# 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 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.
