Spiral-Model
What is Spiral-Model?
The spiral model, also known as the spiral lifecycle model, is a systems development lifecycle (SDLC) model used in information technology (IT). This model of development combines the features of the prototyping model and the waterfall model. The spiral model is favored for large, expensive, and complicated projects.

W-Model
What is W-Model?
From the view of testing, all of the models presented previously are deficient in various ways:
* the test activities first start after the implementation
* the connection between the various test stages and the basis for the test is not clear
* the tight link between test, debug and change tasks during the test phase Read More...
Waterfall-Model
What is Waterfall-Model?
One of the first models for software development is the so-called waterfall-model. The individual phases i.e. activities, that were defined here are to be found in nearly all models proposed since. In this it was set out that each of the activities in the software development must be completed before the next can Read More...
V-Model
What is V-Model?
Many of the process models currently used can be more generally connected by the V-model where the “V” describes the graphical arrangement of the individual phases. The “V” is also a synonym for verification and validation.
The model is very simple and easy to understand. By the ordering of activities in time sequence and Read More...
