What was a defining characteristic of the original Waterfall software development approach?

• A. Replacing one application with a new version by copying over the entire codebase
• B. Releasing frequent, small incremental updates
• C. Emphasizing continuous integration
• D. Cloud-based deployments

Answer: (A)

The key idea behind the Waterfall approach is a linear, phase-by-phase process where work moves forward in a single direction—from requirements through design, implementation, verification, and maintenance—with little to no backtracking. Because the model aims to deliver a complete, finished system in a single, well-planned release, upgrades are typically handled by introducing a wholly new version of the application that replaces the old one, effectively copying over the entire codebase. This contrasts with modern practices that emphasize small, incremental updates, continuous integration, or cloud-based deployment, all of which involve more frequent, iterative changes rather than a single, complete replacement.
