Milestone 1: Discovery and Planning​

  • Goal: Define project requirements, key objectives, and architecture.
  • Details:
    • Conduct research on user needs, LLM capabilities, and expected system load.
    • Define project scope, including the primary features and user stories.
    • Outline initial system architecture (frontend, backend, cache, databases).
    • Set up project repository, CI/CD pipelines, and preliminary development environment.
  • Deliverables: Requirements document, architecture diagram, project timeline, and initial codebase setup.

Milestone 2: Core Infrastructure Setup​

  • Goal: Establish core infrastructure, including storage, databases, and background processing.
  • Details:
    • Set up and configure Document Storage (AWS S3 or MinIO), Vector Database (Qdrant), and Relational Database (SQL Server).
    • Configure the background task queue (Celery on AWS Step Functions or similar) for asynchronous tasks like embedding documents.
    • Establish serverless or managed services for storage and databases to reduce costs and improve scalability.
  • Deliverables: Functional infrastructure with integration tests confirming connectivity and data storage.

Milestone 3: Prototype Completion​

  • Goal: Develop a functional prototype with basic LLM and embedding model integration.
  • Details:
    • Integrate the LLM API (e.g., OpenAI API) and embedding model (GPT or PhoBERT) for basic query processing.
    • Build a simple frontend UI (NextJS) for users to submit queries and receive responses.
    • Implement a basic API server (FastAPI on AWS Lambda) with reverse proxy (Nginx).
    • Test end-to-end flow from user input to LLM response and back.
  • Deliverables: Basic functional prototype enabling user queries and AI-generated responses.

Milestone 4: Core Features Developed​

  • Goal: Implement essential features like document processing, caching, and vector search.
  • Details:
    • Implement background tasks for document embedding and storage in the Vector Database.
    • Add caching (Redis) for frequently accessed queries to improve response times.
    • Build vector-based search functionality for finding similar documents based on embeddings.
    • Refine UI and backend to support these features with scalability in mind.
  • Deliverables: Feature-complete application with document embedding, caching, and search.

Milestone 5: Alpha Release (Internal Testing)​

  • Goal: Launch an internal version for testing core functionalities and performance.
  • Details:
    • Deploy to a test environment with restricted access for internal team members.
    • Conduct usability testing for UI, API reliability, and system stability.
    • Run initial performance tests to check if response times and throughput meet expectations.
    • Collect internal feedback to refine UX and resolve major issues.
  • Deliverables: Stable alpha version with feedback from internal testing and an updated backlog.

Milestone 6: Beta Release (Limited User Testing)​

  • Goal: Release a beta version for a limited audience to gather real user feedback.
  • Details:
    • Deploy to a production-like environment with limited access for select users.
    • Implement logging and monitoring to capture usage patterns, errors, and bottlenecks.
    • Integrate a feedback system to gather insights on user experience and response accuracy.
  • Deliverables: Beta version with logging and analytics, and documented user feedback.

Milestone 7: Performance and Security Optimization​

  • Goal: Optimize the system for speed, efficiency, and security.
  • Details:
    • Optimize caching for frequently accessed responses.
    • Review and optimize vector database queries for faster results.
    • Conduct a security audit focused on data protection, authentication, and permissions.
    • Run load testing to confirm system scalability.
  • Deliverables: Performance-optimized, secure application ready for a wider release, with testing reports.

Milestone 8: Public Launch Preparation​

  • Goal: Finalize all details for a successful public release.
  • Details:
    • Complete final testing, including UAT (User Acceptance Testing), to ensure functional readiness.
    • Finalize documentation for users and developers, including API docs and setup guides.
    • Prepare marketing and user onboarding materials, if needed.
    • Establish support channels for post-launch user queries.
  • Deliverables: Launch-ready product, comprehensive documentation, and user onboarding resources.

Milestone 9: Version 1.0 - Public Launch​

  • Goal: Release the application to all intended users.
  • Details:
    • Officially launch the application with monitoring for critical issues.
    • Monitor user activity and metrics for the first 24-48 hours to ensure stability.
    • Provide support for major issues with a rapid response plan.
  • Deliverables: Full public release with active user support and monitoring.

Milestone 10: Post-Launch Improvements (Version 1.1)​

  • Goal: Address post-launch feedback and add minor improvements.
  • Details:
    • Collect and analyze public feedback to identify improvement areas.
    • Resolve post-launch issues or bugs based on user reports and monitoring.
    • Implement minor feature enhancements or optimizations.
  • Deliverables: Improved version with bug fixes, optimizations, and minor enhancements.

Milestone 11: Scaling and Maintenance (Ongoing)​

  • Goal: Ensure the application is scalable and well-maintained.
  • Details:
    • Review performance under varying loads to identify scaling needs.
    • Set up maintenance plans for databases, storage, and serverless resources to optimize costs.
    • Prioritize future feature requests for competitive advantage.
  • Deliverables: Scalable, well-maintained application with a roadmap for future updates.

This plan provides a structured path from initial development to launch and ongoing maintenance, helping ensure that each stage is well-prepared and aligned with the project’s goals.
