The beginning of a project lays the groundwork for the rest of
the project. The purpose of this phase is to set the framework
for the project, which involves: - Traditional SDLC based
Waterfall Model - Iterative Spiral Model - Rational Unified
Process - Agile Process model - Scrum Process Traditional SDLC

primarily takes care of the analysis phase, then the designing
