Answer Posted / krish
Water Fall Model: this is the first SDLC model developed so
there are many disadvantages.
in waterfall maodel after completion of 1 phase, the next
pahse starts b'cos the output of 1 phase is the input to
the next phase.
Ex: until the release of initial build testing team is
almost idle..they jus study the requirement docs &
understand the req's b4 they get the build from dev team.
Srs ---> Design---> coding--->testing--->maintenance phase.
it is time consuming cos if ne changes in the functionality
hapens or if u find ne bug then total sdlc has to b
excecuted once again like if u wanna add ne new requirement
it is cost effective.
manpower is wasted in this model cos the testers has to b
idle unless they get the build from dev team
