Present Business Landscape Demanding Agile
Systems and Applications

• Conventional methods of software development like
  SDLC (System Development Life Cycle) had stable
  requirements and the development progress was
  often measurable. However, such processes were
  time-consuming and had the very little scope of
  user interaction.
• In a hyper-competitive environment where
  businesses are demanding the quick release of
  software applications and prototypes, developers
  cant help but reduce application development
  time while accelerating progress.
• Rapid Application Development (RAD) which rose to
  prominence a couple of decades ago, has
  successfully responded to the enterprise clarion
  call by delivering high-end applications with
  reduced time-to-market.

Embracing Leaner and Agile Processes with Rapid
Application Development

• The Rapid Application Development (RAD) model
  allows rapid application development and
  prototyping which ensures quick and error-free
  product delivery.
• Compared to other new age agile software
  development method, RAD stresses on rapid
  prototyping in order to eradicate even the
  smallest of the issues.
• Unlike the conventional waterfall model which was
  essentially based on requirements recording and
  planning, this model enables iterative
  development by taking user feedback into account.

Process Segmentation Phases of the RAD Model
Defining the Business Objectives In this phase,
the designers, developers, and testers identify
the potential opportunities and outcomes of a
project, along with the estimated
timeline. Analyzing Data Sets The next phase
involves a close analysis and review of the core
data assets in relation to the fundamental
business objectives. Building the
Prototypes After finalizing the project
requirements, opportunities, timeline, and
budget, the developer starts creating the
functional models of an application which are the
prototypes.
5
Evaluating User Feedback In this phase, the
users provide valuable feedback to the developers
who then analyzes the same to tweak and enhance
the prototypes, developing the best possible
final product. Testing In this phase, a
completed software application is operated under
different scenarios in order to make sure that
all the components work in tandem to accomplish
the systems end objective.

RAD The Differentiating Factors
Reduced Time-to-Market A RAD software application
enables a developer to segregate a project into
several modules. Every module is treated as a
single prototype which undergoes a separate phase
of testing. This systematic approach which keeps
testing at the heart of development significantly
reduces the application delivery time Effective
Market Analysis In this method, every completed
prototype can be evaluated by the end-user. Thus,
it becomes convenient for the developer to
closely analyze the prospect for further
enhancements and suggestions. Easy System
Integration RAD software development fosters easy
system integration by helping developers
assimilate all the modules during the early
phases of development.

Reusability of Application Components RAD ensures
easy reusability of application components with
rapid prototyping and modularity. User
Feedback-Oriented With RAD software development,
the developers have the added advantage of
analyzing user needs and sentiments while
implementing successive iterations within the
application.
