Describe Spiral Model

Question

Describe in brief the Spiral Model.

Answer 1

In Spiral Model, a cyclical and prototyping view of the software development is described. Test are explicitly illustrated (risk analysis, validation of requirements and of development) and the test stage is divided into stages. The test actions comprise module, integration and acceptance tests. Though, in this model the testing as well follows the coding. The exception to this is that the test plan must be constructed after the design of system. The spiral model as well recognizes no activities related with the elimination of defects.
