Genislab TechnologiesThe spiral model is similar to the incremental model, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, Risk Analysis, Engineering and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model). The baseline spiral, starting in the planning phase, requirements are gathered and risk is assessed. Each subsequent spirals builds on the baseline spiral. Its one of the software development models like Waterfall, Agile, V-Model. [Read more…] about What is Spiral model- advantages, disadvantages and when to use it?

What is Iterative model- advantages, disadvantages and when to use it?
An iterative life cycle model does not attempt to start with a full specification of requirements. Instead, development begins by specifying and implementing just part of the software, which can then be reviewed in order to identify further requirements. This process is then repeated, producing a new version of the software for each cycle of the model.

What is Agile model – advantages, disadvantages and when to use it?
Agile development model is also a type of Incremental model. Software is developed in incremental, rapid cycles. This results in small incremental releases with each release building on previous functionality. Each release is thoroughly tested to ensure software quality is maintained. It is used for time critical applications. [Read more…] about What is Agile model – advantages, disadvantages and when to use it?
What is RAD model- advantages, disadvantages and when to use it?
RAD model is Rapid Application Development model. It is a type of incremental model. In RAD model the components or functions are developed in parallel as if they were mini projects. The developments are time boxed, delivered and then assembled into a working prototype. [Read more…] about What is RAD model- advantages, disadvantages and when to use it?
What is Incremental model- advantages, disadvantages and when to use it?
In incremental model the whole requirement is divided into various builds. Multiple development cycles take place here, making the life cycle a “multi-waterfall” cycle. Cycles are divided up into smaller, more easily managed modules. Incremental model is a type of software development model like V-model, Agile model etc. [Read more…] about What is Incremental model- advantages, disadvantages and when to use it?
