The TheSpiral Model model is the whole process of software development which is divided into separate phases. In other words, 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. The\u00a0 different phases of the Spiral Model model are:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/bcisnotes.com\/thirdsemester\/wp-content\/uploads\/2020\/02\/spiral.jpg\" alt=\"The Spiral Model || Information System Development || Bcis Notes\" width=\"431\" height=\"398\" \/><\/p>\n<ul>\n<li><strong>Objectives Determination and Identify Alternative Solution\u00a0\u00a0<\/strong><\/li>\n<li><strong>Identify and Resolve the Risks<\/strong><\/li>\n<li><strong>Develop the Next Version of the Product<\/strong><\/li>\n<li><strong>Review the Plan for the Next Phase<\/strong><\/li>\n<\/ul>\n<p><strong>Objectives Determination and Identify Alternative Solution\u00a0<\/strong><\/p>\n<p>Requirements are gathered from the customers and the objectives are identified, elaborated, and analyzed at the start of every phase.

This phase also includes understanding the system requirements through continuous communication between the customer and the system analyst. At the end of the spiral, the product is deployed in the identified market.<\/p>\n<p><strong>Identify and Resolve the Risks<\/strong><\/p>\n<p>During the second quadrant, all the possible solutions are evaluated to select the best possible solution. Then the risks associated with that solution are identified and the risks are resolved using the best possible strategy. At the end of this quadrant, the Prototype is built for the best possible solution.<\/p>\n<p><strong>Develop the Next Version of the Product<\/strong><\/p>\n<p>During the third quadrant, the identified features are developed and verified through testing.
