Application Lifecycle Management (ALM) refers to the process of managing the entire lifecycle of an application from initial planning and development to deployment and maintenance. It encompasses various stages, including requirements gathering, design, coding, testing, and support, ensuring that the application meets user needs and business goals. ALM involves collaboration among different teams, such as developers, project managers, and quality assurance professionals, to streamline workflows and improve efficiency. By using tools and methodologies, ALM helps organizations track progress, manage changes, and ensure the quality of applications throughout their lifespan.
