Assignment 1 - System Modelling

Summary of Assignment
Based on a Case Study, students are expected to draw and discuss: An Analysis Class Diagram, a Communication Diagram, and a Sequence Diagram. Students are also expected to discuss and evaluate the usefulness of UML diagrams and a CASE tool during analysis and design.
Diagrams should be created in Enterprise Architect and inserted into a Word or PDF file to accompany the discursive aspect of the assignment.
University policies on late submission of coursework and plagiarism will be strictly adhered to for this assignment.
This is an individual assignment. This part of the coursework represents 100% of the module mark. The marking schemes (the last two pages) indicate how marks are given for each aspect of the work.

Learning Outcome 1: Apply up to date structured techniques to produce analysis and/or design models for a given case study problem
Learning Outcome 2: Have a comprehensive understanding of the role of the systems analyst/ designer, the context in which the systems development activity takes place and the professional standards that are applied to the activity

Assignment Detail - Tasks

Based on the Swift Distribution Ltd. (SDL) Management System (attached as Appendix A), complete the following tasks:

Part 1. Use Case Realisation for the ‘Allocate Truck to Driver' Use Case Analysis Class Diagram

a) In your own words, briefly describe what is meant by an Analysis Class Diagram, and how class diagrams can be useful in systems analysis and design (max 100 words, +/-10% tolerance).

b) Draw an Analysis Class Diagram for the ‘Allocate Truck to Driver' Use Case, using the Use Case description given. This should include all required boundary, control and entity classes with their associations and attributes. Your diagram should be drawn using the Enterprise Architect software and copied and inserted as a picture into your document.

c) Write a brief summary of the decisions made whilst drawing the diagram, and your reasons for making those (max 150 words, +/-10% tolerance).

Communication Diagram

a) In your own words, briefly describe what is modelled in a Communication Diagram, and how Communication Diagrams can be useful in systems analysis and design (max 100 words, +/-10% tolerance).

b) Draw a Communication Diagram for the use case in your diagram that corresponds most closely to the use case ‘Allocate Truck to Driver', using the Use Case description given. This should include all control, boundary and entity objects involved in the scenario and sufficient detail of the messages to show that the interaction is feasible and would meet the system requirements. Your diagram should be drawn using the Enterprise Architect software and copied and inserted as a picture into your document.

c) Write a brief summary of the decisions made whilst drawing the diagram, and your reasons for making those (max 150 words, +/-10% tolerance).

Part 2. Sequence Diagram

a) In your own words, briefly describe what is modelled in a Sequence Diagram, and how Sequence Diagrams can be useful in systems analysis and design (max 100 words, +/-10% tolerance).

b) Draw a Sequence Diagram for the use case in your diagram that corresponds most closely to the use case ‘Allocate Truck to Driver'. This should include all control, boundary and entity objects involved in the scenario and the sequence of interactions that take place in order to meet the system requirements. Your diagram should be drawn using the Enterprise Architect software, and copied and inserted as a picture into your document.

c) Write a brief summary of the decisions made whilst drawing the diagram, and your reasons for making those (max 150 words, +/-10% tolerance).

Part 3. Evaluation
Enterprise Architect is a CASE tool. In your own words and using examples, briefly describe what a CASE tool offers during analysis of the World-Wide Tours scenario, and what tasks the CASE tool supports. Give your own evaluation of how the role of an analyst/designer is supported by a CASE tool. Discuss how UML modelling supports the analyst/designer (max 750 words, +/-10% tolerance).
