What is the Waterfall Model?
The acronym (SDLC) which stands for System Development Life Cycle was the earliest to be used for system development and it is called "The Waterfall Model". It can also be called as the "Linear-Sequential Life Cycle Model". The waterfall model illustrates software development process in a liner sequential flow. If the previous phase is completed, the development process shall begin. The progression in the waterfall model is seen as flowing gradually downwards through the phases as all these phases are arrange in a series or sequence to each other. The firstly phase should be finished before continuing to the following phase and the next phase will only start later at the specified allocated of goals

After the incorporate stage, the whole system is inspected and tested for any bugs and errors.
⦁ System Deployment − After the testing is done for functional and non-functional; the product is utilized in the client domain or dissimenate into the market.
⦁ Maintenance − There are some matter which arise in the customer domain. To resolve those problems, patches are dissemenate. Also to enhance the product, some updated variety are disclosed. Preservation is done to disperse these changes in the client domain.

What are the waterfall model’s advantages?
Waterfall Model Development allows for Departmentalization and control as it's advantages. Stage of development can set a schedule with deadlines and the product can progress through the growth procedure model stages accordingly.
Evolution moves from idea, through sketch, implementation, testing, installation, troubleshooting, and ends up at functioning and preservation. Each stages of development proceeds accordingly.
Major advantages of the Waterfall Model are as follows −
⦁ Easy to utulize and very well understood.
⦁ Easy to supervise due to the model being irreversible. Each stage has particular pre-requisite and a rechecking

The models are used in highly builded physical environments in which changes after the implementation are very expensive, if it is not difficult to deal with. Since it was first used in physical processes, one after another when software was not abundant, the waterfall model was only later modified for software development.

How are ideas presented in a waterfall model?
Since the waterfall model is very straightforward and understandable and it follows a step-by-step procedure, ideas are presented in a specific manner. The users of the model focus on only merely idea at a time and follow the waterfall model’s phases and will carry on to the next set of ideas for specified phases. As said in the other component of the research, the users of this model cannot proceed unless the stage in focus is finished.

Why is the waterfall model important?
The waterfall model is crucial because it can easily help the users and developers to understand the sequential procedure in development. Since it shows the processes in a cascaded format, each process is easily recognized by anyone who looks at its
