Documenta<on – The Problem • Systems and soAware are evolving –> ”Document Dept”
• What is important and to whom? The sender or the receiver?
• hVp://mar<nfowler.com/ieeeSoAware/whoNeedsArchitect.pdf
• Perhaps the most important is to write/visualize • Andy Hunt, Pragma<c Thinking

Explora<on SoAware Visualiza<on
• GeneraDng images instead of doing it by hand when we want to explore the informa<on (microstates).
• Informa<on visualiza<on is essen<al in making sense out of large data sets (microstates) by finding paVerns.
• Generate and Display for a specific purpose – Rela<onships between modules/components/classes/en<<es/…
