What is Prototype Model

What is prototype model ?

Prototype Model :

• A prototype Model suggest that before carrying out the development of the actual software, a working Prototype of the System should be build.
• Prototype Is Working Model of a software with some limited functionality
•  Prototype  is used to allow the users evaluate the developer proposal and try them out before impotent.

Work of prototype model : 

• Initial Requirement :   In this stage we collect the all Requirement from the Client and make a design .
• Design :In this stage we have Request for the project to as per requirement we construct a design .
• Prototype :  In this stage we make a prototype as per requirement and show the client if client says OK then we move development phase other wise we need to update and redesign prototype .
• Customer Evaluation :  Customer give a Requirement list . we check as per requirement the project is done or not . if done then OK else tell to redesign the prototype .
• Review and Update : if prototype is not done as per customer requirement then we have to update the design .
• Development : When Prototype selected then we go development phase and as per requirement  and prototype we develop our project . Here all software divide small Module .
• Testing : In this phase we test the project we use White box testing and  black box testing .
• Maintenance :  This is the Final Phase of the Model in this phase when complete all testing we Handover the project to Client . if Need little update or modification we do in this phase .

Advantage of Prototype Model :

• can be used to test every detail of the final product before the product build
• Result is higher user satisfaction .
• user better describe this requirement .
• it save time and money .
• not very complicated .

Disadvantage of Prototype Model : 

• if the client is not satisfied  , we need re design the prototype until the client is not satisfied .
• the resulting system is not harder to maintain .
• Need more Experience team member .
