Your question is Software Development Lifecycle. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the software development lifecycle and your experience with it.
Describe the lifecycle phases you have used, how work moves from requirements through design, development, testing, deployment, and maintenance, and how your responsibilities changed across those phases. Use one real project example and explain how your team managed quality, feedback, risks, and delivery.
