SDLC 面试题与答案

Question: Briefly describe the phases in the Incremental model.

Phases of the incremental model are the same as waterfall i.e. Requirements, design, implementation, testing, and maintenance.

However, instead of following the waterfall once and for all linearly, the incremental model takes a different approach. These phases are repeated incrementally as business value is delivered incrementally as well.

For every single phase and increment a waterfall model is followed. The waterfall model is then put in a cycle of increments along with verification of requirements, and design.
