Deploying and Demonstrating the Application involves the process of making a developed application available in a live or test environment and showcasing its functionality to users or stakeholders. Deployment includes packaging the application, configuring environments, and ensuring all dependencies and services are properly set up. It also involves verifying performance, security, and stability before release. Demonstration focuses on presenting key features, workflows, and user interactions to highlight application capabilities. This process helps validate requirements and gather feedback for improvements. It is a critical step in the software development lifecycle to ensure successful delivery and adoption of the application.
