At the same time, web applications use the latest programming techniques, gather inputs from a variety of sources and offer many new functionalities, features and modules (p. 16-17). Hence, the same approach of software engineering cannot be applied to them. Prototyping model is a part of the prescriptive process model and is a part of the evolutionary process model. In prototyping, the customer defines a general set of objectives for functions and features. The developer then uses these requirements as the basis, identifies the requirements and then creates a prototype model for the software that is further refined until the final product is ready (p. 43-44). The prototype model is used to develop applications used by a organizations in different sectors namely, banking, insurance, manufacturing and retail. As an example, banking applications have requirements such as registering the customer, assigning an account number for each customer and tracking their account related activities.
