Coit11226 Systems Analysis Answers | Assessment Answer

Answer:

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 assuring that the needs and requirements of the stakeholders are fulfilled. The process of interview includes meeting with the stakeholder and asking the questions related to their expectations from the system.

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.

Advantages and Disadvantages

Advantages	Disadvantages
Interview
This is far better technique for identifying the needs and requirements of the end user	Time consuming
Deeper level of engagement with the end user	Bouncing ideas
Much easier to make the arrangement of the session to communicate with an individual rather than communicating with o group.
It allows to gain better ‘buy in’ rom the stakeholders
Offers better and effective support in the next stages of the project
Questionnaires
Faster	Consumes time in designing
Different stakeholders can be targeted	A good number of participant necessary
Saves time for further activities	One way conversation

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

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.
