Passion for model-based Systems

We support visionary companies and people.

With model-based systems to entrepreneurial success

Successful companies achieve their goals because they have transparency about their current “as-is” status, know their target and how to reach it. With a model-based approach, objectives and tasks are developed on a solid basis and allow to reach the company goals.

We further developed the approach of Enterprise Architecture with the use of modelling. This allows a transparent, holistic visualization of the company’s current tasks.

Modeling creates the solid basis for innovation, change management and documentation. We support and accompany companies and organizations, partners and customers, with tools, methods, training and coaching.

We at Lieber.Group are the experts for modeling enterprise and system architecture.

We differentiate:

  • the information and application architecture for software / applications, data, roles, …
  • the technology and infrastructure architecture for digital and non-digital infrastructure, databases, etc.
  • the business architecture for business processes, products and services, …

We have a technical understanding of methods, processes and tools.

When introducing modeling in your company, we practice a pragmatic approach.

You do not have to start on the green field, but can keep your existing software and try out modeling within a pilot project.

It is important to adapt the modeling approach to your company or to the project. With this approach, you will attain the results you are focusing on.

Agile Structures

Relevance and transparency enables companies to move into agile structures.

Our four companies support and accompany our customers and partners in this task. Customer orientation comes first, not as a mandatory program, but because we are modeling enthusiasts ourselves.

With modeling, we shape the sustainable and resilient future together with our customers and our partners.

“We understand ourselves as enabler.”
