The document discusses the Rapid Application Development (RAD) model, an incremental development approach focusing on parallel creation of system components aimed at obtaining user feedback early. It outlines the phases of the RAD model, including business modeling, data modeling, and application generation, and lists advantages such as reduced development time and increased user involvement. However, it also notes drawbacks, including dependency on skilled teams and significant financial investment in modeling processes.

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.
