Classical waterfall model divides life cycle into phases:
feasibility study, requirements analysis and specification, design, coding and unit testing,
integration and system testing, maintenance.

Phases between feasibility study and testing
known as development phases.
Among all life cycle phases
maintenance phase consumes maximum effort.
Among development phases,
testing phase consumes the maximum effort.
Classical Waterfall Model (CONT.)
Most organizations usually define:

They also prescribe specific methodologies for:
