prototyping

Information system applications can be best achieved with the help of the Prototyping which helps the developer to create a working model. Prototyping helps to give an idea about the system but it doesn’t contain all the features or it doesn’t perform the necessary functions which are needed for the final system. Stages in the prototyping like the customer evaluations suggest the necessary additions and modifications which are to be made in the system to make it more useful for the users. Prototyping process is said to be an iterative process as it helps to fulfill the needs of the users and customers. As compared with the other models or process Prototyping process can be implemented with less amount of capital. It can be made up using actual paper works or some computer software’s which generate the necessary reports. Following are the steps in Prototyping

Requirement gathering and refinement

The objective and the plans are laid by the customer and the analyst/ developer. They identify the requirements for making the system more feasible.

Develop working model

The user and the developer identify the data which will be needed for the system. They also predict the output that the system will yield. This helps the management to estimate the overall costs for the productions and how profitable the system will be to the organization. In this phase a rough idea of the cost is given by the developer and the tools that will be required for the development of system.

Customer Evaluation

The user actually works on the prototypes in order to evaluate its operations and features. According to the working of the system the user gives positive or negative feedback to the developer.

Review prototype

In this phase a feedback from the user’s side is obtained from users and the required suggestions if any are made by the users. The developer must understand the needs of the uses properly and likewise the necessary modifications.

The prototyping approach is best suited for the smaller organizations where capital is an issue.
