Everything on the planet, living and nonliving alike, has a daily cycle of existence. There is a time period between when something is conceived or created and when it dies or breaks. Its life cycle can be divided into stages that help us better understand how it progresses.

The traditional SDLC process is fundamentally based on the Waterfall approach, as it was the first and most established system to be used. Rapid Application Development is the most recent attempt to address the shortcomings of more established models. This way, we can compare the most recent strategy to the most established.

To consider the RAD model and the conventional SDLC, we need to understand how they work and their cycles.

The model of Rapid Application Development (RAD)

The RAD approach allows the mendix vs powerapps vs outsystems vs Wavemaker Low code pricing, customer to survey the application and provide feedback after each cycle that occurs during the time spent turning of events. This model is more viable, and end clients are generally satisfied with the end result, as they participate in all stages of development. The following are the phases of RAD:


Each task should begin with design. Each of the gatherings involved must sit down and define the task requirements. It is critical to discuss and consider the project’s schedule and financial plan investigation.

Constructing models

This is one of the critical distinctions between the RAD and conventional SDLC models. Here, useful models are created immediately based on the task’s requirements and the arranging stage’s conversations. These models are constructed in such a way that rapid changes can be made with little difficulty. Additionally, extensive testing and emphasis are performed to ensure that the product is bug-free.


The models of rapid web application development platform are now available for clients to use, audit and provide feedback on. They can recommend which features should be added or removed from the product based on their relevance to business processes. These methods are repeated until the client is completely satisfied with the product.


After all tests, modifications, and cycles are completed and the client is satisfied, the application is conveyed or finally introduced to the customer. Without a great deal of difficulty, updates and modifications can be made to the final product.

The conventional SDLC

This methodology ensures that the venture is planned out to the end and carried out methodically. Each stage of development should be completed before the next one begins. The advancement streams sequentially downhill, resembling a cascade, which is where the name comes from. The stages of this philosophy are as follows:


This initial stage SDLC rapid development methodology, entails thorough preparation of the task’s requirements. At this stage, the product’s purpose, capabilities, timeline, and financial plan are defined. Once this is accomplished, there is no going back.

Framework strategy

After the prerequisites are established, the stage of specialized planning begins. This stage converts the requirements into specific details. The experts assigned to this stage are responsible for the design, framework, and equipment requirements.


Once the planning stage is complete, the advancement stage begins. This is the location of all coding and testing.
