Similarities Between Agile and Waterfall They perform the same activities, which include collecting requirements, designing, developing, testing, and deploying. The foundation of a project involves planning, bringing the project to life, and monitoring the project's progress in the two methodologies.

SDLC - Waterfall Model. The Waterfall Model was the first Process Model to be introduced. ... In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. The Waterfall model is the earliest SDLC approach that was used for software development.

Comparing Waterfall and Agile Project Success Rates From the Standish Group 2018 Chaos Report: The results for all projects show that agile projects enjoy a 60% greater chance of success than non-agile projects. Looking deeper, we find that “waterfall” projects are three times more likely to fail than agile projects.
