The waterfall model is a breakdown of developmental activities into linear sequential phases, meaning that each phase is passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. [1] This approach is typical for certain areas of engineering design.
A phase-gate process (also referred to as a waterfall process) is a project management technique in which an initiative or project (e.g., new product development, software development, process improvement, business change) is divided into distinct stages or phases, separated by decision points (known as gates).
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 ...
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. [3]
The expansion of the model to a dual-Vee concept is treated in reference. [3] As the V-model is publicly available many companies also use it. In project management it is a method comparable to PRINCE2 and describes methods for project management as well as methods for system development. The V-model, while rigid in process, can be very ...
According to Royce in the process model "the design iterations are never confined to the successive step", and for that model without iteration is "risky and invites failure". [3] As alternative Royce proposed a more incremental development, where every next step links back to the step before. The 'classical' waterfall model is figure 2.
A simplified version of a typical iteration cycle in agile project management. The basic idea behind this method is to develop a system through repeated cycles (iterative) and in smaller portions at a time (incremental), allowing software developers to take advantage of what was learned during development of earlier parts or versions of the system.
The method is a waterfall model divided in seven phases that have a clear start and end. Each phase delivers subproducts, called milestones. Each phase delivers subproducts, called milestones. It was used extensively in the Netherlands for ICT [ clarification needed ] projects in the 1980s and 1990s.
