Requirements Gathering

Requirements gathering is a crucial step in the process of designing a payment app. It involves gathering and documenting the needs and expectations of various stakeholders, including end-users, clients, and other relevant parties. Gathering requirements ensures that the payment app meets the desired objectives and functionalities.

As a senior engineer with a strong background in low-level design, your expertise in requirements gathering plays a vital role in shaping the success of the payment app. You will be responsible for gathering, analyzing, and documenting the requirements to ensure that the app meets the expectations of all stakeholders.

To effectively gather requirements, consider the following steps:

1. Identify Stakeholders: Identify all the stakeholders who have an interest or involvement in the payment app. This may include end-users, clients, management, developers, and regulatory bodies.

2. Conduct Interviews and Workshops: Schedule meetings and interviews with the stakeholders to understand their needs and objectives. Conduct workshops to gather insights and brainstorm ideas.

3. Document Requirements: Document the gathered requirements in a structured format. Use techniques like use cases, user stories, and functional requirements documents to capture the requirements.

6  private List<String> acceptanceCriteria;

8  public UserStory(String description, List<String> acceptanceCriteria) {
9    this.description = description;
10    this.acceptanceCriteria = acceptanceCriteria;
11  }
12
13  public String getDescription() {
14    return description;
15  }

17  public List<String> getAcceptanceCriteria() {
18    return acceptanceCriteria;
