Break Down Epics into Developer-Ready User Stories

USER Input: Epic: “Users should be able to update their shipping address after placing an order—as long as it hasn’t shipped yet.” Product: Ecommerce dashboard Target user: End customer Needs: MVP scope suggestion AI Output: 🧩 Ticket 1 Title: Add "Edit Shipping Address" button to order overview User Story: As a customer, I want to update my shipping address after placing an order, so I can fix mistakes without cancelling. Acceptance Criteria: Button is only visible if order status is “Processing” Clicking opens an editable address form UX copy explains when updates are allowed 🧩 Ticket 2 Title: Build shipping address form with validation User Story: As a customer, I want to edit my shipping address in a simple form, so I can correct typos or update recipients. Acceptance Criteria: Form is prefilled with current address Validates fields (postal code, city, street, country) Sends update request to backend on submit 🧩 Ticket 3 Title: Create backend endpoint to update shipping address User Story: As a system, I need a secure endpoint to update a shipping address, so that frontend changes are reflected in the database. Acceptance Criteria: PUT /orders/{id}/shipping-address Allowed only when status = “Processing” Change is logged with timestamp and user ID 🧩 Ticket 4 Title: Send confirmation email when address is updated User Story: As a customer, I want a confirmation email when I update my shipping address, so I know the change was successful. Acceptance Criteria: Email sent on successful update Includes new address Follows transactional template 🧩 Ticket 5 Title: Block address updates after shipping User Story: As a system, I want to prevent shipping address changes once an order is marked as shipped, so that fulfillment isn’t disrupted. Acceptance Criteria: Button hidden or disabled when status = “Shipped” API call rejected if attempted post-shipping 🗂 Suggested Sprint Order: Backend endpoint Address form UI logic for button Confirmation email Locking logic ✅ MVP Scope Suggestion: Include backend + address form + lock logic. Button placement and email confirmation can be added in a follow-up sprint. ⚠️ Risks & Open Questions: Should updated addresses trigger shipping rate recalculation? How soon after purchase should edits be allowed? (e.g., within 2 hours?)
