What this article shares with you is about the benefits of rapid application development of the RAD model. The editor feels that it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Rapid application development (RAD) is a development model that emphasizes rapid prototyping (usually instead of written design specifications) and iterative development. The process is no longer focused on planning, but more on adaptive methods.

This model is an ideal choice for customers who want to find results in a short period of time. It also helps to improve the functional requirements of the application.

Rapid application development process

The rapid application development model is divided into four phases:

1) Planning

2) prototype making

3) Development

4) delivery

5) Planning

Although planning is not the main focus of this process, it does help to outline its requirements. However, instead of going into the details at the beginning, you capture a wide range of requirements during the planning phase. Spend a lot of time understanding the requirements, the core functions required, and any other features.

At this stage, developers also provide their opinions and concepts based on their experience so that you can get the maximum return on your investment.

In short, the planning phase is mainly used to ensure that your needs are clear and that there is no functional gap.

Prototype making

One of the main advantages of the RAD model is that it starts with a well-functioning prototype. This allows you to view and use the product to understand how it works without having to try to visualize it with paper text.

At DCSL, we set up a backlog of orders with the prototype. In the backlog as a blueprint for your software applications. It is used to identify each area of the application and explain what it contains and how each aspect works in detail.

Both prototypes and to-dos can provide you with a detailed description of the final product and its functions.

Course of development

Once you are satisfied with the prototype and backlog, the development phase begins.

Waterloo rapid application development toolset

To quickly deliver prototypes and final products to our customers, we use Waterloo, our internally developed RAD toolset.

Waterloo consists of a number of components designed to speed up the development of common functions in software systems. Its three main components are:

1) Project template

2) scaffolding engine

3) General Library

Project templates help provide a structured starting point for any new application.

Scaffolding engine enables developers to quickly generate universal screens and automatically generate generic or repetitive CRUD (create, read, update, delete) code.

Common libraries provide general functions such as messaging, authentication, logging, file management, and search.

The toolset also allows reusable code to help developers deliver prototypes and products to customers in the shortest possible time.

Delivery

The final stage of the RAD process is when the product is delivered. If you use a fixed price plan, it may be the final product, or you can evaluate and test iterations.

What are the benefits of a rapid application development approach?

Speed

As the name implies, delivery speed is an important feature of RAD. The model relies on prototypes that are quickly delivered to customers. This means that you will get a product working model that can be used in the shortest possible time.

Pay attention to detail

In some cases, a software development project may fail due to a lack of planning. Developers are excited to start development, while customers are unaware of the complexity of the project. This usually means that potential problems are ignored.

In the RAD approach, the initial plan may not be very detailed, but it will involve an understanding of the broad requirements of the project. Even if more detailed details are not discussed, they can be added during prototyping and iterative development (when the product can be used and problems are identified).

Easy visualization

It is often difficult for customers to visualize the final product and the problems it will solve. Through the RAD method, you can get a prototype, which not only makes it easier for you to see the appearance of the product, but also makes it easier to understand its functionality. In this way, there are no assumptions.

Low cost

RAD assists with tools that allow reuse of code, pre-developed libraries and templates. As a result, many time-consuming coding tasks have been completed, which means that developers can focus on custom features. Because developers do not need to spend much time building applications, the cost is lower.

In addition, because this basic code has been pre-tested and validated, there is less bug to fix after development. Finally, because of the prototype, it is easier to check that the application has all the functionality you need without making future changes, which will cost you more.

Quality

As you can see, a pre-tested code base can help you get software products free of errors and code errors. This means that RAD can provide you with high-quality software applications with lower cost and better support for a long time.

In addition, because you can interact with the prototype during its development, you have a clearer understanding of what the product provides and what is missing. Constant feedback is part of the RAD approach as well as agile methods. This means that you can test your product to see if it meets all the requirements of your business.

Any missing functionality or errors can be reported to developers so that they can fix them in the next iteration.

Risk control

Through rapid application development, you can develop low-cost, high-quality prototypes in a short time. As a result, you can see the appearance of the final software application early in the process.

The prototype can then pass the usability test, so you can check that it works as needed.

Therefore, you do not risk getting a final product that does not meet your expectations.

Conclusion

If time and money are limited, rapid application development may be a great way to develop software. It offers many benefits, including high-quality products that meet your requirements.

These are the benefits of rapid application development of the RAD model, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
