Requirements Case Study
Outcomes addressed in this activity:
Identify technological needs of a business.
Describe system requirements.
IT460-2: Analyze user needs to develop a requirements document including a feasibility study.
Purpose: Hands-on Case Study to Describe System Requirements
Analyze the Amazon.com website. Create a list of functional and nonfunctional business requirements that the system meets. Functional requirements begin to define how the system will support the user in completing a task. Nonfunctional requirements are the quality attributes, design, and implementation constraints, and external interfaces which a product must have.
For functional requirements identify at least three requirements and provide at least 3 examples for that requirement. You will need to label each function. Use the outline format so that each requirement is clearly identified with unique numbers.
At least one functional requirement (with three examples) must be related to process-oriented concerns (a process the system must perform or do)
At least one functional requirement (with three examples) must be related to information-oriented requirements (information the system must contain).
A third functional requirement (with at least three examples) of your choice. You need to identify what this functional requirement relates to.
A fourth functional requirement (with at least three examples) of your choice. You need to identify what this functional requirement relates to.
For nonfunctional requirements provide examples for each of the four categories:
Operational (at least two examples)
Performance (at least two examples)
Security (at least one example)
Cultural/Political (at least one example)
Documenting your work and evidence is important for systems analysis. Include at least one screenshot of your visit to Amazon. Write a short paragraph (at least 50 words) explaining how you arrived at your functionality requirements from your exploration of the site. Note how you determined the functional requirements.
In the textbook, Systems Analysis and Design, Fifth Edition, the following table describes Functional and Nonfunctional Requirements:
