V-model (software development)
open-in-new
<p>In <a href="/facts/Software_development/UUfsAaYY">software development</a>, the V-model represents a <a href="/facts/Software_development_process/cIDtuNPN">development process</a> that may be considered an extension of the <a href="/facts/Waterfall_model/uQGzoBKH">waterfall model</a> and is an example of the more <a href="/facts/V-model/BI5sYz27">general V-model</a>. Instead of moving down linearly, the process steps are bent upwards after the <a href="/facts/Source_code/o9J6Jv23">coding</a> phase, to form the typical V shape. The V-Model demonstrates the relationships between each phase of the development life cycle and its associated phase of <a href="/facts/Software_testing/VoXzG9Tb">testing</a>. The horizontal and vertical axes represent time or project completeness (left-to-right) and level of abstraction (coarsest-grain abstraction uppermost), respectively. </p>
