Summary and Conclusions

Many common features can be discerned among the various object-oriented analysis and design methodologies:

• Iterative developmental approach used in nearly all methodologies
• Initial requirements often obtained as text in a simple index card format, e.g.:
  • User stories in XP
  • Use cases in RUP
  • Index cards in Prof. Chang's methodology
• Index cards also used in later-stage software design:
  • CRC cards- used in many object-oriented methodologies
  • Index cards of Prof. Chang have some utility here as well
• Typically, an emphasis on automated software testing
• In all methodologies, transformation to design and to code involves pattern recognition

A software application is a useful tool for in-depth learning about these methodologies!  ;-)
