Polarion® ALM is the next generation solution for Application Lifecycle Management: a fully integrated, unified platform for managing software development projects and process throughout the software life cycle. Polarion integrates requirements, tasks, change requests, process management, project planning, time management, build management, source code audits and metrics, and maturity model compliance tracking. Polarion's unique approach is built around a "single source" repository-based architecture where all artifacts in the development process are stored in a software configuration management system, namely Subversion.
