LieberLieber Success Stories
LieberLieber: MBSE for the aeorspace industry
The space industry is at the beginning of a new era in digital engineering and information management. The ESA (European Space Agency), for example, is relying entirely on Model Based Systems Engineering (MBSE). Against this backdrop, Beyond Gravity Austria recently began modelling and is being supported by LieberLieber.
LieberLieber: Modelling for cancer proton therapy
IBA is the world leader in particle accelerator technology. Within IBA R&D, a small group of experts has been using Enterprise Architect for over 15 years for this purpose. Now the use of modelling is being significantly expanded with LemonTree, among others, as the company has come to appreciate the advantages of Model Based Systems Engineering (MBSE).
LieberLieber: Agriculture is going digital
In 2021, the German agricultural engineering family group CLAAS generated
sales of 4.8 billion euros with around 11,900 employees. Within the group,
CLAAS E-Systems is responsible for the development of electrical and
electronic systems for agricultural machinery. Enterprise Architect has been
used there for many years as the standard editor for modelling SysML and
UML models. Now, LemonTree has also been added to the engineering tool
chain. For the realisation of future digitisation projects, powerful tools are
thus available to apply the necessary development processes and methods
in a targeted and efficient manner.
LieberLieber: LemonTree is very popular in higher education
Vince Molnár is an assistant professor at the Budapest University of Technology and Economics, where he teaches MBSE with a groundbreaking paradigm shift towards automated quality gates and reviewing pull requests rather than grading submissions. Last semester he used Enterprise Architect, GitHub with SmartGit and LemonTree with LemonTree.Automation with great success for the first time in a course with over 80 students.
SparxSystems CE and LieberLieber proudly present: The model-based healthcare system
In the Whitepaper “Model-driven digital health”, Oliver Matthias Kipf, Solution Lead at BIX (a Boehringer Ingelheim company), presents the many opportunities that a healthcare system whose development is based on a model-based approach can offer. SparxSystems Central Europe and LieberLieber welcome this initiative and support the vision outlined in the Whitepaper.
LieberLieber: Festo uses LemonTree.Connect
With more than 20,000 employees, Festo serves about 300,000 industrial customers in 176 countries. In the “Embedded Software Platform” project, LemonTree.Connect codeBeamer has recently been used in addition to Enterprise Architect and LemonTree. This bridges the gap between requirements management and the modelling world and makes the exchange of data much easier and faster.
LieberLieber: Modelling brings more safety
The EU research project VALU3S aims to reduce the development effort of automated systems with regard to safety, cyber security and data protection requirements (Safety & Security). For this purpose, 41 partners from 10 countries worked closely together over the past three years. LieberLieber was able to convince all partners of the advantages of modelling with Enterprise Architect and was significantly involved in the development of a new modelling language.
LemonTree as a Swiss pocket knife for models
For about 20 years, the volunteer team of the open source project railML has been working on the standardisation and simplification of data exchange in the railway sector. In 2022, the work carried out is to be officially recognised and thus become binding by being recorded as ISO/TS 4398:2022 „RailDax“. The team has been using Enterprise Architect for several years, and recently also LemonTree, which is already referred to there as the Swiss pocket knife for models.
LieberLieber: Webasto moves into the future with MBSE
The Webasto Group, a family-owned German automotive supplier, generated 3.7 billion euros in sales in 2021 with around 15,700 employees, making it one of the 100 largest suppliers worldwide. The group has been implementing MBSE for about two years and relies on Enterprise Architect, LemonTree and the active support of LieberLieber.
LemonTree 3.0
When LieberLieber launched its product LemonTree four and a half years ago, its success story was not yet foreseeable. However, as the trends in software and system development continued to intensify, LemonTree 3.0 now opens up completely new possibilities for product line development, use in the supply chain and team-based modelling.
NATO relies on Enterprise Architecture
With the aim of modernising its business and IT landscape, NATO is relying on the recently introduced NAFv4 framework. The german Bundeswehr and the Swiss Army have chosen Enterprise Architect (Sparx Systems) as their standard modelling tool to use this framework with the UAF Metamodel.
Models play a central role at VW
Model-based systems engineering is now used in many areas of the VW Group. In a joint webinar, Daniel Siegl (LieberLieber) and Hermann Gollwitzer (VW) explained the background to this and the role LieberLieber plays in implementing this fundamental change in development.
Configuration Management: Infineon relies on LemonTree
At Infineon‘s Munich location, the company relies on model-driven development with Enterprise Architect. In addition, the advantages of LieberLieber LemonTree were also recognized in order to be able to merge the models created directly in Git into different feature branches.
VW: Digital Assistant and Sequence Editor for Enterprise Architect
Volkswagen relies on Enterprise Architect along with bespoke LieberLieber modeling assistants to clearly and precisely communicate its requirements on infotainment software and systems development to its suppliers, and can now move ahead with plans to develop its own in-house infotainment software in the future.
Automotive: Continuous integration for model-based software development
In a department of a leading German automotive supplier, model-based software development is now being implemented to its fullest. This trend-setting move away from a traditional, document-centered method was only made possible by the use of LieberLieber LemonTree.
Preh: LemonTree for Product Family Engineering
The rapidly-growing automotive supplier Preh Car Connect GmbH is re-establishing its software development on the Product Family Engineering methodology. Preh engineers, already longtime Enterprise Architect users, were recently introduced to LemonTree from LieberLieber. The new concept was unveiled in a joint presentation and is nothing short of ambitious.
HIMA: Integration of LemonTree in Version Control Systems
The global leader in smart industrial security solutions, HIMA has used of Enterprise Architect since 2012. It was during a training course that HIMA became aware of LemonTree and recognized the great potential it holds for the versioning of EA models. Before long, a joint effort had been mounted to develop specific enhancements to LemonTree in order to satisfy HIMA’s stringent requirements on “smart safety”.
Hirschmann: Code Generation with Embedded Engineer
Hirschmann Car Communication is a leading German supplier of transmitter and receiver systems. The company has long based its systems development on Enterprise Architect. Now, in a preliminary project for a remote tuner, LieberLieber Embedded Engineer is being used to generate executable source code from their UML system model.
Hilti: Code Generation with Embedded Engineer
Following exhaustive tests, the renowned construction industry supplier Hilti decided on LieberLieber’s uml2code Code Generator for Embedded Systems for Enterprise Architect.
Petwalk: Code Generation with Embedded Engineer and Versioning with LemonTree
Petwalk, the Austrian specialist for automatic dog and cat doors, is on an expansion course. In order to meet the strict safety regulations required for access to the American market, the company sought the support of LieberLieber. Together, they are now developing a model-based solution that demonstrably meets all safety regulations.
