From 13 – 14 May 2025, the Prostep ivip Symposium took place at the Berlin Congress Centre. LieberLieber shared a stand there with its sister company Sparx Systems Europe and was delighted by the great interest in LemonTree.Connect and topics such as digital twins and SysML v2.
In the run-up to the conference, Prostep ivip announced that the Aerospace and Defense PLM Action Group (AD PAG) – an association of companies from the aerospace and defence industry – was supporting its initiative for a Code of PLM Openness (CPO). A recent industry study conducted by CIMdata on behalf of the AD PAG revealed that the lack of openness in IT systems is a major obstacle to the implementation of model-based systems engineering (MBSE) and digital twins. Dr Konrad Wieland, CEO of LieberLieber, comments: ‘We are delighted with this initiative by Prostep ivip, as MBSE is now being recognised by more and more industries as an important strategy for overcoming the growing complexity of products. The European Space Agency (ESA), for example, is focusing on MBSE in its developments in order to be able to work faster and more cost-effectively. At our MBSE Summit 2025 event, we have therefore also placed a focus on aerospace and will be discussing key topics such as digital twins and SysML v2.’

ALM-integrations with LemonTree.Connect
On the very first day, interested parties visited the LieberLieber exhibition stand as part of a guided tour and asked questions about our areas of work. Our ALM integrations with LemonTree.Connect, the modern link between ALM and Enterprise Architect, always attract particular interest at this event. The integrations currently exist for Polarion (Siemens), Codebeamer (PTC) and Jama Connect (Jama). They synchronise requirements, model attributes, links and references between ALM tools and Enterprise Architect. This technology, combined with LemonTree for diff and merge, enables version control, comparison and merging of architecture models. It also establishes traceability between imported requirements from the ALM tool and architectural elements in Enterprise Architect. More information about LemonTree.Connect can be found in a separate LieberLieber Folder.
MATISSE and SysML v2
In the European research project MATISSE, LieberLieber is currently working on the model-based development of digital twins for the early verification and validation of industrial systems. At the same time, we are also active in working groups on the topic of SysML v2. Konrad Wieland: ‘This further development of SysML will open up new possibilities, particularly in the area of MBSE, which we are already discussing in detail with customers and interested parties in order to be able to adapt existing development strategies as quickly as possible.’ In the workshop ‘What doese SysML v2 mean for the MBSE industry’ on 14 May, Daniel Siegl and other experts presented the latest developments relating to SysML v2.
