Inventory Management System Development Plan

Project Overview

Vision and Objectives

To develop a streamlined, efficient inventory management system specifically tailored for a beverage warehouse. The system will facilitate real-time inventory tracking, order management, expiry date monitoring, and demand forecasting to optimize stock levels, reduce waste, and improve operational efficiency.

Stakeholders

  • Warehouse Managers
  • Inventory Clerks
  • Development Team (Front-end, Back-end, QA)
  • Suppliers

System Requirements

Key Features

  • Stock Tracking and Management: Real-time monitoring of beverage stock levels, with detailed tracking of types, brands, sizes, and storage locations.
  • Batch and Expiry Date Management: Tracking of batch numbers and expiry dates to ensure efficient stock rotation and minimize waste.
  • Order Processing: Simplified management of purchase and sales orders, including returns, to maintain accurate stock levels.
  • Barcode Scanning: Integration with barcode technology for efficient inventory handling and stocktakes.
  • Demand Forecasting: Utilization of historical sales data to predict future demand and inform stock replenishment.
  • Supplier Management: Management of supplier information and order history to streamline procurement processes.
  • Automated Reordering: Automatic notifications or purchase orders triggered by low stock levels.
  • Reporting and Analytics: Generation of reports on stock levels, sales performance, and order history for strategic planning.
  • Multi-Location Support: Capability to manage inventory across multiple warehouse locations or storage areas.
  • User-Friendly Interface: Development of an intuitive and easy-to-navigate interface for all user interactions with the system.

Technical Requirements

  • Front-end Development: Utilize Flutter for developing a cross-platform application accessible via mobile and web.
  • Back-end Development: Use Django for creating a robust, scalable back-end capable of handling inventory data management, API requests, and business logic.
  • Database: PostgreSQL for production due to its robustness and compatibility with Django; SQLite for development and testing.
  • Authentication: Implement secure authentication mechanisms, potentially incorporating JWT for secure communication between front-end and back-end.

Development Plan

Agile Methodology

  • Utilize Agile practices, breaking down the project into 2-week sprints.
  • Employ Jira for sprint planning, task management, and progress tracking.
  • Use Confluence for documenting project details, decisions, architecture, and user manuals.

Design Phase

  • System Architecture: Define the architecture, including the API structure between Flutter and Django.
  • Database Schema: Design the schema focusing on inventory management needs.
  • UI/UX Design: Develop mockups for the application, prioritizing usability and efficiency.

Development Setup

  • Environment Setup: Configure development environments for both Flutter and Django.
  • Project Initialization: Set up the initial projects in Flutter for the front-end and Django for the back-end.

Implementation and Testing

  • Sprint Execution: Develop features according to priority, focusing on delivering functional increments each sprint.
  • Testing: Implement unit, integration, and user acceptance testing to ensure reliability and usability.

Deployment and Maintenance

  • CI/CD Setup: Establish pipelines for continuous integration and deployment.
  • Deployment: Choose a cloud provider and set up the production environment.
  • Maintenance: Plan for ongoing support, bug fixes, and feature enhancements.

Training and Documentation

  • Provide comprehensive documentation for system users and maintainers.
  • Conduct training sessions for end-users to ensure successful adoption.

Additional Technologies and Tools

  • Django REST Framework for API development.
  • Celery for background task processing.
  • Docker for containerization.
  • Nginx/Gunicorn for serving the Django application.
  • Git for version control.
  • GitHub Actions/GitLab CI for CI/CD.
  • Swagger/Redoc for API documentation.

Conclusion

This document outlines a structured approach for developing an inventory management system tailored to the needs of a beverage warehouse. By leveraging Flutter and Django, and employing Agile methodologies, we aim to deliver a user-friendly, efficient, and scalable solution that meets the client's operational requirements and business objectives.
