It results in designing models, schema, and business rules.

It also gives us the extension to decide the hardware or software requirements of the product which will be designed, developed, and captured in all phases. It provides input material to the product being made, and thus the upcoming product is studied, finalized, and marked. Thus the best solution is chosen.Īs specific by words, we need to know and understand what we have to design, what we have to develop, its processes, what will be its functionality, etc. This phase deals with the correction of the measures based on the analyzed benefits and drawbacks. It deals with the financial and technical aspects of the project requirements. It is about the feasibility study for the software product. There is a basic prerequisite phase that needs to be understood before starting the deep phases of knowledge. In order to get a more brief knowledge about the waterfall model, we need to understand all of its processes in deep with its work model.

So we can see that the waterfall model works hierarchy from top to bottom with one phase completed with full verifications then switching to another phase including phase processes like Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance. With the above infographics, we can understand that the waterfall model has a total of 7 phases of the design and development software cycle which are as follows : Now let’s talk about the phases of the waterfall model, which can be explained clearly through this demo infographic.
In the software development process cycle, programming models are used to plan the various stages of developing an application. Royce in 1970, the waterfall model has been used widely in the field of software development. Since the time it was first published by Winston W. This approach of software development has been given the name waterfall because it develops systematically from one phase to another in a downward fashion. Its functionality is similar to the water flows over the edge of the cliff. It emphasizes the logical progression of phase steps. Since then, the waterfall model state that one should switch to another phase only when the previous phases are completely tested, reviewed, and verified. To start with the history of the waterfall model, I would like to say that the first sample of the waterfall model was introduced in the year 1970 by Winston w Royce in an article.
