Modellbibliothek
The Lehmann Systems Model Library is a fully closed and fully mirrored structure. All models, modules, and architectures are provided in a consistent, DOI‑based format and are identically represented in both German and English. The library forms the theoretical core of the system architecture and provides a stable, citable, and institutionally robust foundation for research, education, administration, and organizational practice.
The publications in the model library constitute the theoretical core components of an integrated, DOI‑based system architecture. They define the structural, communicative, and didactic foundations on which all further models, tools, and applications of Lehmann Systems are built. The models are formally described, internationally citable, and usable independently of individual preferences or institutional contexts. The library provides the overarching reference framework that offers research, administration, education, and organizational practice a consistent and reliable structure.
Systemic Foundations
PREA – Pre‑Architecture as the Foundational Layer of Systemic Orientation
10.5281/zenodo.18978281
Summary: PREA defines the foundational pre‑architecture layer of any system. It describes the underlying logic of reality that enables orientation, perception, and decision‑making. PREA forms the initial closure upon which META, MAMA, and PRA are built and provides the primary structural grounding of the entire architecture. The model is complete, non‑reconstructable, and applicable independently of roles, organizations, and contexts.
Foundations of an Integrated Organizational Architecture – A Conceptual Umbrella Publication
10.5281/zenodo.18754129
Summary: Conceptual umbrella publication of an integrated organizational architecture. It documents the scientific origins, meta‑structure, and referenced model components without disclosing internal mechanisms. The publication positions the overall architecture as a coherent, closed system rather than a collection of isolated models.
The Lehmann Cycle – Theoretical Architecture of Reality Processing
10.5281/zenodo.18811780
Summary: Universal four‑stage architecture of reality processing. It describes expectation formation, feedback integration, deviation assessment, and decision updating as a structural, culturally stable cycle. The model is domain‑independent and provides a robust reference for analyzing how systems interact with reality over time.
Functional Disproof and the Reality Argument: Closing a Gap in Argumentation Theory
10.5281/zenodo.18656309
Summary: Introduces Functional Disproof as a theoretical mechanism of refutation and the Reality Argument as a didactic routine. It defines reality as an independent argumentative instance and extends classical models of argumentation theory by adding a missing category that anchors arguments in observable outcomes.
THE NINE FIELDS – A Theoretical Structural Model of Functional Differentiation
10.5281/zenodo.18683950
Summary: Theoretical structural model of functional differentiation. It describes a three‑dimensional matrix of three levels and three layers, generating nine analytically distinguishable fields that map structural relations formally, context‑independently, and non‑operationally. The model provides a stable grid for positioning roles, processes, and systems.
Structural Phenomena Framework (SPF5) – Extended Conceptual Outline for Non-Operational Theoretical Inquiry
10.5281/zenodo.18726298

It describes theoretical, non‑operational constellations without deriving functional or domain‑specific applications. SPF5 serves as a high‑level lens for identifying recurring structural phenomena across systems.
The Four Structural Divergences Model – Theoretical Model Core
10.5281/zenodo.18649108
Summary: Theoretical core of the divergence model. It defines four structural divergences — reality, role, situation, and relationship — as causes of communicative success or failure. The model is minimalist, complete, and internationally operationalizable as a communication framework.
Reality as Orientation: Why Schools Must Teach the Strongest Argumentative Instance
10.5281/zenodo.18781025
Summary: Analysis of the neurocognitive, societal, and educational significance of reality as the strongest argumentative instance. It shows how reality reduces cognitive load, prevents manipulation, and strengthens orientation in educational transitions and decision‑making processes.

Predictive Reality Architecture (PRA) – Formale Strukturkomponente
10.5281/zenodo.18923188
Summary: Formal description of the architectural dimension Form within the Predictive Reality Architecture. It defines structural properties, systemic boundaries, and the functional role of Form as an independent architectural layer. The model is non‑operational, context‑independent, and designed as a theoretical foundation for the complete PRA.
Predictive Reality Architecture (PRA) – Öffentliche Architekturbeschreibung
10.5281/zenodo.18840326
Summary: Closed, domain‑agnostic architecture for describing predictive reality. It encompasses Mechanics, Form, Movement, and an implicit meaning field as a coherent system. The architecture is non‑operational, non‑extendable, and not reconstructable, and serves as a structural foundation for scientific, organizational, and societal applications.
SUITPOINT – Module
Suitpoint = the functional point at which it is decided whether a situation works or not.
Summary
The Suitpoint reduces any situation to a single functional core point. It collapses complexity, makes the situation thinkable, decidable, and controllable, and reveals where the real decision occurs. Cognitive overload drops because the functional core becomes visible. Emotional activation decreases because ambiguity disappears. Action becomes targeted, effective, and reality‑bound, as the Suitpoint shows what the situation functionally depends on.
Core Modules
The foundational modules define the universal conditions under which any system perceives reality, creates meaning, and acts responsibly.
Reality
Summary: Reality is the highest verification instance of any system. It validates expectations, limits interpretation, and prevents systemic collapse.
Communication
Summary: Communication is the operative channel through which reality becomes visible and meaning becomes transferable.
Meaning
Summary: Meaning is the semantic instance that enables orientation, comparability, and the formation of markers.
Order
Summary: Order is the structural instance that makes reality measurable and communication stable.
Neutrality
Summary: Neutrality is the evaluative instance that prevents distortion, roles, moral framing, and psychological projection.
Responsibility
Summary: Responsibility is the operative instance of accountability: task + authority. Without it, systems collapse even when order exists.
Organizational Modules
The organizational modules describe the functional components that define a system’s structure, processes, resources, responsibilities, interfaces, and priorities.
Structure
Summary: Structure defines the formal, stable elements of an organization. It establishes responsibilities, levels, boundaries, and functional arrangements.
Process
Summary: Process describes the repeatable sequences that bring tasks, decisions, and information into a stable order.
Resources
Summary: Resources include time, personnel, knowledge, infrastructure, and budget. They determine the system’s actual capacity to act.
Accountability
Summary: Accountability clarifies who is answerable for what. It links tasks, authority, and consequences.
Interfaces
Summary: Interfaces define transitions between roles, levels, systems, or organizations. They prevent information loss and friction.
Priority
Summary: Priority determines what is addressed first, later, or not at all. It directs focus, sequencing, and resource allocation.
Meta Models
The meta models do not describe the content of the models (these are fully contained in A), but their systemic role, their architectural function, and their position within the overall architecture. They define how the models are structurally connected, how they form levels, and how they operate as a closed architecture. The D‑level is therefore the meta‑structure of the model library.

It forms the practical layer of the system architecture and provides licensable, auditable, and institutionally robust structures.
The implementation architecture is divided into three classes:
- Major Curricula (30 ECTS) – fully study‑eligible, ECTS‑compatible academic programs
- Small Curricula (6–12 ECTS) – modular, study‑eligible curricula
- Systemic Implementation Standards – non‑study‑eligible but licensable standards
