9. Explain the rapid prototyping techniques.

6 marks | Asked in 2068(II)

Rapid prototyping involves creating a working model of various parts of the system at a very early stage, after a relatively short investigation. The model then becomes the starting point from which user can re-examine their expectations and clarify their requirements. When this goal has been achieved, the prototype model is thrown away and the system is formally developed based on the identified requirements.

Rapid prototyping techniques

Various techniques may be used for rapid development:

1. Using high level language:

  • High level language include many powerful data management facilities. 
  • Using high level language we can create prototype with very little programming effort.
  • Some languages offer excellent UI development facilities.

2. Reuse component:

The time need to develop a prototype can be reduced if many parts of the systems can be reused rather than designed and implemented. The reusable components may also be used in the final system thus reducing its development cost.

3. Ignore error handling:

In many system as much as one-half of the software is concerned with error handling. The time need to develop a prototype can be reduced If we ignore the error while designing prototype.

4. Omit features:

Omit features which are costly and takes large time to develop. So their omission make construct of prototype quicker.

5.Ignore functionality:

Only focus on establishing an acceptable user-interface.

6. Database programming language:

It includes a database query language, a screen generator, a report generator and a spreadsheet. These may be integrated with a CASE toolset. These are cost effective for small to medium sized business system.
