning some functionality, each function will be counted as one change.
▪ For each suggested change, briefly re-state problem/issue and how your re-design addresses and solves the issues or flaws in the current design. You can refer to your user persona as part of your explanation/argument.
Report Content Requirements
You are to present your work as a usability evaluation report. This report will contain a number of sections including, but not restricted to:
▪ an introduction that briefly includes and defines usability, usability testing (the method/s) and the role of evaluation with reference to the type of digital system you are evaluating
▪ a description of typical users of the system and their needs as a user persona
▪ sample screens and an analysis of the usability (screenshots or photos)
▪ the re-designing of 3-4 sections or aspects of your digital system
▪ a conclusion providing a summation of the overall usability of the interface and the proposed changes
▪ a list of referencesReports similar to other students submitted work and concerns with referencing will be investigated and may lead to alleged academic integrity breaches. Usability evaluations covering aspects of Azure or AWS are prohibited.
Your submission must be in the form of a report. The size and format is up to you. The length of the report should be 1500 words (excluding references). You must acknowledge all statements and information taken from other sources and adhere to the guidelines published regarding plagiarism. All ideas and material taken from references must be cited and a full reference list must be provided at the end of the report. Diagrams and/or tables may be used if you think this will strengthen your arguments. Advice on referencing (Harvard style) and report writing is available on the Study Support site.
The assignment is to be submitted online through the assignment folder in the unit site as either a Word document or PDF.
