COIT11226 Systems Analysis

There are six information gathering techniques covered in this unit. Select two most useful relevant information gathering techniques for the above scenario that 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 ordering system project.
• Explain the advantages and disadvantages of each technique in the context of the online ordering system project. The advantages/disadvantages are relative to all 5 other techniques (not just the selected techniques).

What to include in your report for this task?

1. Description of two techniques
2. Explanation of advantages/disadvantages of selected technique 1
3. Explanation of advantages/disadvantages of selected technique 2

Draw a use case diagram for the system within the project. What to include in your report for this task?

1. A screenshot or copy-and-paste of the diagram. You MUST also submit the original MS Visio file containing the diagram.
2. Succinct explanations and supporting assumptions for your UCD.

Information Gathering Techniques

Following are the techniques those could be utilized for the information gathering techniques:

Interview: Interviewing the stakeholders involved or associated with the system allows the system analyst to gather the information related to the needs and requirements of the stakeholders. This information could be utilized for proposing the system that can be helpful in assurin

Questionnaire: It can be expressed as a tool for the survey that allows the system analyst to prepare a set of questions regarding the specification of the system through targeting the group of stakeholders. It consists of many questions those could be open ended, close ended, or optional regarding the point of view for a single question. The questionnaire for different stakeholder groups should consist of questions related to their background and interest. The answers could be used for finalizing the overall result in the form of the charts or pies that can present the visual representation of the stakeholders thought regarding the proposed system.

Explanations and Assumptions

There are three important use cases as expressed in the above figure including Register, Carpet selection and Payment those include other sub use case as an extension of the use case or options included in the use case. Log In use case is associated with the registration and thus, the user can only log in if he or she has registers in the system. Carpet selection use case include three sub cases for the selection of sizes of the carpet that has been further extended to selection of the

Explanations and Assumptions

The above class diagram is a composition of the inheritance, aggregation and association with the enlisted entities. The above class diagram presents the visual representation of the database management system for the LPC for selling and purchasing carpets.

Explanation

The initial state of the system will allow the user to register in the system and create unique id to access the system. The user will be allowed to search for the carpet after registering and logging into the system. Thereafter, the user will be asked to select the size of the carpet and move to checkout point. This will be a loop allowing the customer to re-enter the loop and make another transaction if he or she wants to. Thereafter the payment mode will be selected and the customer will make the payment.
