Meta-Model for Software Development

C.

The spiral model is actually a meta-model that incorporates a number of the software development models.

This model depicts a spiral that incorporates the various phases of software development.

The model states that each cycle of the spiral involves the same series of steps for each part of the project.

CPM refers to the Critical Path Methodology.

The software development models are frameworks that help to structure the software development process. Each model follows a specific sequence of phases or steps to complete the development process. The models include the Waterfall model, Spiral model, and Critical Path Model (CPM).

The Waterfall model is a linear sequential approach to software development, where each phase must be completed before the next phase can begin. This model follows a sequence of phases that include requirements gathering, design, implementation, testing, deployment, and maintenance.

The modified Waterfall model is a variation of the Waterfall model that allows for feedback loops between the phases to address issues as they arise.

The Spiral model is an iterative approach to software development, where each iteration goes through four stages: planning, risk analysis, development, and evaluation. Each iteration results in a prototype that is evaluated before moving to the next iteration.

The Critical Path Model (CPM) is a project management approach that focuses on identifying the critical path in the development process. The critical path is the sequence of tasks that must be completed on time for the project to be completed on schedule.

The software development model that is actually a meta-model that incorporates a number of the software development models is the Spiral model. The Spiral model combines elements of the Waterfall model and the iterative approach of the Agile methodology. The model includes planning, risk analysis, development, and evaluation, and uses feedback loops to address issues as they arise. The Spiral model allows for flexibility and adaptation throughout the development process, making it suitable for complex projects that require frequent changes and updates.
