What does the deployment phase refer to in app development?

The deployment phase in app development signifies the process where the finished product is made available to users. This phase occurs after extensive testing and debugging efforts, ensuring that the app is functioning correctly. During deployment, the application is distributed to users through various channels, such as app stores, websites, or internal systems, depending on the target audience. This can include preparing necessary documentation, marketing materials, and support services to enhance accessibility and success upon release.

Understanding the deployment phase is crucial as it marks the transition from development to real-world use, where feedback from actual users can lead to further improvements and future updates. The other options, such as initial code testing, user experience design, and code refactoring, represent different stages or aspects of the development lifecycle that take place before deployment.
