Prototyping is used in the design phase of the SDLC, whenever a new system model is built; particularly prototypes are used to give the end-user a convenience for manipulation. Prototypes are used within organizations as a significant tool for Systems Analysis and Design (SAD). Prototypes act as tools that are determined to evaluate and test the working models that can be used on the project as two common approaches ‘object oriented’ and ‘life cycle’ approach, both with a common aim of producing a successful and error-free information system.
Beneficial for small and large application developments, prototyping can easily provide an organization the opportunity to test the application several times before implementing it. In case a new project is assigned to a business, prototyping makes things easier for a business owner to analyze his product through testing and making measurement and control instruments user-friendly in continuous processes. Examples include systems of computer-aided design production and manufacturing, development in the transport sectors, robotics enhancements in metal manufacture, and specialized applications software in a whole range of industries.
A prototype is the full and final version of the estimate of a type that exhibits the essential features by implementing a prototype first, the analyst can show the users inputs, intermediary stages, and outputs from the system. A prototype is not limited to diagrammatic explanations, which can later tend to be looked at as abstract things, or technically oriented documentation, which may not be understood by the user, but the actual representation of the system on the screen with the relevant outputs. Prototyping is an approach used in the SDLC process and can be implemented by data dictionaries, fourth-generation systems, CASE tools, and workbenches of various kinds. Prototyping is used in an IS project whenever the project is supposed to proceed according to a well-defined plan or method, possibly supplemented with backtracking, whereas the process model emphasizes that continuous learning during the development process requires frequent re-planning of the development process.
