The coursework is 100% of the assessment for the module.

Learning Outcomes

1. Synthesize impact of design refinements on object oriented software quality by reviewing available literature.
2. Use evidence to analyse problems to determine appropriate object oriented methods down to detailed design.

Assessment Criteria

IMPORTANT: This is an individual assignment, all components submitted must be your own work or accredited accordingly. You are welcome to make any assumptions you feel necessary when analyzing the requirements stated in the question, but these must be clearly stated in the report.

Your report should address the following two components: –

Assignment Component 1: Research Report (min. 4000 words) (50 marks)

Assignment Component 2: Solution Design Report (min. 2000 words) (50 marks)

PLAGIARISM: It is essential to avoid verbatim reproduction of content from external sources, including web pages, books, papers, and other materials. Instead, focus on expressing ideas and concepts in your own words. If you are referring to external content, whether paraphrased or directly influenced by it, it is crucial to provide proper acknowledgment through citations.

Deliverables

The assignment consists of a research report and a solution design report, both structured according to the assigned tasks. Please follow the guidelines below when submitting your work:

• Submit your assignment via the Moodle platform.
• Ensure that all sources are appropriately cited using the required referencing style.
• Use recent, peer-reviewed scholarly references that are relevant to the topic and provide up-to-date and authoritative information.
• Include any additional relevant information, data, or supporting materials in an appendix to the document.

Assignment Component 2 (50%) – Solution Design Report (2000 words)

Component 2: Solution Design Report (min. 2000 words)

Assignment Overview:

This component is designed to assess students’ ability to analyze an existing system, propose a comprehensive redesign using modern methods, and critically evaluate their own design. It encourages the application of object-oriented principles and the use of standard design tools and methods in software development.

This section of the assignment provides a structure for Component 2 as well as guidelines to help you write the research report:
