Requirement specification: Then, the above-analyzed requirements are documented in an SRS (software requirement specification ) document.

The primary role of this part is to eradicate incompleteness and inconsistencies related to software product development. Requirement gathering and analysis: First, all the information and need for the product development are gathered from the customer and processed for analysis.Not only this requirement is divided into two parts: 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 for the developed product, and the expected impact is studied, finalized, and documented. Specifically, we need to know and understand what we have to design, what we have to develop, its processes, what its functionality will be, etc. This phase deals with correcting 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. A primary prerequisite phase must be understood before starting the deep stages of knowledge. To get a more brief knowledge about the waterfall model, we need to understand its processes deeply 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 and then switching to another step, 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 stages of the design and development software cycle, which are as follows: Given below are the phases of the waterfall model: Programming models are used in the software development process cycle to plan the various stages of application development.
Royce in 1970, the waterfall model has been used widely in software development.
Since it was first published by Winston W.
The name ‘waterfall’ for this software development approach comes from the fact that it progresses systematically from one phase to another in a downward fashion. Its functionality is similar to the water flowing over the edge of a cliff. It emphasizes the logical progression of phase steps. According to this model, one should move to the next phase only after completing the previous phase’s testing, review, and verification. The history of the waterfall model dates back to 1970 when Winston W Royce introduced its first sample in an article.
