1. Prototyping allows testing designs and ideas at low cost before committing to a final product. This helps surface issues and risks early.
2. Iterative testing and refining of models helps improve the design and uncover potential problems before implementation.
3. Modelling complex systems breaks them down into simpler components that are easier to analyze for risks and errors.
The modelling process helps manage risks by allowing experiments and "what if" scenarios to be tested inexpensively before real-world deployment.
