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, the laws of software evolution refer to a series of laws that Lehman and Belady formulated starting in 1974 with respect to software evolution. [1] [2] The laws describe a balance between forces driving new developments on one hand, and forces that slow down progress on the other hand. Over the past decades the laws ...
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).
The waterfall model is an implementation of a systems development process. [111] As the waterfall label implies, the basic phases overlap each other: [112] The investigation phase is to understand the underlying problem. The analysis phase is to understand the possible solutions. The design phase is to plan the best solution.
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 ...

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. [3]
It's a classic tale: You have last-minute guests coming over for dinner or a bake sale fundraiser you didn't find out about until the night before—and now you need to concoct some tasty treats ...
