In which systems building methodology are development stages organized sequentially?

The methodology where development stages are organized sequentially is known as the Traditional methodology. This approach typically follows a linear sequence of phases, often termed the Waterfall model. Each phase must be completed before the next one can begin, which includes stages like requirements analysis, system design, implementation, testing, deployment, and maintenance.

In this methodology, the focus is on thorough documentation and a structured process that allows for clear milestones and deliverables at each stage. The sequential nature is beneficial in projects where requirements are well understood and are unlikely to change dramatically during development. It promotes a systematic step-by-step progression through the lifecycle of application development, which can lead to more predictable outcomes.

By contrast, methodologies like Prototyping and Rapid Application Development (RAD) involve more iterative and flexible approaches, emphasizing user feedback and adaptability over strict sequential progression. In these models, stages may overlap or repeat, allowing for ongoing refinement based on user input and changing requirements.
