Modeling helps me understand, communicate, and validate requirements clearly. It transforms complex ideas into visual structures that everyone can grasp — from stakeholders to developers.
This section gathers all my articles about modeling in Requirements Engineering and IT. I explore UML, SysML, BPMN, and practical tools like draw.io and Camunda. Each text shows how modeling connects logic, structure, and creativity to create better systems.
1. Foundations of Requirements Modeling
Modeling starts with a mindset. Before drawing diagrams, I need to understand why modeling matters and how it supports communication and quality.
These articles give me the conceptual base — explaining the difference between models and design, the role of context, and how modeling languages help define structure.

2. Context and Information Structure Modeling
Every requirement exists within a context. Understanding this environment helps me define boundaries, relationships, and dependencies.
These texts explain how to model context, visualize external influences, and describe information structures that support consistency and traceability.

3. UML and Object-Oriented Modeling
UML gives me a language to describe systems precisely. It connects requirements with implementation through diagrams and relationships.
These articles help me understand UML concepts, from classes and attributes to relationships and generalizations. I learn how to use UML to describe both structure and behavior.

4. Dynamic Views and Model Behavior
Static structures are important — but systems live through behavior. Dynamic modeling helps me describe interactions, processes, and system reactions.
These articles introduce dynamic views, explaining how they connect user actions with system logic.

5. SysML and Advanced Modeling Concepts
When systems grow complex, SysML extends UML to cover structure, function, and flow. It helps me integrate textual and visual requirements.
These articles guide me through SysML fundamentals and show how to merge requirements into coherent, testable system models.

6. Modeling with draw.io
Draw.io is a flexible and free tool for modeling. I use it to build UML, flowcharts, and use case diagrams quickly.
These articles explain practical modeling steps using draw.io — perfect for visual learners and professionals who want to apply modeling directly in projects.

7. Model-Based Validation and Quality
Models are not just visuals — they are tools for validation. They help ensure that requirements are consistent, complete, and testable.
These texts show how model-based validation improves software quality and connects analysis with implementation.
