Activity History

The following table gives a short overview about the beginnings and the activities related to the Fundamental Modeling Concepts (FMC). All listed events and projects were organized by Prof. Dr.-Ing. Siegfried Wendt who is the originator of the Fundamental Modeling Concepts (FMC).

Hasso-Plattner-Institute for Software Systems Engineering GmbH,
Professorship of Prof. Dr.-Ing. Wendt, (Potsdam, Germany)

2004 - today

  • Co-founder and member of the supervisory board of the ARCWAY AG as successor of PLAN S GmbH. ARCWAY AG offers FMC based coaching and courses. A product called COCKPIT is also available.

2003 - 2004

  • Co-founder and CEO of the PLAN S GmbH which does software development projects based on FMC


  • Construction phase of HPI is finished, so Prof. Dr.-Ing. Wendt retires as CEO.
    SPIKES is renamed to FMC.

2001 - 2003

  • Apache Modeling Project. The beginnings of the Apache Modeling Project was a modeling course in which students have to model a sample system, namely the HTTP-Webserver "Apache".
    Then it became the Apache Modeling Project. The information collected during preparation of the modeling course is now being merged into a document. Making it an example how to model and document complex systems with FMC.

1998 - 2002

  • Person of charge during construction of the Hasso-Plattner-Institue (HPI) in Potsdam as a education and research facility.
    CEO of the HPI; this institute is an approach to establish an engineering culture in the domain of software engineering with emphasis on communication and modeling techniques (especially FMC)
University of Kaiserslautern,
Department of Electrical Engineering and Information Technology,
Professorship of Prof. Dr.-Ing. Wendt, (Germany)

1996 - 1998

  • Formation and leading of the Software Engineering Lab (SEL)
  • A/3 - Architecture definition through Application Analysis (German: Architekturfindung durch Anwendungs-Analyse)
    Goal of A/3 was to find reusable architecture patterns for SAP R/3® applications
  • Timeless - Document management system with a strong library metaphor

1994 - 1995

  • Foundation and leading of the SAP Architecture Team
    Definition of the SAP R/3® successor systems architecture considering the architecture of the basic SAP R/3® system and architecures of SAP R/3® applications.

1990 - 1994

  • Leading analysis of basic SAP R/3® system
  • Creation of the so-called SAP Blue Books. These are documents describing the basic SAP R/3® system with the FMC. They constitute the basis of development and training today.
  • Formation of the SAP department "Software Basis Modeling" (today: "SAP Technology Modeling")
  • Consulting and accompanying documentation of projects with tight coupling to the basic SAP R/3® system.
  • Evaluation of external technologies and systems.

1977 - 1989
(Siemes AG)

  • Research: SYRUP - research assignment of the "Bundesministerium für Forschung und Technologie (BMFT)"
  • research on involvement of FMC in the Software Process
  • research on tool support for such a FMC based Process
  • Analysis of BS2000 - main frame operating system of Siemens
  • Application of predecessor of FMC to BS2000 the main frame operating system of Siemens
  • Development of BORIS - Block-Oriented Interactive Simulator (German: Block Orientierter Interaktiver Simulator)
  • Development of the tool "BORIS" in order to simulate any dynamic and informational system.
  • Agents and locations (FMC's main components of compostional structures, associated diagram type 'block-diagram') could be sperately described and then connected to build up the system to be simulated.
  • Development of CALVADOS - Computer-Aided Logic Verification And Documentation of Software
  • Development of an infrastructure and tools supporting a FMC based Software Process.
  • ATMOSPHERE - research assignment (European support programme in the framework of ESPRIT — European Strategic Programme for Research and development in Information Technology)

1975 - 1977
(Siemens AG)

  • Analysis of GOLEM - associative retrieval system of Siemens
  • Analysis project in cooperation with the Siemens departement "Siemens Analysis" in order to find suitable abstraction and presentation concepts
University of Hamburg,
Department of Computer Science,
Professorship of Prof. Dr.-Ing. Wendt, (Germany)


  • Initial enclosure conference "Lüneburger Heide"
    The goal of the enclosure conference at the "Lüneburger Heide" was to identify problems within the software industry. The main problems were identified in the field of human communication: intransparency of descriptions (discrepance of what is meant and what is expressed) and information monopoly (information is not shared).
