Sequential Development
Sequential Development is a software development methodology where the project progresses through a series of linear, distinct phases, such as requirements gathering, design, implementation, testing, and maintenance, with each phase completed before moving to the next. It is often associated with traditional models like the Waterfall model, emphasizing thorough planning and documentation upfront. This approach is characterized by minimal overlap between phases and a focus on completing one stage fully before proceeding.
Developers should use Sequential Development for projects with well-defined, stable requirements and low uncertainty, such as government contracts, safety-critical systems, or large-scale infrastructure projects where changes are costly. It is suitable when the scope is clear from the start, allowing for detailed planning and risk management, and when regulatory compliance or extensive documentation is required. This methodology helps ensure predictability and control over timelines and budgets in structured environments.
