vízesésalapú

vízesésalapú is a term used in information technology and project management to describe a linear, sequential approach based on the Waterfall model. In this approach, development proceeds through distinct phases—requirements, design, implementation, verification, deployment, and maintenance—each typically completed before the next begins, with limited opportunities for revisiting earlier decisions.

Originating from the Waterfall model, a classic software development methodology described in the late 20th century, the term vízesésalapú is used in Hungarian literature to translate or adapt "waterfall-based" concepts. The Waterfall model is commonly associated with Royce's 1970 description, which highlighted its rigidity and the need for evaluation at multiple stages.

Typically used when requirements are well understood and changes are costly. It yields predictable schedules and thorough documentation. It is common in industries with strict regulatory requirements or where hardware integration is involved.

Advantages include clear milestones, up-front planning, and straightforward progress tracking. Disadvantages include low adaptability to change, late discovery of issues, and potential misalignment with user needs.
