In this article, we will explore rapid application development (RAD) in detail. The final stage of RAD involves deploying the built system into a live production environment. The deployment phase involves intensive scale testing, technical documentation, issue tracking, final customizations, and system simulation. Teams also spend time debugging the app and running final updates and maintenance tasks before going live. Data translation, testing, and the switchover to the new system, as well as user training, are all part of this stage.
If you’ve got a product that caters to a large audience, then it makes sense to use rapid application development. Kissflow, for instance, uses RAD methodology for its no-code development for citizen developers. Rapid Application Development methodology is popular because it helps small teams create software that can quickly adapt to market and customer requirements. RAD methodology is difficult to implement with multiple teams and a large number of developers.

Engineers and developers work tirelessly to flesh out a working system from a working model. Feedback and reviews are crucial at this stage and most bugs, issues, and alterations are addressed during this stage. This stage can be particularly long, especially in cases where clients change directions or feedback is intensive. To start this RAD example, gather all the people who know the process best, starting with the procurement team.
In the old days, custom software was designed for huge corporations with deep pockets. Another difference to note is that, in RAD methodology, the primary method of calculating progress is to deliver functional prototypes as frequently as possible. But in Agile, progress is achieved by delivering a high-quality product at the time of delivery. A timeline of 2–3 months is ideal for RAD, and most importantly, the technical risk should be low.

Kissflow's rapid application development platform is a no-code work platform that lets anyone develop their own automated process in a matter of minutes instead of days or weeks. Kissflow can be used by a single person to work on developing an application. Initially, rapid application development took the shape of the Spiral model , where one or more development models were used to work on a particular project. A major challenge with the waterfall model is that once the product moves into the testing phase, the tester cannot go back to reiterate and make changes to the core functions and features.
RAD was born out of frustration with the waterfall software design approach which too often resulted in products that were out of date or inefficient by the time they were actually released. The term was inspired by James Martin, who worked with colleagues to develop a new method called Rapid Iterative Production Prototyping (RIPP). In 1991, this approach became the premise of the book Rapid Application Development. Rapid Application Development (RAD) can reduce your risk and delivery time while allowing you to engage more with your customers and business users during software development.
RAD Is Faster
As a data communications company offering telecom access solutions, RAD strives to deliver best-of-breed telecom devices for communications service providers and critical infrastructure. Whether for business services, mobile xHaul or secure IIoT, RAD supports customers through the entire project lifecycle, from design to deployment. When it is necessary to design a system that can be divided into smaller units within two to three months.
James Martin first developed the development approach in the 1980s when he was working with IBM. In 1991, he formally introduced it as a concept, which was built on the work of people like Barry Boehm. As a BPM suite, it offers solutions that are more drag-and-drop than sit-and-code. This makes it incredibly convenient for developers and users who aren’t familiar with coding. Rapid application development is well-suited for small and medium-sized projects where the application is intended to be delivered incrementally.
Clients will also need to be proactive in making trajectory-based decisions. With the boom of smartphones and cloud services, there’s been an exponential increase in the requirement for good methodologies to make software quickly and efficiently. Because of the similarities between the two, rapid methodology and Agile development have often been thought of as one and the same. The requirement of a high level of commitment from all stakeholders is one of the pitfalls of using RAD for small projects and products.
- Radzen is a low-code solution that creates Blazor and Angular web applications connected to local databases or RESTful services.
- If you have extremely talented developers, they may be able to build these apps from scratch.
- If you prefer using multiple systems for other parts of your work, OutSystems will easily integrate with those tools to give you an easier development experience.
- The goal of RWAD is to reduce the time and cost of developing web applications while still producing high-quality, functional software.
- Additionally, RAD requires a team of skilled developers and engineers who can work at pace.
In addition, Kissflow's platform allows users to automate business processes using RAD principles, enabling the creation of automated apps at a rapid pace, with no coding required in some cases. Nowadays, companies around the world embrace agile frameworks and methodologies. But before agile could run, RAD walked onto the scene first to emphasize the need for speed and user feedback in software development — which, not coincidentally, are among the core values and principles of agile. RAD is the best approach to develop prototypes swiftly for testing software functionalities without worrying about any effects on the end product. Businesses opt RAD approach as it requires little focus on the planning phase while enabling the team to design, review, and iterate features and functionalities quickly.

Stakeholder feedback is incorporated and the application is tested extensively before pushing it to a live environment. A real, working application should be constructed within a very short amount of time and changes need to be implemented instantly. Anyone working on a RAD project should have an extremely clear vision on what the application rad web development should do and what problem it is trying to solve. You can assign roles and responsibilities to each and every user, with permissions so that every person only has the data that they need access to—nothing more. When growth and scalability are critical product considerations, you’ll generally want to choose a more versatile framework than RAD.
If there are any changes, you can make them quickly and–crucially–without breaking the whole thing. During this step, stakeholders sit together to define and finalize project requirements such as project goals, expectations, timelines, and budget. When you have clearly defined and scoped out each aspect of the project's requirements, you can seek management approvals. In addition to this, it also allows seamless integration with third-party tools of your choosing. Appian is scalable according to your needs, whether you’re a company with 10 users or 10,000 users.
Benefits of Rapid Application Development (RAD) model
This technique allows programmers to change the model as they go until they find a design that they like. The team gathers all available feedback, and it is at this point those original needs are subject to alteration. Something that looked good on paper may appear very different in practice. With this information in hand, programmers return to the prototype stage until the users are happy. If you’re thinking of automating and streamlining your workplace for rapid application development, give Kissflow Software a shot.
