The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

The waterfall model is the earliest Systems Development Life Cycle approach used in software development. [ 3 ] The waterfall development model originated in the manufacturing and construction industries, [ citation needed ] where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in ...
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
Traditionally, construction has made use of manual labor such as tradesmen and subcontractors for tasks such as the installation of prefabricated elements. [6] In the industrialization phase, construction uses manufacturing processes and technology to perform off-site prefabrication, assembling building components off-site rather than at the point of installation.
The choice of construction method is a key aspect of the construction planning activity. The choice of construction method affects the extent to which construction prerequisites (e.g. Requirements analysis , Software design , .. etc.) are performed, the order in which they are performed, and the degree to which they are expected to be completed ...
In software development, the V-model [2] represents a development process that may be considered an extension of the waterfall model and is an example of the more general V-model. Instead of moving down linearly, the process steps are bent upwards after the coding phase, to form the typical V shape.
This diagram emphasizes several important interpretations of the Zachman Framework and its adaptation to information technology investment management. Progressing through the rows from top to bottom, one can trace-out the systems development life cycle (SDLC) which is a de facto standard across the Information Industry;
