Iterative and incremental development is any combination of both iterative design (or iterative method) and incremental build model for development. Usage of the term began in software development , with a long-standing combination of the two terms iterative and incremental [ 1 ] having been widely suggested for large development efforts.
V-Model (software development) - an extension of the waterfall model; Unified Process (UP) is an iterative software development methodology framework, based on Unified Modeling Language (UML). UP organizes the development of software into four phases, each consisting of one or more executable iterations of the software at that stage of ...
The unified software development process or unified process is an iterative and incremental software development process framework. The best-known and extensively documented refinement of the unified process is the rational unified process (RUP). Other examples are OpenUP and agile unified process.
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.

One of the differences between agile software development methods and waterfall is the approach to quality and testing. In the waterfall model, work moves through software development life cycle (SDLC) phases—with one phase being completed before another can start—hence the testing phase is separate and follows a build phase. In agile ...
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.
The waterfall model is the earliest Systems Development Life Cycle approach used in software development. [3] When it was first adopted, there were no recognized alternatives for knowledge-based creative work. [4]
The rational unified process (RUP) is an iterative software development process framework created by the Rational Software Corporation, a division of IBM since 2003. [1] RUP is not a single concrete prescriptive process, but rather an adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process ...
