Thanks. We'll let you know when a new response is added.

It is the development approach of activities during software development the creation of prototypes. The prototyping approach in SDPM is mainly depends on :

1. Identify basic requirements: Determine basic requirements including the input and output information desired. Details, such as security, can typically be ignored.

2. Develop Initial Prototype: The initial prototype is developed that includes only user interfaces.

3. Review: The customers, including end-users, examine the prototype and provide feedback on additions or changes.

4. Revise and Enhance the Prototype: Using the feedback both the specifications and the prototype can be improved.

5. Not a standalone, complete development methodology approach, but rather an approach to handling selected portions of a larger, more traditional development methodology.

6. Attempts to reduce inherent project risk by breaking a project into smaller segments and providing more ease-of-change during the development process.

7. User is involved throughout the development process, which increases the likelihood of user acceptance of the final implementation.

8. Small-scale mock-ups of the system are developed following an iterative modification
process until the prototype evolves to meet the users’ requirements.

9. While most prototypes are developed with the expectation that they will be discarded, it is possible in some cases to evolve from prototype to working system.

10. A basic understanding of the fundamental business problem is necessary to avoid solving the wrong problem.
