short Enterprise Systems course. You have now returned from your course ad would like to demonstrate
your learning. Create an e-portfolio to provide a synopsis and reflection on your learning during
the course. You have been requested to document your learning in a portfolio that can be displayed on
your company’s intranet or knowledge portal. This way, the entire organization can access the document
and share in your newly acquired knowledge.
This assessment task will address the following ILOs:
• Evaluate and Integrate several information sources in analysing Enterprise Systems
• Describe the role of enterprise systems as part of the larger IT infrastructure of large scale organisations.
• Identify relevant considerations in the implementation of Enterprise Systems.
• Demonstrate communication skills to present a coordinated, coherent and independent exposition of knowledge
and ideas in dealing with Enterprise Systems.
Time allocation: Approximately 30-40 hours
Weighting: 30%
Submission: Using your student e-Portfolio account, create a link from Moodle to your Mahara page as
indicated on the submission link. You are required to prepare your responses to the assessment tasks as a
page in your Mahara e-Portfolio. (To be submitted in Week 11)
Referencing: Your portfolio should be a synthesis of ideas from a variety of sources expressed in your
own words. A minimum of 10 references is recommended. You should use the APA referencing style.
The University has published a style guide to help students correctly reference and cite information they

Assessment Guidelines
Marking Criteria: A passing grade will be awarded to assignments adequately addressing all
assessment criteria. Higher grades require better quality and more effort. For example, a minimum is set
on the wider reading required. A student reading vastly more than this minimum will be better prepared
to discuss the issues in depth and consequently their report is likely to be of a higher quality. So before
submitting, please read through the assessment criteria very carefully. Marking guides are provided.
Feedback: Feedback will be provided by the lecturer/tutor via Mahara, and mark via Moodle, no later
than 2 weeks from the submission date.
An ePortfolio is a collection of digital files, images, videos that showcase competencies, skills,
application of knowledge and learning journey. The use of ePortfolios in various industries, disciplines
and processes is increasing world-wide, and is in some case the ‘norm’ for job applications or for
displaying educational learnings.

Assignment Questions
Part A
Q1. In relation to access to wireless network (e.g, WiFi), answer the following questions:
a. What is media access control and why is it important?
b. Give one example each of the controlled access methods and contention based media
access methods?
c. When might one access method be preferred over another in a network, and why?
d. Under what conditions do contention-based media access control techniques
outperform controlled-access techniques (i.e., have lower response time)? Explain.
[3+2+2.5+2.5=10 marks]
Q2. Four users (U1, U2, U3 and U4) are using CDMA access techniques to transmit data to their
respective receivers (U1->R1, U2->R2, U3->R3 and U4->R4). The followings are the
spreading codes and the data that each user wants to send.

StopFire is a campaign started by Monash University to predict and stop the fire in
Victorian cities. They have employed sensors in different cities of Victoria and have
collected a large amount of data. The data is so big that their techniques have failed to
provide the results on time to predict fire. They have hired us as the data analyst to
migrate their data to the NoSQL database (MongoDB). They want us to analyse their data
and provide them with results. In addition, they want us to build an application, a
complete setup from streaming to storing and analyzing the data for them using Apache
Kafka, Apache Spark Streaming and MongoDB.
What you are provided with
? Five datasets:
? hotspot_historic.csv
? climate_historic.csv
? hotspot_AQUA_streaming.csv
? hotspot_TERRA_streaming.csv
? climate_streaming.csv
? These files are available in Moodle in the Assessment section in Assignment Data
folder.
Information on Dataset
Climate data is recorded on a daily basis whereas Fire data is recorded based on the
occurrence of a fire on a particular day. Therefore, for one climate data, there can be zero
or many fire data.
The data is NOT row per weather station basis. You can simply think of it as, Station 1 was
reporting data for X number of days and then Station 2 started reporting data because
Station 1 was shut down for instance.

receive your mark and written feedback via Moodle two weeks after the due date or submission,
whichever is later.
2. INTRODUCTION
In this assignment you will model the behaviour of systems or subsystems for two of your most
complex use cases using two UML diagrams (activity diagram and system sequence diagram) and
write the extended use case description. You must also submit test plans and screens developed
using InVision.
Section 3 describes the motivation behind the design of this assignment. Section 4 provides
information on how and what to submit (note that Moodle has been setup so there is only one
submission from each group). Section 5 explains the tasks for individual and group work. You will
find the criteria for marking your submission in Section 6.
3. MOTIVATION.
The purpose of the assignment is to ensure that you know:
1. How to write extended use case texts.
2. How to model the dynamic aspect of a system using UML (activity diagram and system
sequence diagram).
3. How to develop screen prototypes to assist analysis.
4. How to develop quality test plans.The assignment addresses the following learning outcomes:
K1. Explain how models are used to assist in analysing and modifying existing business systems;
K2. Define various roles involved in the processes of system analysis;
K3. Describe techniques used to gather required information for system analysis;
K4. Explain the various stages of the system development life cycle;

ITECH2002 – Systems Modelling
Assignment 2 Specification
A1. Write integrated reports, using appropriate models, providing detailed analysis of given textual
scenarios.
4. HOW AND WHAT TO SUBMIT
• Moodle has been set up so each group submits only one document – anyone from a team can
submit.
• Submit a Word or text document which has the link to a GoogleDoc document which has the
group work and individual work and the link to the top level InVision screen. This GoogleDoc
document must be complete: if it uses LucidChart, then please include the images drawn in
LucidChart in GoogleDoc and provide the link to the LucidChart images. In other words, readers
should only need to read the GoogleDoc document without having to refer to LucidChart. We
will check the history of GoogleDoc and InVision Screens to find out how much you have
contributed to this assignment. You must share the GoogleDoc, LucidChart and InVision
Screens with your lecturer and tutor.
As a general guide to how the document should look, think about your target audience, which in
this case is another system analyst and a quality assurance (QA) team who will work with the
system. Remember that everyone is busy and overloaded with information, so please include only
the most essential information: be brief but clear. The QA team will use the test plans to develop
automated system tests. We expect the GoogleDoc document to have the following information:
1. The name of the organisation you are modelling.
2. The name and student ID of each team member and the name of the system or subsystem
modelled.
3. For each member, the extended use cases, activity diagrams, and system sequence diagrams for
two of the most complex use cases.
4. Snapshots of all screens, and a link to the top level Invision screen which links to the screen of
each member. The screen for each team member must be from one of the two use cases
selected in step 3.
5. For each member, the test plan for the use case chosen in step 4 – in other words, the test plan
must be for the same use case as for the screen design.
