Implementing the prototype model for creating software has disadvantages. Since its being built out of concept, most of the models presented in the early stage are not complete. Usually they lack flaws that developers still need to work on them again and again. Since the prototype changes from time to time, it?s a nightmare to create a document for this software. There are many things that are removed, changed and added in a single update of the prototype and documenting each of them has been proven difficult.
There is also a great temptation for most developers to create a prototype and stick to it even though it has flaws. Since prototypes are not yet complete software programs, there is always a possibility of a designer flaw. When flawed software is implemented, it could mean losses of important resources.
Lastly, integration could be very difficult for a prototype model. This often happens when other programs are already stable. The prototype software is released and integrated to the company?s suite of software. But if there?s something wrong the prototype, changes are required not only with the software. It?s also possible that the stable software should be changed in order for them to be integrated properly.
