Practical

• Factoring out
• Restricting/Extending
• Model only what you need

Practical Tricks

• Separate interface (on interrelations) from
  submodel
• Model one thing at a time use placeholders -
  KISS
• Move context-dependent data to the context
• Ignore representation for the model, but use it
  to demonstrate
• Test with examples
• Useful Design Patterns
• Composite
• Listener/Observer
• (Streams)
• Keep Diagrams simple
• Use activity diagrams
