MODELING INFRASTRUCTURE

LieberLieber’s vast project experience has resulted in an effective method for creating modeling infrastructures that meet even the most complex requirements.

The optimal use of modeling for your company is ensured by targeted design, adaptation and expansion of your infrastructure.

  • Use your existing infrastructure
  • Create an adaptation concept
  • Work efficiently even in distributed teams
  • Product line development for modeling
  • Re-use of established versioning concepts for models
  • Fulfillment of the ISO 26262 standard

LieberLieber EXPERTISE

LieberLieber has experience with a wide variety of infrastructures and is familiar with transforming them into a productive modeling environment. In doing so, we carry over the specifications and internal processes of your company, for example with regard to versioning, variant management or product line development. We align our strategy and the tools used to seamlessly integrate modeling into the existing setting. Because we realize that newly-added modeling tools should not dictate the processes, but must of course adapt to them.

Our product in your modeling infrastructure

Special requirements on software and systems development often arise in a modern modeling infrastructure when development is handled in distributed teams. A central aspect is the merging of parallel model versions (Diff & Merge). This is one of our key areas of specialization:

  • Comparison and merging of Enterprise Architect models
  • Parallel editing of models via optimistic model versioning
  • Seamless integration in Subversion, Git, PTC or other VCS
  • Model branches
  • Changes are shown clearly and intuitively (incl. Merge Preview)
  • Review function for calculated changes

Webinar: SysML-Light with Enterprise Architect (German)

7.3.2022, 13:00 – free participation
The ballast-free and practical introduction to Model-Based Systems Engineering
Many organisations find it difficult to get started with MBSE using SysML. Among other things, they are faced with the challenge of having to decide how to tailor the general modelling language SysML with its 9 diagram types and many model elements to the project-specific needs. After all, not all diagram types and model elements should be used.

Webinar Agile MBSE: Thursday 10.3.2022, 14:00 – 14:45, LieberLieber Software + Nanga Systems

A constantly and ever faster changing world requires new working methods and tools in Systems Engineering. For this reason, there has been a shift towards Model Based System Engineering (MBSE) for quite some time. However, especially in agile settings, there are many detailed issues to be resolved in the development process to meet the required traceability and other conditions.

Whitepaper: Is suitable versioning possible at all?

In our everyday practice of model-based systems engineering in various branches of industry, we repeatedly encounter the question of precise and easy-to-handle versioning of models. This question is becoming increasingly important due to legal regulations, stricter safety regulations and the significant increase in product variants.

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.

Continuous Integration with Enterprise Architect

In the course of the increasingly agile orientation in software development, our customers ask us again and again whether modelling and agility go well together. Our opinion on this is quite clear and has also been proven in various studies: Only with properly applied modelling can agile processes be implemented at all in the face of increasing complexity, if you also want to document all regulations and requirements in a comprehensible way.

WHAT CUSTOMERS ARE SAYING

Preh Car Connect
As our company continues to see strong growth and the implementation of numerous series projects, we can effectively use components of our own software again and again. So far, however, this has only been possible through the laborious manual copying of software architecture models. Together with LieberLieber, we are now working on a project that will automate such processes. LemonTree is an important building block for us in order to be able to implement these development steps faster and more easily.

Tim Michaelis
Software architect at Preh Car Connect

Petwalk
LieberLieber’s approach is very pragmatic: You can continue to use existing software and still switch to a model-based approach when it makes sense. This makes it much easier for us to decide on the fly whether or not to take this step. This also allow us to intensify our cooperation with LieberLieber on an ongoing basis, trying out new things over and over again.

Klaus Kindl
Gründer und Geschäftsführer von Petwalk Solutions

HIMA Paul Hildebrandt GmbH
“In general, standards such as IEC 61508 demand the application of configuration management. This refers to all artifacts, including UML models. LemonTree from LieberLieber is our key to revealing the changes that have been made to a revision.”

Customer Success Stories

Petwalk

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.

Preh

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

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”.
