This gradual and risk-aware approach is very similar to how the Spiral Model works in software development. Software projects are often filled with uncertainties. Customers may not know exactly what they want. Technologies may change during development. Security concerns may emerge unexpectedly. Budgets may fluctuate. Deadlines may shift. Traditional software development approaches struggle when dealing with such uncertainties. That's where the Sp...
