+# BMS AI Assistant: System Documentation
+## 1. Executive Summary
+The BMS AI Assistant is an enterprise-grade conversational interface designed to optimize supply chain operations. By leveraging local AI inference and deterministic forecasting models, the system provides instant access to critical business data—including demand forecasts, inventory levels, and supplier information—without relying on external cloud APIs.
+## 2. System Architecture
+### 2.1 High-Level Design
+The system operates on a micro-service architecture containerized within Docker.
+*   **Presentation Layer:** HTML5/JavaScript frontend served via FastAPI.
+*   **Application Layer:** Python-based backend handling intent parsing and business logic.
+*   **Data Layer:** In-memory CSV data structures for high-performance retrieval.
+*   **Intelligence Layer:** Hybrid engine combining ARIMA (Statistical) and TinyLlama (Generative AI).
+### 2.2 Process Flow
+1.  **Input:** User submits natural language query.
+2.  **Parsing:** Regex engine extracts Intent (e.g., "Forecast") and Entities (e.g., "BMS0015").
+3.  **Routing:** Request is directed to the appropriate module (Forecasting, Inventory, etc.).
+4.  **Execution:** Module performs computation or data lookup.
+5.  **Response:** Results are formatted into JSON and rendered by the frontend.
+## 3. Technical Specifications
+| Component | Technology | Specification |
+| :--- | :--- | :--- |
+| **Backend** | Python / FastAPI | v0.104+, Async I/O |
+| **Server** | Uvicorn | ASGI Standard |
+| **Forecasting** | Statsmodels | ARIMA(1,1,1) |
+| **LLM** | TinyLlama | 1.1B Parameters, Quantized |
+| **Frontend** | HTML/JS | Zero-dependency, Vanilla JS |
+| **Deployment** | Docker | Debian-based Python Slim Image |
+## 4. Key Capabilities
+### Demand Forecasting
+*   **Methodology:** Time-series analysis using historical sales data.
+*   **Output:** 30-day forward-looking demand schedule.
+*   **Accuracy:** Optimized via ARIMA parameter tuning.
+### Inventory Management
+*   **Scope:** Multi-location stock tracking.
+*   **Features:** Real-time "On Hand" vs "Allocated" visibility.
+### Reporting
+*   **Format:** PDF (Generated on-demand).
+*   **Content:** Chat transcripts, forecast tables, and system alerts.

+*   **Language:** Python 3.10
+*   **Framework:** FastAPI + Uvicorn
+*   **AI Model:** TinyLlama 1.1B (Local Inference)
+*   **Deployment:** Docker Container
+---
+# Slide 6: Process Flow
+**Steps:**
+1.  **User Input:** Natural language query.
+2.  **Intent Recognition:** Pattern matching algorithm.
+3.  **Data Retrieval:** SQL/CSV lookup or Model Inference.
+4.  **Response Generation:** JSON formatting and UI rendering.
+---
+# Slide 7: Future Roadmap
+**Next Steps:**
+*   Integration with live ERP database (SQL).
+*   Advanced multi-variate forecasting models.
+*   User authentication and role-based access control.

+# Team Announcement Email Drafts
+Here are three versions of the email you can send to your team. Choose the one that best fits your team's culture.
+---
+## Option 1: The "Vibe Coding" Approach (Recommended)
+*Best for highlighting the innovative/experimental nature of the project.*
+**Subject:** POC: BMS AI Assistant - Built with Gemini & Open Source Tools
+Hi Team,
+I did some "vibe coding" this weekend using Gemini to build a Proof of Concept (POC) for our supply chain operations. I wanted to see how quickly we could spin up a functional AI assistant using 100% open-source tools without any licensing costs.
+**What it is:**
+A chatbot that can forecast demand, check inventory, and answer supplier questions in real-time.
+**The Tech Stack:**
+It’s running entirely on open-source technology:
+*   **Backend:** FastAPI (Python)
+*   **AI Model:** TinyLlama (Local inference, no API costs)
+*   **Forecasting:** ARIMA (Statistical modeling)
+*   **Hosting:** Hugging Face Spaces (Dockerized)
+**Try it out here:**
+👉 **[Link to BMS AI Assistant](https://huggingface.co/spaces/bmsuser/BMS-AI-BOT)**
+*(Note: It might take a minute to wake up if it's been idle)*
+**Documentation:**
+I've attached the **Technical Specification** and **Process Flow** documents if you want to dive into the architecture.
+Please play around with it and let me know what you think! Since this is a POC, I'm looking for suggestions on features or use cases we might have missed.
+Best,
+[Your Name]
+---
+## Option 2: Professional & Direct
+*Best for a formal corporate environment.*
+**Subject:** For Review: BMS AI Assistant Prototype (Open Source POC)
+Team,
+I have deployed a prototype of the **BMS AI Assistant**, a conversational tool designed to streamline our access to demand and inventory data.
+This POC was built to demonstrate the feasibility of using purely open-source, cost-effective technologies for enterprise AI. It leverages local LLMs and statistical forecasting models to provide instant answers without external API dependencies.
+**Access the Application:**
+https://huggingface.co/spaces/bmsuser/BMS-AI-BOT
+**Key Features to Test:**
+*   **Demand Forecasting:** Ask for forecasts on specific items (e.g., "Forecast for BMS0015").
+*   **Inventory Checks:** Query real-time stock levels.
+*   **Supplier Info:** Retrieve vendor details.
+I have attached the full **Technical Specifications** for your review. Please test the system and provide your feedback on its potential utility for our workflows.
+Regards,
+[Your Name]
+---
+## Option 3: Short & Casual
+*Best for Slack/Teams or quick updates.*
+**Subject:** Check this out: AI Bot for BMS (POC)
+Hey everyone,
+I hacked together a quick POC for an AI Assistant using Gemini and some open-source tools (FastAPI, Llama, etc.). It’s actually working pretty well for forecasting and inventory checks.
+**Live Demo:** https://huggingface.co/spaces/bmsuser/BMS-AI-BOT
+I've attached the specs if you're curious about how it works under the hood.
+Give it a spin and let me know if this vibe works for us!
+Cheers,
+[Your Name]
