- 1. Page | 1 Assignment 2 – Application Systems Design Report Weight: 80% Rationale: The purpose of this assignment is to demonstrate your ability to analyse and design a solution for an application system proposal. Group Work: Being able to collaborate on tasks, especially in virtual environments, is an important skill to master to ensure your success at university and in your later careers. To facilitate your development of communication and collaboration skills, you will be undertaking this assignment in a group of three (3) students. Group members must be enrolled in the same course code (i.e., 1803ICT students group together and 7610ICT students may form groups). Task: You will produce an analysis and design report for an innovative application system proposal chosen from the following five scenario options. Choose just one scenario that your group will use for this assignment. The scenario options are: 1. Virtual Reality Shopping Experience 2. AI-Powered Music Collaboration Platform 3. Smart Home Automation System 4. Gamified Task Management Platform for Freelancers 5. Blockchain-Based Digital Identity Management System Full descriptions of the scenarios are provided on the “Assignment 2 Scenarios” page in the Welcome module of the course site. Before choosing a scenario, ensure you carefully read the details of the one that interests you most. You will incrementally produce your assignment report by applying the concepts and techniques covered each week to your chosen scenario, and documenting the output of the analysis and design. It will be necessary to return to your chosen scenario’s description weekly as you work through this assignment. For each week’s course module, you are required to produce a corresponding section of your report, as outlined below. For each report section we have provided a list of possible areas you might address. You do not need to include all items, instead choose as many or as few that you feel will best evidence your analysis and design for your chosen scenario. Remember, your finished report should be logically structured, and each section should be comprehensive and form a coherent unity. Refer to the Marking Rubric for further guidance.
