LieberLieber: Your Enterprise Architect specialist

LieberLieber is the skilled Enterprise Architect (Sparx Systems) specialist with decades of experience in the development of customer-specific models. Our LemonTree and Embedded Engineer extensions make working with models faster and more efficient. We focus on three main areas of expertise:

Model-Based Systems Engineering

Modern electronic systems have to fulfill more and more requirements and therefore often become very complex. For decades, a proven means for reducing this complexity has been the use of models (architecture, mechanical engineering, etc.).

More …

Modeling Infrastructure

Any company’s established IT infrastructure can be adapted for efficient modeling. It is essential to make the best possible use of existing structures and available data when creating an interactive working environment for modeling teams.

More …

Integration with Enterprise Architect

Modern IT solutions utilize data originating from many sources. The best and most efficient way to handle this diversity is with a model-based approach. Our years of experience have provided us with the know-how required to connect such data sources to Enterprise Architect in the best possible way.

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.
