Why the HokuApps RAD Model Fares Better than Traditional Models

what is rapid application development

What is “Rapid Application Development”?

  • Rapid Application Development, or the RAD, is a model used for developing software applications.
  • The RAD model was developed by James Martin in 1991 and quickly replaced traditional software development methods and approaches that had a linear or “waterfall” development process.
  • This implies that the stages of app development using the RAD model enables each stage to be worked upon in simultaneous continuity as and when additions and other changes need to be incorporated.
  • As very little coding is required, it accommodates the participation of team members who understand the business oriented goals that the app is being built to achieve.
the five essential stages of the rad model

The Five Essential Stages of the RAD Model

  • Stage 1: Business Modeling
  • This stage is all about the gathering of business related data.
  • This includes everything from insightful knowledge of the internal workings of an enterprise to insights gained from systematic analysis of big data.
  • Stage 2: Data Modeling
  • This stage involves analyzing all the information gathered during business modeling, and sorted into logical segments with descriptive labels in a way that will further the particular business goals.
  • How these different data segments relate to each other are also established in this stage.
stage 3 process modeling this stage involves

Stage 3: Process Modeling

  • This stage involves rendering the classified data usable to the app production process.
  • The data gathered and classified in the two previous stages are now altered and optimized to use, and defined further.
  • Stage 4: Application Generation
  • This is the stage in which all the data models created so far are coded, and the system to develop the prototype of the actual app is built.
  • The data models are transformed into prototypes in this phase.
testing and turnover

Testing and “Turnover”

  • In this stage, every data model is tested to ensure that components are well defined and can even be interchanged in order to streamline the end product, which is the app.
  • Usually, by the time that this stage is reached, all the components have been tested out already, so no major disruptions are expected to occur in the prototype.
the differences between the rad model and sdlc

The Differences between the RAD Model and SDLC

  • SDLC - Software Development Life Cycle - there is a whole lot of planning and analysis that takes place before the process of coding is initiated.
  • This is quite inconvenient as the process as any semblance of a solid component only materializes after a long time.
  • Any modifications to the component after that then becomes tedious, and at times, even impossible, in the later stages of development.
  • In comparison, the RAD model is far more effective, as what can be called a “working model”, comes into the picture from the very beginning.
  • The prototype can be reviewed, altered, and customized right away. Throughout the development lifecycle of the app development process using the RAD model, changes can be accommodated as per requirement.
the rad model in practice

The RAD Model in Practice

When the system can be divided and worked upon in modules and then distributed.

When there are adequate resources dedicated to modeling.

When the budget for the process accommodates automated code generation.

When there is clarity as to which development model is most suitable: the RAD model or the SDLC model.

When changes are expected to be made to the working model as per business requirement.

when should the rad model be implemented

When Should the RAD Model be Implemented

A RAD model is very useful when a product needs to be delivered in a short period of time.

It is also a good solution for when the app development process needs several changes to be made to the working model.

As the RAD model is a collaborative process, adequate resources from both the IT department and the personnel who understand the business processes of the organization must be available for their valuable inputs throughout the project lifecycle.

The resources with different types of expertise must communicate effectively to get their points across to each other.

As the RAD model is a process in which the customer’s requirements are factored in at all stages, the process is a highly interactive one as well.

why you must give hokuapps a shot

Why You Must Give HokuApps a Shot

  • HokuApps offers a platform on which to develop apps following the RAD model.
  • The best part is that HokuApps platform evolves with market trends and allows you to adapt your app to the latest customer demands and tailor the app according to the customer’s needs.
  • The HokuApps RAD model also helps developers to build a successive series of apps, all of which require minimal coding.
  • HokuApps offers a free trial period of three weeks during which your team can use the rapid application development platform before making the final purchase.
