The aim of this subject is to help students develop the required skills in the planning, selection, and analysis phases of the system development life cycle. Understanding and using case diagrams, domain class diagrams, and system sequence diagrams for system development.
System Analysis is the process of an individual studying a system in order to evaluate, model, and choose a logical alternative for an information system. There are three reasons why systems analysis initiatives are started: issues, opportunities, and instructions. The systems development life cycle (SDLC) can be used to explain the process of creating systems.

Central Queensland University is one of the largest universities in Australia offering undergraduate, postgraduate, certificates, diplomas, and online courses to students at a global level.
Its main campus is in Normans Garden in Rockhampton. It also has campuses in many places in Australia including Brisbane, Bundaberg, Emerald, Macky, Melbourne, Sydney, Townsville, etc.
Express and discuss system analysis techniques.
In the analysis phase of the SDLC, use fact-finding procedures.
Using relevant methodologies, model the present system/environment.
Prepare analysis and user requirements reports to document the SDLC’s analysis phase.
This is an individual assignment. The assignment is divided into 2 parts: Part A and Part B
Part A (12.5 marks)
Part A consists of two tasks:
• Complete all online quizzes. Unlimited attempts. The highest score will be recorded as your mark. (6.25 marks)
• Complete all tutorial activities and tasks during all physical tutorial classes. Distance students will discuss and complete tutorials via online zoom classrooms. (6.25 marks)
• Note that the unit coordinator will consolidate your marks on all your online quizzes. Your
the tutor will consolidate all your tutorial work marks.
Part B (87.5 marks)
Part B requires all students to complete all Part B tasks and submit the following on Moodle:
• One (1) MS Word report containing answers for each task. The report must include unit name, unit code, student full name, student ID, campus (or distance), lecturer (or tutor) on the front page.
• One (1) MS Visio file containing the diagrams for Tasks 2, 3, 4, and 5. The diagrams must be in the same file, but on separate pages within the Visio file. A screenshot or copy-and-paste of each of the four diagrams must also be included in the MS Word report.
• For successful submissions on Moodle, include the acceptable file types as required above.
Case study – Solar Power
On the basis of the mentioned case study perform the following tasks.
Task 1: Requirements Elicitations
There are six information-gathering techniques covered in this unit. Select two most useful relevant information gathering techniques out of the six for the above scenario that would help you effectively investigate the new system requirements. You have to:
• Describe each of the two information gathering techniques in detail. Include tasks that
would be performed using the technique for the Online SolarPower System project.
• Explain the advantages and disadvantages of each technique in the context of the Online
SolarPower System project. The advantages/disadvantages are relative to all 5 other
techniques (not just the selected techniques).
Task 2: Use Case Diagram
Draw a use case diagram for the entire system within the project.
Task 3: Domain Class Diagram
Draw a domain class diagram for the entire system. You must closely follow the instructions below:
• Each class must have a primary key, e.g. customerID, productID, etc.
• Each class must have at least two or more other related attributes.
• On each association line, there must be a meaningful word reflecting the relationship in the
• Show inheritance for a superclass with TWO (2) different subclasses to handle the two credit card payment types (Visa card and Master card) as in the case scenario above.
• Indicate AT LEAST three common attributes as identified in the superclass. Indicate
appropriate different attributes as identified for the subclasses.
Task 4: Activity Diagram
Draw an activity diagram for a specific scenario that shows an online user entering his details to make an appointment for a consultation with Bob Sparks through the Online SolarPower System, and obtaining an appointment confirmation via email.
Task 5: System Sequence Diagram
Draw a system sequence diagram based on a part of the scenario, showing
“Bob Sparks hits a print button at the end of the month. Subsequently, the system prints a report for all customers with outstanding accounts, i.e. installations completed but not paid.”
