Fixed Requirements
Fixed Requirements is a software development approach where project requirements are defined, documented, and agreed upon upfront before development begins, with minimal or no changes allowed during the project lifecycle. It is commonly used in traditional methodologies like Waterfall to ensure predictability in scope, timeline, and budget. This approach contrasts with agile methods that embrace changing requirements through iterative development.
Developers should use Fixed Requirements in projects with well-understood, stable needs, such as regulatory compliance systems or legacy system migrations, where scope clarity is critical to avoid costly rework. It is suitable when stakeholders have clear, unchanging specifications and the project requires strict adherence to initial plans for contractual or financial reasons. However, it can be rigid and less adaptable to evolving business needs compared to agile approaches.
