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 ...
The Waterfall model for software development is mistakenly attributed to Royce. Barry Boehm wrote in 1987: . Royce's 1970 paper is generally considered to be the paper which defined the stagewise "waterfall" model of the software process.
Big design up front (BDUF) is a software development approach in which the program's design is to be completed and perfected before that program's implementation is started. It is often associated with the waterfall model of software development. Synonyms for big design up front (BDUF) are big modeling up front (BMUF) and big requirements up ...

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.

DOD-STD-2167A (Department of Defense Standard 2167A), titled "Defense Systems Software Development", was a United States defense standard, published on February 29, 1988, which updated the less well known DOD-STD-2167 published 4 June 1985. This document established "uniform requirements for the software development that are applicable ...
In particular, it applies (with the name continuous design) to software development.In this field it is a practice of creating and modifying the design of a system as it is developed, rather than purporting to specify the system completely before development starts (as in the waterfall model).
It has also been used to illustrate the waterfall model of software development. [3] The origin of this cartoon appears to be from at least the late 60's, and possibly earlier. The original date and author are currently unknown, as is the exact original form.
