The RAD (Rapid Application Development)
development model is one of the types of
incremental model. The principle of parallel
creation of the system components and functions
underlies this model.

Each feature is like a separate subproject. It is
created in a certain time, sent, and implemented
into already working prototype. Thus, one may
immediately receive feedback from the end users
about the function itself and also about its work
directly. RAD model presupposes the presence of
the specified phases of derivation process of
software products.

• What Are the RAD Model Phases?
• Business modeling.
• Data modeling.
• Process modeling.
• Application generation.
• Testing (checking the web products or mobile
  application testing) and transfer and acceptance.

• What Are the Advantages of this Model?
• Less time will be required for developing the
  product.
• A possibility of the system components
  reusability is increased.
• A possibility of the quick initial views of the
  project.
• Direct user feedback.
• Integration from the very beginning of the
  development helps to avoid a majority of such
  types problems in future.

• What Are the Minuses of RAD Model?
• The outcome of the whole project depends on the
  level of commands which operate at each of the
  stages.
• RAD may be applied only to the systems which can
  be divided into modules.
• The experienced specialists (developers,
  designers, testers) with very good skills are
  required.
• A model strongly depends on the modeling skills.
• The modeling processes and automation require
  significant financial expenditures.
