What is the difference between sdlc and waterfall model

Aside from the above-mentioned cases, waterfall is also the best model for projects that migrate from one platform to the next, with the condition that all requirements remain the same. All of the possible requirements of the system that will be developed are identified and documented in this stage. From the first phase, the requirement specifications and the system design will be prepared. This allows developers to specify system requirements and hardware, as well as define the complete system architecture.

Once the implementation stage is done, all units are integrated into a system following the testing process. Post-integration is a step where the entire system is tested for any failures. When both functional and nonfunctional testing is done, the product is either released into the market or deployed in the client environment.

There are possible issues that could come up once the software is deployed. To address those problems, developers release patches as part of the maintenance stage. Better versions might be released to improve the product even more. Maintenance is conducted to deliver these changes to the client environment.

This should not come as a surprise, considering that the method focuses on a clear transfer of information in every step. When used in software development, each new step includes a new group of people.

While that might not be the case in all companies, the information should still be documented throughout the lifecycle of the product. Whether you are experiencing unexpected changes in personnel or simply passing projects off at every step, waterfall always prioritizes accessible information.

This helps make new additions to the team up to date quickly if necessary. If you want to maximize your benefits from this waterfall characteristic, you should stay organized with the right process.

Waterfall prioritizes a clean and defined set of steps, unlike other SDLC methodologies. It has a structure that is both simple and straightforward. Teams are required to finish an entire step first before transitioning into the next one. This means if there are challenges to completion, they are identified and solved immediately.

Comparing the Waterfall methodology vs Agile which follows an incremental approach whereas the Waterfall is a sequential design process. Agile allows changes in project development requirement whereas Waterfall has no scope of changing the requirements once the project development starts.
