RAD Model

RAD MODEL:


  • Rapid Application Development Model.
  • It is a type of Incremental Model.
  • It is high speed adaptation of Waterfall model.
  • In it projects are developed in component as mini projects.
  • Than mini projects are assembled in a single project.
  • It takes very short period of time to construct a project.
  • Customers can give feedback easily on mini projects as well as on complete project.


Following is the illustration of RAD Model:

Advantages of RAD Model:

  • Increases re-usability of components.
  • Less development time.
  • Quick initial responses.
  • Encourages customer feedback's.
  • Involvement of end users from very beginning solves lot of development issues.

Disadvantages of RAD Model:

  • Projects which can be developed into mini projects/components can use RAD Model.
  • Requires strong and skilled developers team.
  • Cost is very high..

When to use RAD Model:

  • When there is need to develop system within short period of time (2-3 months).
  • When there is high availability of developers.
  • When budget is high enough to afford the development cost.




1. RAD Model has
a) 5 phases
b) 2 phase
c) 3 phases
d) 6 phases
View Answer
Answer:a Explanation: RAD Model consists of five phases namely:Business modeling,Data modeling,Process modeling,Application generation and Testing & Turnover.


2. What is the major drawback of using RAD Model?
a) Highly specialized & skilled developers/designers are required.
b) Increases re-usability of components.
c) Encourages customer/client feedback.
d) Both a & c.
View Answer
Answer:d Explanation: The client may create an unrealistic product vision leading a team to over or under-develop functionality.Also, the specialized & skilled developers are not easily available.

5. RAD is a linear sequential software development process model. RAD
is an acronym for ?
a. Rapid Action Development
b. Rapid Application Development
c. Rough Application Development
d. Rough Action Development

View Answer
Answer:b
Rapid Application Development. The term was inspired by James Martin, who worked with colleagues to develop a new method called Rapid Iterative Production Prototyping (RIPP). In 1991, this approach became the premise of the book Rapid Application Development.p>
