Detailed Explanation

In the first phase, the primary goal is to elicit or gather the requirements from various stakeholders involved in the business project. This involves identifying key stakeholders such as customers who will use the online grocery ordering system, store staff who will manage the orders, the delivery team responsible for home deliveries, and administrators overseeing the system.

Next, the task includes conducting mock interviews with these stakeholders to understand their needs better. Alternatively, if mock interviews aren't possible, creating personas (fictional characters representing users or stakeholders) can help conceptualize their needs.

Finally, the creation of a stakeholder matrix, which might include the RACI (Responsible, Accountable, Consulted, Informed) framework, will visually outline the roles and responsibilities of each stakeholder in relation to the project, ensuring clarity in who does what.

In Phase 2, the focus shifts to documenting the requirements gathered from stakeholders. This starts with writing user stories, which are short descriptions of a software feature from an end-user perspective. The INVEST criteria (Independent, Negotiable, Valuable, Estimable, Small, Testable) help ensure these stories are effective.

Next, each user story requires clear acceptance criteria, which define conditions that must be met for the story to be considered complete. The Gherkin format provides a structured way to write these criteria using the 'Given-When-Then' format—helping outline initial context, action, and expected outcome clearly.

Also, it's essential to categorize requirements into business requirements (what the business needs), functional requirements (what the system must do), and non-functional requirements (system attributes like performance). Lastly, a Requirement Traceability Matrix (RTM) is created to track all requirements throughout the project lifecycle, ensuring nothing gets overlooked.

In Phase 3, the task involves modeling the system to visually represent how the online grocery ordering system will function. This begins with creating a Use Case Diagram, which illustrates the various interactions between users (actors) and the system. For instance, a use case might depict how a customer places an order.

Next, an Activity Diagram outlines the various steps a customer takes from browsing products to completing a checkout, providing a visual workflow that is easy to understand.

Finally, creating wireframes or mockups of key screens gives a blueprint of the user interface design, helping stakeholders visualize how the system will appear and function. Tools like Draw.io or Figma can assist in creating these visuals effectively.

Phase 4 is focused on optional test planning, crucial for ensuring that the system is functioning as intended before going live. The tasks in this phase include writing 3 to 5 test cases, which outline specific scenarios to verify if the system behaves correctly under various conditions. Each test case should have a unique ID and include the steps to execute, along with the expected results for validation.

These test cases should then be mapped to requirements in the Requirement Traceability Matrix (RTM) to ensure comprehensive coverage of all requirements during testing. Identifying sample defects during testing helps preempt issues in the live system, making it essential for a smooth user experience.

Detailed Explanation

In the final phase, the task shifts to summarizing the project and sharing findings with peers or mentors. This begins with creating a succinct presentation of 6 to 8 slides, ensuring that there's a clear focus on the business problem identified, the scope of solutions proposed, user stories generated, and the diagrams created in previous phases.

This presentation serves as a formal review of the work and is vital to demonstrating the deliverables generated throughout the project lifecycle. Presenting effectively can be done live or recorded, which allows for flexibility in sharing information with diverse audiences.
