Answer to Question 2

Unbalanced Architecture - Since the main thrust of prototyping is toward the user interface, developers tend to include more and more functionality in the outer layers of the information system, creating a distorted architecture.
The Illusion of Completeness - The real power of an application is under the hood (even if the application is a picture editor). For most users, however, the interface is what the application is all about. As a result, the clients might not understand why the developers insist that a lot more is to be done, especially if the prototype is of the throwaway variety.
Diminishing Changeability - Since prototyping can leave little trace of how the development evolved, modifying the application can resemble an archeological undertaking to piece together a lost civilization. If the Waterfall Model relies too much on documentation, prototyping can result in too little documentation or, more importantly, too little modeling.
