Reliable Software Tech Talk on Software Life cycle Model

Software Lifecycle Model talks about the various phases of software lifecycle and the order in which the phases are to be executed. Each company can choose its own software lifecycle model, but truth is requirement gathering, elicitation analysis, solution and validation is common for all the models. There are several types of software lifecycle models with each having their own set of advantage and disadvantages.

Software Lifecycle Model

In General Lifecycle Model, each phase produces deliverables required by the next phase in the lifecycle that is translated into design and code is produced based on it. Waterfall model, the least flexible and most obsolete of all lifecycle models; was developed to meet demands of complexities in aerospace products. V-Model, is a variant of waterfall model where a validation test is conducted in each developmental phase with similar abstraction.

The Incremental Model, makes use of multiple development cycles that are divided into smaller easily manageable iterations; with each passing through design and testing process. Prototype model, uses a prototype to build, test and rework until an acceptable result is finally achieved. Software provider and client play a key role to identify requirements based on which prototype is prepared. Spiral model is made up of planning, risk analysis, engineering and evaluation phases; and is ideal for complicated projects. It combines features of waterfall model and prototype models, with focus on risk analysis.

Rapid Application Development Model, makes use of reusable software components with focus on short development cycle. Made up of Business Modeling, Data Modeling, Process Modeling, Application Generation, Testing phases it focuses on cutting testing and development time. Fourth Generation Technique uses software tool to automatically generate source codes for high-level specification.

Agile software development methodology makes use of iterations that evolve through continuous inspection and adaptation. Adaptive Software Development, Extreme Programming (XP), Scrum, and Kanban are the most commonly used agile framework at present. Scrum is the most used process framework for agile development.
