Our services
We offer a wide range of consulting, training, research and development.
Strategic and System oriented Management
We develop strategies and measures based on interactive holistic system analysis.

Our approach provides a common and fact based understanding of the complex interdependencies and therefore security in the decision making - whether this is a company or NGO, a region, a city or a community or an individual.

Holistic System Analysis
Only in an iterative process of holistic system analysis does the system and its interrelationships become accessible to those involved. Our holistic system analysis enables you to track and analyse complex interdependencies and to identfy powerful levers and chances. Through various forms of visualization and fuzzy simulation the insights and results can easily be documented and communicated transparently.
Our computer-aided System Logics Tools support interactive cooperation and the joint development of future-proof strategies and sustainable measures.
Development of modeling tools and simulation games
We also develop new products and business tools for system modeling, evaluation and simulation based on many years of consulting and training practice.
Our iterative and evolutionary process
The process of a holistic system analysis is characterized through mainly eight iterative steps, which have been assembled by System Logics T.T. on the basis of various concepts of the system thinking sciences. Gabriele Harrer-Puchner sharpend and consolidated the process through many years of both practical applications and research.

The process is supported by own webbased system modeling and simulation tools and online games in continuous and client specific further developments.
What will you get?
Clear understanding of a business conception - as a complex system
Our system experts cover all fields of businesses with professional expertise and long years practical experience. Each project is designed together with our clients in order to develop each project with comprehensible results, effectiveness and transparency.
You save your time and wrong investments
Our process guides you from the early beginning in a structured and evolving way to identify the true levers, critical and risky variables, blind spots or unknown chances in your system.
Productivity elevation
The common and fact-based knowledge about the identified levers and strategical lanes makes sure, that all participants know the common targets and ways how to reach them.
