The final result faster and ensure customer satisfaction. As he fully participated in the process of building the program. Here the difference occurs when comparing this Ethiopia Telegram Number model with the previous one. In conclusion, As the customer here is one of the decision. Makers in building programs. While there his  role is limited to giving opinions about ready programs. Finally the spiral model, It is a waterfall model combined with the iterative method. Which is called a group of spirals starting from the basic spiral until the final spiral. It is used in companies for large, expensive, high-risk projects.
