COIT20248 Information Systems Analysis & Design

Assignment 2 is a group assignment (each group consists of 3 to 4 students). Your course knowledge gained about how to model the systems requirements will be assessed through the tasks in this assignment. You also need to produce a website design. This assignment has the following tasks, with reference to the case study NQ Air Conditioning (NQAC) provided to you on Moodle:

Introduction
Identify all critical use cases.
Draw the context diagram.
Draw the next level DFD immediately below the context diagram, depicting all the business processes.
Draw the entity-relationship diagram (ERD) showing all required entities and their relationships.
Develop a website UI design (showing all the webpages).
Provide at least 4 complete test cases for testing the application.
Provide Installation strategy specific for NQAC.
Summary of and conclusion

Since the report mostly involves diagrams, tables and sample screens, the report has no word limit (however, I prefer a concise rather than wordy report). Note that tasks 2 to 8 above refer to the design of the new system, not the existing system. If these tasks are based on some assumptions you have made, state these assumptions clearly in the report to support your design.

In addition to the report, your group also needs to produce a video presentation (about 5 to 10 minutes; marks will be deducted if the video is longer than 10 minutes) to explain your website design (item 8 above). For group presentations, nominate two members to participate in the presentation.

Case Study - NQ Air Conditioning E-Commerce

NQ Air Conditioning Installers (NQAC) undertake installations of ducted air conditioning systems in their customers' buildings. Each of these installations is carried out by a technician and it takes generally more than a day to complete an installation.

NQAC has approached you to design an E-Commerce Application (hereafter called as system) to allow potential customers choose and order air-conditioning packages online, also an administration section of the E-Commerce web site to allow NQAC staff to manage and maintain the records of Air conditioning installations.

The system should have 2 security access levels
1) no login, free access for public to make an order
2) secured logging for staff and technicians to manage and maintain customer orders

Just like any other e-commerce NQAC web site allows customers to:
• choose a predesigned ducted air conditioning package from a catalogue
• provide design details such as number of zones and outlets
• provide customer information such as name phone address etc
• provide installation details such as preferred start date

In an event of an order made by a customer, an email is sent to the relevant admin staff, and the staff will be able to:
• Login to the system
• Validate the customer information (for example call the customer to make sure is not a fake order)
• If the order is valid assign a date and a technician to inspect the building
• Can see all the ongoing and finished jobs and
• send an invoice to a customer if the job is flagged as finished

A technician can loin to the system to:
• see the jobs assigned to them
• take a job and do an inspection
• make a report about the cost of the installation
• confirm the start and the end date for the installation job
• make and attach comments about an ongoing installation
• confirm a job is finished
