1. Requirements Gathering: Identify and document the needs and expectations of stakeholders.
2. System Design: Create a blueprint for the system, detailing its architecture, components, and interfaces.
3. Development and Testing: Build the system according to the design, followed by rigorous testing to ensure functionality and performance.
4. Deployment and Maintenance: Launch the system for use, followed by ongoing support and updates based on user feedback and evolving requirements.
