Spiral
The Spiral model is an evolution of traditional software development approaches, such as the waterfall model. It combines iteration with a sequential risk analysis at each stage of the project. The Spiral model divides the development process into several cycles, each consisting of four phases: goal definition, risk analysis, development, and planning for the next cycle.
The main idea of the Spiral model is that each new cycle allows the team to learn from the experience of the previous one and make more informed decisions at the next stage. This ensures a high degree of adaptability and enables effective project risk management.

Throughout each cycle of the spiral model, risk assessment and prioritization takes place, allowing teams to respond promptly to potential problems and work on their resolution. This helps ensure project stability and reduces the likelihood of failure.
The spiral model also encourages active collaboration between the development team and clients. Interested parties receive regular reports on the project's status, and their feedback is used to make changes and improve the product.
