Failure to comply this requirement will result in a failed assignment. Unit Learning Outcomes: LO3 Undertake a software development lifecycle. LO4 Discuss the suitability of software behavioural design techniques. Assignment Brief and Guidance:

Analyze the requirements that you identified in Task 1 using a combination of structural and behavioral modelling techniques that you have learnt. Scope: You only need to construct following items for the system. You will have to include:

• Use Case Diagram for the whole system.
• Use Case specification for 2 Use cases.
• Context Diagram for the whole system.
• Data Flow Diagram – Level 0 for the whole system. ERD for the whole system. For each diagram, you will have to explain properly. Word limit: 1000 – 1200 words. Task 3 – Design Based on the analysis result, discuss how you would conduct the design phase:

1. Discuss how the user and software requirements are addressed in the design phase.

• You will explain how Mock-up, and Wireframe are used in the project. You should include some of the mockup or wireframe (at least 5) design of the Tune Source project to justify that it matches users’ requirements.
• You will explain which architecture (client – server, n-tier, microservices, etc.) is suitable for the project with clear illustrations and why.
• Then you will address which technical solution stack could be suitable to implement the project with clear explanations.

2. Discuss how activity diagram and pseudocode are used to specify the software behaviour.
3. Discuss how UML state machine can be used to specify the software behaviour. Differentiate between FSM and extended FSM using the case study.
4. Discuss how the data-driven approach improves the reliability and effectiveness of software. Word limit: 800 – 1500. Task 4 – Software quality management
5. Discuss two software quality attributes that are applicable to the project.
6. Discuss two quality assurance techniques that can help improve the software quality in the project.
7. Discuss how the design techniques and approaches that you have used can help improve the software quality. Word limit: 400 – 1500.

Learning Outcomes and Assessment Criteria (Assignment 02): Learning Outcome Pass Merit Distinction LO3 Undertake a software development lifecycle P5 Undertake a software investigation to meet a business need. P6 Use appropriate software analysis tools/techniques to carry out a software investigation and create supporting documentation. M3 Analyse how software requirements can be traced throughout the software lifecycle. M4 Discuss two approaches to improving software quality. D3 Critically evaluate how the use of the function design paradigm in the software development lifecycle can improve software quality. LO4 Discuss the suitability of software behavioural design techniques P7 Explain how user and software requirements have been addressed. M5 Suggest two software behavioural specification methods and illustrate their use with an example. M6 Differentiate between a finite state machine (FSM) and an extended-FSM, providing an application for both. D4 Present justifications of how data driven software can improve the reliability and effectiveness of software.

ASSIGNMENT 2 ANSWERS

P5 Undertake a software investigation to meet a business need. P5 Undertake a software investigation to meet a business need.

1. Business needs analysis Business Need: This project has been initiated to increase sales by creating the capability of selling digital music downloads to customers through kiosks in our stores, and over the Internet using our website. Business Value: We expect that Tune Source will increase sales by enabling existing customers to purchase specific digital music tracks and by reaching new customers who are interested in our unique archive of rare and hard-to-find music. We expect to gain a new revenue stream from customer subscriptions to our download services. We expect some increase in cross-selling, as customers who have downloaded a track or two of a CD decide to purchase the entire CD in a store or through our website. We also expect a new revenue stream from the sale of music download gift cards. Through business need and business value, we can see that they need an effectively developed Tune Source project management software system. This management software system will help them control the music trading system more easily and conveniently. 2.Stackeholders and their roles in the Tune Source Project Project Sponsor: Carly Edwards, Assistant Vice President, Marketing.

4. Data Modeling (Entity Relationship Diagram – ERD Figure 4 - ERD for the whole system P7. Explain how user and software requirements have been addressed
5. Wireframe design A wireframe is a visual representation of the fundamental structure of your website or app. Each one is used to describe how a product works as well as how various views interact with one another (what happens when you click a particular button). Most decisions about what (content/features) and where to display them on the website or app are determined during this phase. This phase does not address the product design. On the website, users can log in, register, and access details regarding Tune Source's policies. On Tune Source, users can view the newest or most popular tracks and contact the business for assistance. 1.1. Site map
