Answer:
The linear sequential model of software development is
A reasonable approach when requirements are well defined.
Step-by-step explanation:
This type of software development model, called the linear sequential model, is also known as the classic life cycle or waterfall model. The model suggests a systematic, sequential approach to Software Development, starting at a design level and progressing through the processes of communication, planning, modeling, construction, and deployment, till the final stage of support. The model is simple to understand and use. With this model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. This is why requirements must be well-defined.
