Published on

The presentation slides from a talk I gave at XP2010 in Trondheim, Norway. Here are some metaphors that I find useful when describing software product development. In particular, they are useful for describing the basic principles of agile development and the lifecycle of a typical agile project.

  6. 6. “THE  POWER  OF  METAPHORS  IS  IN  THE  WAY  THAT   THEY  CHANGE  THE  SUBJECT  BY  BRINGING  NEW   THINKING  AND  IDEAS,  EXTENDING  AND  CHANGING   THE  WAY  THAT  A  PERSON  THINKS  ABOUT   SOMETHING.”

  19. 19. The  quality  exhibited  by  conversaDon,  in  language   and  behaviour,  during  which  each  party,  released   from  vanity,  inhibiDon,  and  preconcepDons,  treats   the  contribuDons  of  other  parDes  as  material  to   make  with,  not  as  posiDons  to  argue  with,  so  that   new  and  unpredictable  ideas  emerge.   COLLABORATION  
  20. 20.
