The waterfall model is the earliest SDLC approach that was 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 the development process.
Software prototyping is about creating prototypes, i.e. incomplete versions of the software program being developed.. The basic principles are: [1] Prototyping is not a standalone, complete development methodology, but rather an approach to try out particular features in the context of a full methodology (such as incremental, spiral, or rapid application development (RAD)).
Software development. The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping.
Software development. 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.
Agile software development methods have been extensively used for development of software products and some of them use certain characteristics of software, such as object technologies. [133] However, these techniques can be applied to the development of non-software products, such as computers, medical devices, food, clothing, and music. [ 134 ]
Phase-gate process. 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).
Winston W. Royce. Winston Walker Royce (August 15, 1929 – June 7, 1995) was an American computer scientist, director at Lockheed Software Technology Center in Austin, Texas. He was a pioneer in the field of software development, [1] known for his 1970 paper from which the Waterfall model for software development was mistakenly [2] drawn.
SSADM is a waterfall method for the analysis and design of information systems.SSADM can be thought to represent a pinnacle of the rigorous document-led approach to system design, and contrasts with more contemporary agile methods such as DSDM or Scrum.
