LieberLieber Software and Siemens present their Polarion ALM - Enterprise Architect integration. This state-of-the-art integration is based on the latest technology and brings important updates for users of both systems. Siemens, developer of the market-leading Polarion Application Lifecycle Management (ALM) solution and LieberLieber Software, specialist for the widely used modelling platform Sparx Systems Enterprise Architect, establish with this step their partnership around Model Based Systems Engineering (MBSE). The now published integration enables users to synchronise requirements, model attributes as well as links and references between Polarion ALM and Enterprise Architect. This makes it even easier to navigate back and forth between the two platforms while development data is automatically synchronised. Overall, the new Polarion ALM - Enterprise Architect integration closes the loop between requirements and model artefacts in an MBSE environment. For end-product developers with complex systems engineering processes, the software integration provides traceability, transparency and increased speed of delivery. References between requirements are available in Enterprise Architect, while connections between requirements and architecture are represented in Polarion. This allows users to easily monitor and manage complex product delivery processes, even in regulated industries.
