The Rapid application development model is a model for software development that stresses a short development cycle and uses an element-based construction technique. The Rapid application development model process allows a development team to construct a fully functional system in a short amount of time if the requirements are properly understood and specified and the project scope is limited.

What is the Rapid application development model?

  • Rapid application development is a software development process that prioritises rapid prototyping over extensive planning. A prototype is a working model that functions in the same way as a product component.
  • The functional modules are produced in parallel as prototypes in the RAD approach, then combined to create the whole product for faster delivery. Because little thorough planning is done ahead of time, it is easier to accommodate modifications into the development process.
  • Small teams of developers, domain experts, client representatives, and other IT resources work progressively on their component or prototype in RAD projects, which follow an iterative and incremental methodology.
  • The most crucial part of this model's success is ensuring that the prototypes created are reusable.

Different Phases of Rapid application development model

  1. Business Modeling: By addressing questions such as what data drives the business process, what data is generated, who generates it, where does the information go, who processes it, and so on, the information flow among business operations may be described in Business Modelling.
  2. Data Modelling: The information gathered during business modeling is refined into a set of data objects (entities) that are required to run the business. The attributes (characteristics of each entity) are defined, as well as the relationship between these data items (entities).
  3. Process Modeling: The data objects defined during the data modeling phase are transformed to provide the data flow required to operate a business function. For adding, changing, removing, or retrieving a data object, processing descriptions are written.
  4. Application Generation: Automated tools are used to make software development easier; they even employ 4th GL approaches.
  5. Testing and Turnover: Because RAD emphasizes reuse, many of the programming components have already been tested. This cuts down on overall testing time. However, the new part must be thoroughly tested, as must all interfaces.

Use of Rapid application development model

  • When an application needs to be produced must in short span of time (2-4 months)
  • When the specifications and requirements are known from before
  • When the user is involved throughout the entire life cycle
  • When there is less technical danger
  • When it's compulsory to build a system that can be modularized in two to three months

Pros, and cons of Rapid application development model

Pros Cons
It sped up the development process. User participation was required. Which can be hectic some time
Changes are adaptable in this model. RAD is incompatible with all applications.
Progress can be measured. We can't use the RAD paradigm for smaller projects.
Customer feedback is available during the early stages of the project. High-skilled experts are required to employ powerful and efficient tools.
It allows features to be reused more often. High dependency on Modelling skills.

  1. When Not To Use (Rapid Application Development) Rapid application development model?
    When stakeholders believe that implementing RAD will save them a lot of money or When stakeholders refuse to compromise on quality and refuse to let secondary requirements be 'timeboxed' out of the development cycle.
  2. What Are The Steps May Include In Rapid application development model?
    Creating Design and Building Prototypes are the most important steps in rad.
