Waterfall  

•  Requirements  specifica(on  •  Design  •  Construc(on  (AKA  implementa(on  or  coding)  •  Intergra(on  •  Tes(ng  and  debugging  (AKA  Valida(on)  •  Installa(on  •  Maintenance

Agile  

•  Agile  Manifesto  •  In  February  2001,  17  so)ware  developers  met  at  the  Snowbird,  Utah  resort,  to  discuss  lightweight  development  methods.    

•  They  published  the  Manifesto  for  Agile  So)ware  Development

Twelve  principles  underlie  the  Agile  Manifesto  

•  Customer  sa(sfac(on  by  rapid  delivery  of  useful  soLware  •  Welcome  changing  requirements,  even  late  in  development  •  Working  soLware  is  delivered  frequently  (weeks  rather  than  months)  •  Working  soLware  is  the  principal  measure  of  progress  •  Sustainable  development,  able  to  maintain  a  constant  pace  •  Close,  daily  co-­‐opera(on  between  business  people  and  developers  •  Face-­‐to-­‐face  conversa(on  is  the  best  form  of  communica(on  (co-­‐loca(on)  •  Projects  are  built  around  mo(vated  individuals,  who  should  be  trusted  •  Con(nuous  aYen(on  to  technical  excellence  and  good  design  •  Simplicity  •  Self-­‐organizing  teams  •  Regular  adapta(on  to  changing  circumstances
