What is WaterFall Model?The Waterfall Model was the first Process Model to be introduced. It is very simple to understand and use. In a Waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. The waterfall model is the earliest SDLC approach that was used for software development. Show
In "The Waterfall" approach, the whole process of software development is divided into separate phases. The outcome of one phase acts as the input for the next phase sequentially. This means that any phase in the development process begins only if the previous phase is complete. The waterfall model is a sequential design process in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance. As the Waterfall Model illustrates the software development process in a linear sequential flow; hence it is also referred to as a Linear-Sequential Life Cycle Model. What are the different phases of the waterfall model?
All these phases are cascaded to each other in which progress is seen as flowing steadily downwards (like a waterfall) through the phases. The next phase is started only after the defined set of goals is achieved for the previous phase and it is signed off, so the name "Waterfall Model". What are the pros and cons of the waterfall methodology?Advantages of the Waterfall Model
Disadvantages of Waterfall Model
When to use the waterfall model?
What is the first step of the software development process?The first phase of software development starts with a requirements analysis. The company realized, that they could improve the efficiency of their quality management by using remote calls to an expert when a machine breaks down.
Which is a toy implementation of the system?A prototype is a toy implementation of the system.
Which model of SDLC is used for toy implementation?Before starting the actual development, a working prototype of the system was first built in the prototyping model. A prototype is a toy implementation of a system with limited functional capabilities, low reliability, and inefficient performance.
Which was the first model introduced for software development the model was the first model introduced for software development?Software Development Processes (SDLC Models)
The Waterfall Model was the first Process Model to be introduced. It is also referred to as a linear-sequential life cycle model.
