Water fall model is a sequential step of processeds
follewed. It starts with requirement gathering,analysis,
design, coding, implementation, maintanence. You always
finish one process and go to next. You cannot go backwards.
Spiral model mainly invloves risk analysis. You gather the
requirements analyse the risk then you engineer the code
and further implement. In a spiral the radius indicates the
project cost and the spiral of the sector indicates the
progress.
