  5. Non FunctionalRequirements Bugs Dev Team Tasks UseCase Business Analyst Project Manager Test Production Errors Operations Application Lifecycle ManagementWhat is it & why is it useful? Application lifecycle management (ALM) regards the process of delivering software as a continuously repeating cycle of inter-related steps: definition, design, development, testing, deployment and management. Change Requests “ALM solutions are integrated tool sets that support and unite the following lifecycle activities: requirements management, design and modeling, development, software configuration management (SCM), and testing.”
