Concept explainers
Waterfall model:
Waterfall model concerns with the sequential completion of the stages in software development life cycle. Software development life cycle includes requirement analysis, design, implementation and testing stages. Each stage is completed separately.
The approach of waterfall model states that each stage in the software development life cycle must be completed before the beginning of the next stage. It requires the flow of activities in a sequential order and a stage is initiated only after successful completion of the previous stage.
Incremental and iterative paradigm:
Incremental and iterative paradigm is a combination of both incremental paradigm and iterative paradigm.
Incremental approach uses a partial implementation of the whole system. It is a combination of one or several waterfall models. It includes the requirement analysis, design, implementation, and testing stages to be performed on the incremental basis until the successful completion of software. It adds some new functionality in each small increment. Iterative paradigm uses addition of new functionality in a repetitive manner.
Incremental and iterative paradigm develops the software in small increments and in iterative or repetitive cycles.

- The spiral model of software development may be advantageous in a variety of ways for both the waterfall model and the prototyping model; what are some examples of these ways?arrow_forwardThe waterfall method is a software development life cycle (SDLC) model that encompasses distinct phases. It is plausible that this is the location where Barry Boehm's inquiry was initially initiated.arrow_forwardFor both Waterfall and Prototyping, the spiral model of software development may be beneficial in various respects; what are some examples?arrow_forward
- What are three benefits that incremental development has over the more conventional waterfall style of software development?arrow_forwardThere are a number of ways in which the spiral model of software development may benefit both the Waterfall and Prototyping methodologies; what are some?arrow_forwardIn what ways are incremental and waterfall approaches the same and different? What characteristics do they share?arrow_forward
- What are three advantages that incremental development provides over the more traditional waterfall approach to software development?arrow_forwardIn the context of software development, what are the key differences between throwaway prototyping and evolutionary prototyping? When is each approach most appropriate?arrow_forwardIs there a link between the degree of cohesion and the degree of coupling in software development?arrow_forward
- This inquiry pertains to the distinction between cohesion and coupling, and their respective variations within the domain of software design and development?arrow_forwardIn the context of software design and development, what is the link between cohesion and coupling, and how do they differ from one another?arrow_forwardWhat exactly is the Waterfall model in software development?arrow_forward
