Every living and nonliving item on the planet has a life cycle. Between the time it is born or made and the time it dies or breaks, there is a period. Its life cycle can be divided into stages to assist us in better comprehend the development process.

Traditional SDLC primarily refers to the Waterfall approach, which was the first and most widely used methodology. The Rapid Application Development model is the most recent technique developed to address the drawbacks of previous methodologies like mendix vs powerapps vs outsystems vs Wavemaker Low code alternatives. As a result, we'll compare the newest and oldest methodologies.

To compare the RAD model to the old sdlc rapid application development platform, we must first understand how they work and what processes they follow.

The model of Rapid Application Development (RAD)

The client can evaluate the app and provide comments after each iteration in the development process using the RAD method. This methodology is more practical, and because end-users are involved in all stages of creation, they are usually satisfied with the final product. The stages of RAD are as follows:

Planning

Planning is required at the start of every undertaking. Everyone participating in the project must sit together and define the project's requirements. It is critical to discuss and develop a project timeline as well as a budget analysis.

Construction of prototypes

One of the most significant distinctions between the rapid application development platform and the regular SDLC is this.

Feedback

Customers are currently being given prototypes to try, review, and provide comments on. They can recommend which features should be added to the software and which should be deleted, based on their relevance to the business processes. These stages are repeated until the software is satisfactory to the customer.

Deployment

The program is deployed or finally provided to the client after all of the tests, revisions, and iterations have been completed and the customer is pleased. Updates and alterations to the final output can be made without much difficulty.

The typical SDLC (Software Development Life Cycle)

The project is planned out to the conclusion and implemented in a systematic manner using this method.

Planning

This is the first step, which entails meticulous planning of the project's requirements. The software's objective, functions, timetable, and budget are all specified at this point. There is no going back once this is completed.

Designing a system

The technical design process begins after the requirements have been written out. The criteria are transformed into technical specifications at this level. This phase's specialists are in charge of the architectural, system, and hardware needs.

Implementation

After the design phase is completed, the development phase begins. All of the coding and testing takes place here.

Installation and upkeep

Finally, the application is deployed after the build is completed. Following deployment, there is a warranty period and a maintenance phase. This phase will ensure that the app is available, that it has been improved, and that any bugs have been addressed.

When should you apply the RAD Methodology?

When a system must be built in a short amount of time (2-3 months)

When the specifications are known,

When the user is involved throughout the entire life cycle

When there is less technical danger

When it's necessary to build a system that can be modularized in two to three months

When a budget allows for the hiring of modelers as well as the purchase of automated code generating technologies,
