Agile vs Spiral is a comparison of all the advantages and disadvantages of the Agile Software Development and Spiral Model software development models.
Spiral vs Agile. 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. Agile software development is an approach to software development under which requirements and solutions evolve through the collaborative effort of self-organizing and cross-functional teams and their customer(s)/end user(s). It advocates adaptive planning, evolutionary development, early delivery, and continual improvement, and it encourages rapid and flexible response to change.
Agile vs Spiral Model is often considered fictional. Since many developers believe that Agile and Spiral are one and the same, the name Agile was coined for marketing purposes. Agile is essentially a Spiral in which there are no plans for something that is not yet visible and that is not yet known. Agile is the planning of each individual stage of Spiral, and the Spiral is the planning of all Spiral's parts through Agile.
Difference Between Agile and Spiral Model is that most Spiral models of development still insist on big, up-front design. The focus is on the details of the system and how to use the system in the future. Knowing this, the system understands the stages of development and plan each of these stages. In Agile, on the contrary, the stages are planned independently of each other. Accordingly, disclosure of details is delayed.
