Many articles online are very informative, and many posts are very valuable, one thing I did learned from this many posts online about waterfall, is that the waterfall methodology, is indeed the godfather of all methodologies.
In today’s article we are going to talk about the waterfall methodology
In order to understand exactly how the waterfall methodology can help, any project of any size; we must first study this concept.
Without the waterfall methodology, developers wouldn’t think to try and understand other ways of developing software.
The other two software development life cycle methodologies, only exist because the waterfall methodology, still has flaws, and needs to be upgraded.
The software development methodology known as the waterfall, was the first process model to be introduced
Linear sequential life cycle model, is also another name for the waterfall methodology.
Many people use the waterfall method, because it is very easy and simple to use; because each of the phases in the waterfall method is completed, before going to the next phase.
In order to ensure that the successful development of a software is accomplished, a software development life cycle methodology must be used.
The waterfall approach, is divided into phases, and each phase do not overlap each other
These phases are:
- requirements gathering and analysis, which is the phase where all possible requirements, for the system, which will be develop, are captured.
- The system design is the second phase of the waterfall methodology, during this phase, the requirements specifications, from the first phase, are studied, and the hardware and system software are specified.
- Implementation is another phase of the waterfall methodology, during this phase the actual system is developed.
- The functionality of the system is also tested, before the system can move on to the next phase.
- Integration and testing, is the phase where the system is integrated into a development environment and tested, for any faults and failures.
- Deployment of system is another phase of the waterfall methodology, during this phase the product is deployed into the customer’s environment or is released into the market.
- Maintenance is another phase of the waterfall methodology, during this phase issues are fixed and new patches are released.
Better versions of the product is also released during this phase, and changes are also made to the customer’s environment.
The waterfall methodology allows departmentalization, and control, of the project.
Also schedules and deadlines can be set for each of the development stages of the product.
Although the waterfall methodology, has helped in many project, it does not allow much flexibility, for developers to be able to revise and reflect on the project, once they move to the next phase.
It is very difficult to go back, and change something with the product, once the application has reached the testing stage.
Companies that develop software have targeted goals, which are achieved in a fixed time frame.
In order for these companies to meet deadlines, and save costs, there must be strategies put in place.
The waterfall methodology does not only help companies develop software efficiently, but it also help developers, understand the product that they are developing, which is very important.
The software developers of a project, must understand, what that project entails, before they embark on that development journey.
