What is another name for the *Waterfall* approach in systems development?

The Waterfall approach in systems development is indeed commonly referred to as the System Development Life Cycle (SDLC). This term describes a structured, linear methodology where each phase of development must be completed before the next phase begins. The Waterfall model is one specific implementation of this approach, emphasizing sequential progress through clearly defined stages such as requirement analysis, system design, implementation, testing, deployment, and maintenance.

Referring to it as the System Development Life Cycle encompasses the broader concept of a structured framework for developing information systems and software, which can include various models like Waterfall, but specifically highlights the sequential nature and lifecycle of system development activities. This understanding of the Waterfall method as part of the SDLC is critical in both theoretical studies and practical applications within information systems projects.
