Waterfall Model

n.

Pronunciation

/ˈwɔtərˌfɔl ˈmɑdəl/

Definition

A sequential project management methodology commonly used in engineering and software design with separate, linear stages - requirements, analysis, design, coding, testing, and operations.

Waterfall Method is a structure where work flows through a progression of distinct phases. First, the requirements phase defines and documents system and software requirements. Next, the analysis phase generates schema, models, and business rules. The design phase produces software architecture, and the coding or implementation phase creates the software itself. Then, the testing or verification phase captures and removes issues with the system. Finally, the operations or maintenance phase implements and supports the final product. Robust requirement definition and early consideration of software structure are advantages of this method; however, it is less adaptable and iterative than other project management methods, such as Agile Development. Additionally, the entire process is completed before a usable product can be shown or given to clients.
