SOFTWARE ENGINEERING

Detailed explanation-1: -A risk is any adverse situation that might affect the successful completion of a software project. The most important feature of the spiral model is handling these unknown risks after the project has started. Such risk resolutions are easier done by developing a prototype.

Detailed explanation-2: -Monte Carlo Simulation: A statistical method used to model and simulate potential project risks and their impact on project outcomes.

Detailed explanation-3: -The risk analysis phase is the most important part of the spiral model. During this phase, all available alternatives that may help develop cost-effective projects are considered and strategies for their use are determined. This phase is specially added to check and resolve all possible risks in project development.

Detailed explanation-4: -The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping.
