+# Implementation Plan with Timeline
+
+This document outlines a proposed implementation plan with timeline for the Drinks Inventory System.
+
+## Phase 1: Project Setup and Foundation (Week 1)
+
+### Week 1: Setup and Basic Structure
+- **Days 1-2: Project Setup**
+  - Set up database connection and configuration
+  - Create database schema migration scripts
+  - Configure dependency injection container
+  - Set up Twig template engine
+  - Create base layout template
+  - Set up error handling and logging
+
+- **Days 3-5: Entity and Repository Classes**
+  - Create all entity classes (DrinkType, InventoryRecord, Order, OrderItem, SystemConfig)
+  - Create all repository classes with basic CRUD operations
+  - Set up database schema and initial migrations
+  - Write unit tests for entities and repositories
+
+## Phase 2: Core Features Implementation (Weeks 2-3)
+
+### Week 2: Drink Type and Inventory Management
+- **Days 1-2: Service Layer**
+  - Implement DrinkTypeService
+  - Implement InventoryService
+  - Write unit tests for services
+
+- **Days 3-5: Controllers and Templates**
+  - Implement DrinkTypeController with routes
+  - Implement InventoryController with routes
+  - Create templates for drink type management
+  - Create templates for inventory management
+  - Write feature tests for controllers
+
+### Week 3: Order Management
+- **Days 1-3: Order Management Implementation**
+  - Implement OrderService with automatic order calculation
+  - Implement OrderController with routes
+  - Create templates for order management
+  - Write unit and feature tests
+
+- **Days 4-5: Dashboard Implementation**
+  - Implement DashboardController
+  - Create dashboard template with overview of stock levels
+  - Implement low stock alerts
+  - Create quick update form for inventory
+
+## Phase 3: Advanced Features and Refinement (Weeks 4-5)
+
+### Week 4: Adaptive Stock Level and Settings
+- **Days 1-3: Adaptive Stock Level Adjustment**
+  - Implement StockAdjustmentService
+  - Implement consumption pattern analysis
+  - Implement automatic stock level adjustment
+  - Write unit tests for stock adjustment
+
+- **Days 4-5: Settings Implementation**
+  - Implement ConfigurationService
+  - Implement SettingsController
+  - Create settings templates
+  - Write tests for configuration
+
+### Week 5: UI Enhancements and Refinement
+- **Days 1-3: UI Enhancements**
+  - Implement responsive design
+  - Add color coding for stock levels
+  - Implement mobile-friendly interface
+  - Add form validation and error messages
+  - Implement loading indicators
+
+- **Days 4-5: Testing and Bug Fixes**
+  - Conduct comprehensive testing
+  - Fix identified bugs
+  - Optimize performance
+  - Refine user experience
+
+## Phase 4: Documentation and Deployment (Week 6)
+
+### Week 6: Documentation and Deployment
+- **Days 1-3: Documentation**
+  - Create user documentation
+  - Document API endpoints
+  - Document configuration options
+  - Update technical documentation
+
+- **Days 4-5: Deployment**
+  - Set up production environment
+  - Configure database for production
+  - Set up backup system
+  - Configure error logging for production
+  - Perform final testing in production environment
+
+## Development Approach
+
+### Iterative Development
+- Each feature will be developed following these steps:
+  1. Implement entity and repository classes
+  2. Implement service layer with business logic
+  3. Implement controller with routes
+  4. Create templates and UI components
+  5. Write tests
+  6. Review and refine
+
+### Testing Strategy
+- Unit tests for all entity, repository, and service classes
+- Feature tests for controllers and UI flows
+- Integration tests for database operations
+- Manual testing for UI and user experience
+
+### Code Quality Assurance
+- Follow PSR coding standards
+- Use static analysis tools (PHPStan, Rector)
+- Conduct code reviews
+- Maintain high test coverage
+
+## Risk Management
+
+### Potential Risks and Mitigation Strategies
+- **Scope Creep**: Strictly adhere to the defined requirements and manage change requests
+- **Technical Challenges**: Allocate additional time for complex features
+- **Integration Issues**: Implement comprehensive integration testing
+- **Performance Issues**: Conduct performance testing early and optimize as needed
+
+## Conclusion
+
+This implementation plan provides a structured approach to developing the Drinks Inventory System over a 6-week period. The phased approach allows for incremental development and testing, ensuring that each component is properly implemented and integrated before moving on to the next phase.
