Study Notes

Enterprise Architecture Modeling Guidelines

A model provides answers to specific business, application, and technology questions.
Distinguish between the model and its visualization. A model is a conceptual representation; a visualization is its visual form.
Models should be dynamic, including aspects likely to change over time.
Models should be concise, representing only relevant concepts and relations.
Use recognizable concepts and structures with stakeholder-appropriate names and types.
Maintain consistency in models. Use the same terms for similar concepts across models.
Model similar relations similarly.
Maintain consistent levels of abstraction.
Ensure models are complete, accurate, and correct.
Use design viewpoints aligned with objectives.
Include only elements contributing to modeling objectives.
Avoid irrelevant elements.
Make models self-explanatory.
Separate internal and external behaviors.
Collect feedback from stakeholders.
Use enterprise architecture layers and phases for grouping.

Guidelines for Readability and Usability

Internal Composition: Model elements starting with their internal structure.
External Support: Model elements moving upwards to show what supports them.
Realization: Direction towards how elements are realized by other elements.
Peer Cooperation: Model elements showing interactions with related elements.
Visual Complexity Reduction: Reduce concepts, elements, and relations in a model.

Gestalt Theory (Human Perception)

Proximity: Related items are placed together.
Similarity: Similar items are grouped.
Continuity: Suggests lines continue.
Closure: Incomplete shapes are perceived as complete.
Common Fate: Moving or acting alike triggers perception of a group.

Layouts and Symbols

Layouts: Basic patterns, alignment, spacing, symbol density, distinguish normal from exceptions.
Symbols: Match real-world characteristics; use similar shapes for similar concepts.
Directionality: Time dependencies from left to right. Avoid crossing lines.
Line Width: Highlight important relations using thicker lines.

Use of Color

Use color for similarity and to convey emotions, avoiding too many colors.
Prior knowledge influences interpretations of color.

Use of Text

Use domain-specific terminology.
Use proper naming conventions.
Text clarifies interpretations and associations.
