08. Implementation Plan and Launch Readiness

Purpose

Turn the approved planning docs into a build sequence and a launch checklist.

Scope

• Development order.
• Milestone grouping.
• Testing plan.
• Review and approval gates.
• Launch readiness criteria.

Proposed Implementation Plan

Phase 1: Foundation

• Project setup
• Repository structure
• Environment configuration
• Database schema and migrations
• Core layout/system components

Phase 2: Public Experience

• Homepage
• Listing page
• Property detail page
• Contact page
• Content page rendering

Phase 3: Booking Core

• Availability search
• Booking form
• Price calculation
• Booking persistence
• Booking state transitions

Phase 4: Payments and Notifications

• Stripe Checkout
• Webhooks
• Confirmation emails
• Failure handling

Phase 5: Admin Console

• Property management
• Pricing and availability management
• Booking management
• Content management
• Site settings

Phase 6: Quality and Launch

• SEO validation
• Accessibility review
• Performance review
• Regression testing
• Launch readiness check

Testing Plan

• Unit tests for pricing, availability, and booking state logic.
• Integration tests for checkout and webhook handling.
• End-to-end tests for browse, book, pay, and confirm flows.
• Admin workflow tests for core management actions.

Launch Readiness Criteria

• Core customer booking flow works end to end.
• Stripe payment and webhook confirmation are reliable.
• Admin can manage live content, bookings, and availability.
• Public pages meet the agreed SEO, accessibility, and responsiveness baseline.
• No unresolved critical questions remain from the planning docs.

What Needs to Be Done

• Convert the approved planning docs into build phases.
• Set dependencies between phases.
• Define what must be tested before each stage is approved.
• Define what evidence is needed before launch.
• Define the handoff point for implementation work.
• Define what evidence each phase must produce before the next one starts.

Acceptance Criteria

• The project has a clear build order.
• The implementation phases are small enough to review one at a time.
• Testing and launch criteria are explicit.
• The next action after approval is obvious.
• The planning set is complete enough to begin implementation in controlled stages.

Dependencies

• All prior planning docs approved.

Notes

• This is the last planning doc before actual build work begins.
