Executive Summary

What this assignment is about and what you want to achieve.

Introduction

Why conduct system analysis and design for a business? The purpose of your work.

The structure of your report


Where did you collect data and information for completing the report?

Company/Organization Background

What is the business and what does this business do? (A brief description of their current business operation, products and services. Please notes that you should read the case description, understand it and provide a brief summary. You shouldn’t copy the case description which we provide directly to your report. Max 100 words.)


What are some of the challenges the business (internal and external) currently facing and how they impact on overall business future development?

We have provided 10 top problems which the business is currently facing in the case description. Do you agree or disagree? You should select three which you consider are the most important for the business and explain why they are important. What are some of the opportunities when these problems are solved? How would the organisation be better off by solving this problem or taking up this opportunity? You are welcome to add on problems/issues which not currently listed, but which you consider are essential to address. You should provide reasoning.

Clearly explain the current system’s objectives and constraints. Please note: you need to read the case description to understand what the current system does.

Scope (Current system)

A written statement of functional/non-functional requirements (you are required to list them all with a

brief explanation for each of them).
Discuss the techniques of identifying the use cases.

Documentation


Data dictionary

o Complete at least THREE (3) key data flow descriptions (Logical data dictionaries)
o Data element descriptions (Physical data dictionaries, at least 1 of the key data entities) Process Descriptions
o A brief description for each of the key processes (top level processes in level 0 DFD) written in

plain English

o Write at least ONE lower level process description in structured English

Events table, DFD fragments, context diagram, levels 0 & 1 DFDs and ERD (Please see below

modelling requirements for the current system).

The appendix should also contain any other documents that might be useful for reference or too detailed or lengthy to put into the main part of the document.

*Ensure your pages are numbered for easy reference

Reference list

List all references used in the report. You have to follow the newest Harvard referencing system. Please check the Swinburne website for details.

This is a business report and should be written accordingly, i.e. directed to the customer who is “Swinburne Guru Consulting”. It should reflect your understanding of the tasks required.

Modelling for the current system

Provide a structured analysis of the functional requirements of the system presented as a set of logical data flow diagrams and prepare a data model represented as an entity-relationship diagram for the current system.

The set of data flow diagrams should include:

Identify key events and complete an event table and all related DFD Fragments

A Context Diagram: This must be for the entire Swinburne Guru Consulting (SGC) Management System. You need to show relevant external agents together with data flows between the system and the external agents.

A set of levelled data flow diagrams which includes:

1) Level 0 DFD which includes all top-level processes,
2) At least 1 top level process from this Level 0 DFD decomposed to level 1 DFD.

You will be assessed on your application of data flow diagrams according to the following criteria:
o DFD syntax
o DFD data conservation (also commonly known as “balancing” or data consistency in some textbooks)
o Quality of names
o Logical, not physical
o Quality of modelling is more important than quantity

Consistency - not only should each view (data flow, process, data store) be accurate and readable, but also the views must be consistent with each other, so the whole analysis makes sense.
An Entity Relationship Diagram (ERD): It should be a high-level data model (many to many relationship is acceptable in this unit).

Diagrams should preferably be generated by using Visio Pro, but students may use the drawing capabilities of other drawing packages subject to the approval of tutors.

Notes on formatting and structure

It is expected that all work submitted will have been edited for spelling, grammar and clarity.

Your report needs to follow our standard format. Pages need to be numbered, and your name must also appear on each page, not just the cover page. Evidence of attention to layout and structure needs to be present. The written submission is to be formatted as a report, word-processed in 12 point font and 1.5 line spacing. The word count does not include the cover sheet (*), executive summary (*), table of contents (*), introduction, main body, conclusion, references (*) and appendices (*). Please respect the word count. The sections marked with “*” will not be included in the word count.

Bonus Points (total 5 marks)

All individuals have a chance to gain bonus points if you have covered one or more of the following points:

Provide an excellent report (1 mark) or models (1 mark);

Complete additional tasks to fulfil the assignment, such as very detailed and high quality of business

overview, problem analysis, event table, and other detailed documentation. (2 marks) Demonstrate a sound research effort via high quality of references (1 mark).

Please note that you should complete the required tasks first before you attempt any extra tasks. If you achieve all basic tasks, but are of a low quality, you will not receive Bonus Points for any extra tasks you attempt. All the above will be discussed and decided by the teaching panel. We will mark on quality, not just quantity.

Warning

Any evidence of plagiarism (click on to read in detail) will result in a Fail. Collaborative discussion with other members in the unit around concepts and additional examples is highly recommended, but don’t copy.

We have adopted the Turnitin facility for assessment submission. This facility provides a             matching service which will compare Draft and Final submissions with a significant database of web-published resources, including online databases and journals. In the case of a Final submission, this will also be compared with other Swinburne and other universities items submitted previously. By making use of the draft option and receiving reports back from Turnitin, it is expected students will be able to self-assess and correct submissions. In the case of a Final Assignment Submission, no such report will be made available to students. It is the student's responsibility, however, to familiarise themselves with how to avoid plagiarism.
