**SOFTWARE ENGINEERING** 1. Match the software process model on the left with the correct description on the right. waterfall model incremental model stepwise refinement model rapid prototyping model A. the phases of the software life cycle are followed rigorously in order B. the software is developed by building a core functionality first, and adding features to it later C. involves the creation of one or more periodic mock-ups that are reviewed by the customer D. a full version of the software is developed first, and the existing functionality is improved later 2. Despite the limitations of the waterfall model, it can still be somewhat practical for developing what kinds of software projects? (Select all that apply.) large enterprise systems programs that are relatively trivial in size systems that are very similar to other systems that have been previously built critical systems
