Developing WhatsApp System: How You Perform Tasks In A Software House?

1. JIRA Team Responsibilities:
   • The JIRA team is responsible for setting up the project in JIRA and managing its components, such as epics, user stories, sprints, and tasks. They ensure that the project’s workflow is properly configured, and team members have the necessary access and permissions.
2. Creating Epics for WhatsApp:
   • Epics for WhatsApp could include features like messaging, media sharing, group chats, and user authentication.
3. Defining User Stories:
   • User stories could be detailed descriptions of specific functionalities within each epic, such as sending text messages, sharing photos, creating groups, and managing contacts.
4. Planning Sprints:
   • For a 6-month project, sprints could be planned on a bi-weekly or monthly basis, with each sprint focusing on completing a set of user stories or tasks.
5. System Analyst Responsibilities:
   • The system analyst gathers and analyzes requirements from stakeholders, translates them into technical specifications, and creates documentation for the development team. They use tools like Confluence for documentation and collaboration, and JIRA for requirements management.
6. Project Manager Responsibilities:
   • The project manager coordinates resources, schedules, and tasks to ensure timely project delivery. They allocate developers to specific user stories or tasks based on their skills and availability, and create tasks in JIRA for developers to work on.
7. Major Tasks in WhatsApp:
   • Some major tasks could include developing the messaging feature, implementing media sharing functionality, creating the group chat feature, and integrating user authentication.
8. Developer Responsibilities:
   • Developers write code to implement the features outlined in user stories. For example, they might create classes for managing user accounts, handling message encryption, and displaying chat interfaces. Here’s a simplified example:

// User class for managing user accounts
class User {
constructor(name, email, password) {
this.name = name;
this.email = email;
this.password = password;
}

// Methods for user authentication and profile management
authenticate() {
// Authentication logic
}

updateProfile() {
// Profile management logic
}
}

Tester Responsibilities:

• Testers verify that the application functions as expected and report any defects or issues. If using Selenium for automated testing, they could write tests to ensure that login functionality works correctly, messages are sent and received accurately, and media files are uploaded and shared without errors.

// Example Selenium test cases
public void testLogin() {
// Test login functionality
}

public void testSendMessage() {
// Test message sending functionality
}

public void testMediaUpload() {
// Test media file upload functionality
}

                    9. Deployment Team Responsibilities:

1. • The deployment team is responsible for packaging the application, configuring servers, and deploying it to production environments. For example, they might use tools like Docker for containerization, Jenkins for continuous integration, and AWS for cloud deployment. 

     10. Feedback Team Responsibilities:

     • The feedback team gathers feedback from users and stakeholders, analyzes it, and provides recommendations for improvements. For example, they might conduct user surveys, monitor app store reviews, and track user engagement metrics to identify areas for enhancement.

By effectively managing tasks and responsibilities using JIRA, each team can contribute to the successful development and deployment of the WhatsApp clone, ensuring a high-quality product that meets user needs and expectations.
