Describe computer software development life cycles
• Iterative
• Prototype
Iterative model:
Iterative development is a way of breaking down the software development of a large application into smaller chunks. An iterative life cycle model does not attempt to start with a full specification of requirements. The iteration involves the redesign and implementation of iteration is to be simple, straightforward, and modular, supporting redesign at that stage or as a task added to the project control list. The level of design detail is not dictated by the iterative approach. The analysis of iteration is based upon user feedback, and the program analysis facilities available. The project control list is modified in light of the analysis results. . It involves analysis of the structure, modularity, usability, reliability, efficiency, & achievement of goals.
