LINEAR SEQUENTIAL MODEL / WATERFALL MODEL
CHARACTERISTICS: The output of one phase is the input of another phase in a linear sequential order. We work on one phase at a time. Work fashion is in a linear sequential order. ADVANTAGES: Cost-effective Less time consuming No pre-knowledge is required Secured mechanism Efficiency DISADVANTAGES: No working software is produced until late during the life cycle. It is rigid. Lack of intuitiveness. Lack of unification. A risk involving development. No centrality of the client. download notes
