Practice Assignment

1. It’s time to reflect on what you learned about the different roles that work in software. For this activity, imagine that a company wants to add a new feature to their popular video streaming service. This feature will remind users if they haven’t finished watching a movie.

For each of the following roles, write a short (paragraph) description of the work each role does to bring the feature to end users:

Software engineer

Software architect

Product manager

Quality assurance (QA) engineer

Technical support engineer

Project manager

Software Engineer
The software engineer is responsible for writing the code that brings the new feature to life. For the reminder feature, they would develop the logic to detect when a user has paused a movie and hasn’t resumed it within a set time. They integrate this logic into the application, ensuring the reminder is triggered correctly, and that notifications are displayed in the user interface. Their work also includes writing unit tests and collaborating with the backend team to handle any necessary data storage.

Software Architect
The software architect designs the overall system structure and ensures that the new feature integrates smoothly into the existing platform. They decide how the feature will communicate with other components (e.g., databases, user profiles, and notification systems) and choose the best technologies or frameworks for scalability and performance. They also ensure that the design aligns with the platform’s long-term goals and technical standards.

Product Manager
The product manager defines the feature’s purpose, goals, and success metrics from a user and business perspective. They gather user feedback, analyze market trends, and write user stories or requirements for the development team. For this reminder feature, the product manager would explain why it’s important (e.g., increasing user engagement), determine when and how reminders should be triggered, and prioritize the feature within the product roadmap.

Quality Assurance (QA) Engineer
The QA engineer is responsible for testing the feature to ensure it works correctly and doesn’t break anything else in the app. They create test plans, perform manual and automated tests, and check for edge cases (like users switching devices mid-movie). They report bugs, verify that issues are resolved, and validate that the reminder is sent only in appropriate scenarios, helping deliver a smooth experience to users.

Technical Support Engineer
Once the feature is live, the technical support engineer helps users who encounter problems. If someone says they’re not getting reminders or getting too many, the support engineer investigates the issue using logs and tools, provides workarounds, and communicates with the development team for fixes. They also gather user feedback and identify trends in support tickets to help improve future releases.

Project Manager
The project manager oversees the entire development process, ensuring the feature is delivered on time and within scope. They coordinate across teams (development, design, QA, support), track progress, manage risks, and keep everyone aligned with timelines. They also communicate with stakeholders and ensure that the project goals are clearly understood and met at each milestone.
