Part 3  Implementation

 The prototyping approach is now ubiquitous since it reduces the risk of major design, 

functional or informational errors during the construction of the application that may be 

costly and  time‑  consuming to fix at a later stage in development.

 Today, the concept of prototyping has been extended across the whole life cycle for develop‑
