is one of the earliest and most traditional software development models.
Waterfall MOdel
Who introduced Waterfall model?
Winston W. Royce in 1970
it follows a linear and sequential apprach. where each development must be completed before the next
Waterfall model
- Sequential and rigid (each phase must finish before the next starts).
- Documentation-heavy (detailed records at each stage).
- Requirements must be clear and stable before development begins.
- Testing comes late in the process.
Waterfall model
foundational SDLC approach that offers simplicicity and structure
Waterfall model
that emphasizes quick prototyping, fast iterations, and user involvement over lengthy documentation and rigid planning.
Rapid Application development
focuses on building functional prototypes quickly, gathering feedback from users, and refining the system in multiple iterations until the final product is achieved.
RAD
is especially useful when project requirements are not fully known at the start or are expected to change during development.
RAD
is a software development approach where a prototype (an early working version of the software) is built, tested, and refined until it evolves into the final product
Prototyping model
Instead of trying to gather and finalize all requirements upfront, this model allows developers and users to interact with an initial version of the system, provide feedback, and continuously refine the software.
Prototyping model
is an early approximation of a final system or product. It is not the complete software but a partial implementation that demonstrates core features, user interface, or workflow.
Prototype
Prototype that is built quickly and discarded once requirements are clarified.
Throwaway/Disposable
Prototype that is continuously refined until it becomes the final system.
Evolutionary
Prototype that is Developed in pieces (modules) and integrated
Incremental
Prototype that is Built rapidly using reusable components
Extreme
is an effective approach when project requirements are unclear or evolving. By engaging users early and often, it ensures that the final system meets user needs and expectations
Prototyping model
is a software development approach where the system is designed, implemented, and tested in small increments until the final product is complete.
Incremental
. Instead of delivering the entire system at once, developers divide it into smaller modules or parts. Each increment adds new functionality to the software, and the product grows progressively.
Incremental Model
This model is considered a balance between the Waterfall Model and Iterative Model — it provides structure while still allowing flexibility for changes.
Incremental model
is an effective approach when projects need early delivery, gradual improvements, and flexibility in handling changing requirements.
Incremental model
While it requires careful planning and can be costly in integration, its benefits in terms of early usability, reduced risk, and customer satisfaction make it one of the most widely used models in modern software development.
Incremental mdoel
The ____ combines elements of linear and parallel process flows.
incremental model
The ___ applies linear sequences in a staggered fashion as calendar time progresses
incremental model
is a powerful software development approach that allows systems to evolve through repeated cycles of development, testing, and feedback.
Iterative model
