Using Rapid Application Development

Their mission is to work with businesses to deliver a project that meets client needs. Rapid application development is not an unfamiliar methodology for accomplishing this goal. Remember, rapid application development is by definition iterative. Because RAD doesn’t follow a straight and narrow procedure for making changes, the software development team can adjust for new requirements at any time.

The final phase gives the development team time to move components into a live production environment where all the necessary comprehensive testing or user training takes place. Rapid application development is a means to approaching the software development life cycle that encourages frequent prototype releases and iterative, continuous delivery. We already know that rapid application development is not a prescribed list of specific tools and processes. Agile and other adaptive approaches to software development have helped fill in some of the details over time, providing high-level RAD ideals with some foundational best practices that can be shared and scaled.

Components can be built and tested together sooner, leading to quicker mitigation of errors that wouldn’t show up until much later in a traditional waterfall SDLC. Unlike waterfall checkpoints, where stakeholders must wait on hand-offs from a previous phase before they can begin work, RAD emphasizes working continuously in parallel. Rather than gathering requirements once and then waiting for a finished product to find out if those requirements are met, rapid development moves as quickly as possible to design and build.

In the iterative process, all of the flaws and kinks are ironed out. The developer creates a model, the customer tests it, and then both parties meet to discuss what succeeded and what didn’t. The finished product is implemented and goes for launch in this phase. During this definition of rapid application development stage all the final changes are made, data conversion, testing, and changeover to the new system is done. RAD methodology can be an effective strategy for a number of different projects and teams, but you should consider the following key factors before you implement.

It focuses on the development level as opposed to the broad vision. Agile is a philosophy, arguing that the power of software to enable tighter release cycles makes Waterfall obsolete. From apps that save lives to those that process loans in a few clicks, you can use OutSystems to bring your visions to life. Managing an application portfolio effectively is possible with robust application development and maintenance.

Data translation, testing, and the switchover to the new system, as well as user training, are all part of this stage. Once the product has been authorized, programmers apply the finishing touches such as testing, conversion, interface, or user training. Once the product has been adequately evaluated for criteria such as stability and lifespan, it is ready for delivery. It’s time to finish developing and testing the RAD system so it can go into production.

  • It also helps your team keep clients in the loop, as this phase isn’t about the developers “going off on their own” — all stakeholders should still be able to have their voices heard.
  • A user-friendly dashboard is the best way to make non-technical stakeholders into active participants.
  • It can also lead to identifying opportunities for re-using code and objects across the application since developers are building pieces of the system independently but simultaneously.
  • A good dashboard for requirements planning saves an enormous amount of hassle in the long run.
  • As you iterate several prototypes in parallel, don’t be afraid to borrow parts from one to improve another.

RAD frameworks help developers save time by organizing and streamlining their work. Frameworks save time by eliminating the need to create libraries and methods from scratch. Got a pool of users who can consistently provide reliable feedback on your prototypes?

Rapid application development (RAD)

This occurs through a set of automations that eliminate the need for manual testing. Not every startup can afford to wait between 6-12 months to launch their application. Rapid application development is an effective solution for these cases.

In turn, RAD emphasizes the parts of software development that are vital to the success of a software product, namely its usability in the long-term for the end-users it’s built for. Through trial and error, software developers have discovered that speed and feedback are often the most important factors that go into a software development project. Rapid application development has four phases or components that constitute the overarching framework—requirement gathering, rapid prototyping, construction, and deployment. It’s no secret that no-code/low-code platforms are quickly becoming the future of software development. According to Gartner, no-code/low-code application development will be responsible for more than 65% of application development activity by 2024, and the g… There are a lot of excellent object-oriented application building platforms on the market that allow you to build basic SaaS applications.

How does Rapid Application Development work

And beyond development, you need a design and product team willing and able to rapidly context-switch between ideation and assimilation (processing feedback from clients and end-users). The RAD model is a good way to improve collaboration between users, customers, and developers at all stages of the development process. Involving users is particularly useful in scenarios where user requirements are uncertain.

The Future of Application Development

The RAD methodology is best for small, flexible, and self-organizing teams who interact closely with their client-base. Although RAD is not best for every team, the right team will be all the more grateful for the improvements that rapid development engenders. This approach, taking elements from the work of Barry Boehm, is business-oriented and asserts that reactive development is a more efficient resolve than defining specifications. Initially, Barry Boehm, James Martin, and a number of others saw that software was not limited to traditional methods of engineering. This also includes your customers, internal or external, because their participation is critical. Within the RAD environment, each element within the software is compartmentalised, hence making it easily modified autonomously as requirements evolve/change.

In the slow, methodical software development methods of olde, receiving useful and concrete user feedback has been inherently difficult, costly, and time consuming. Long meetings and phone calls, and even longer design docs, were a necessary evil to lay out even the most basic concrete plans of proper software design. With typical waterfall methods, rudimentary user feedback was often many months if not years in the future, after all planning and most development had taken place.

Phases of Rapid Application Development Methodology

We use tools such as RAD recurring prototyping and DevOps procedures. The key to rapid application development is to reach objectives fast while maintaining quality. Our team at NCube can help you set up a development team that will utilize the RAD methodology to develop software under your leadership. Let us know about your project in the contact form and we will help you choose the best strategy. RAD suggests that there will be lots of discussions about functionality, testing the prototypes, updates, and ongoing feedback. If the user does not have enough motivation for this, trying standard models will make more sense.

Today, the use of RAD is quickly becoming a necessity, thanks to the volatile market conditions and competitive marketplace. This is the meat and potatoes of the RAD methodology—and what sets it apart from other project management strategies. During this phase, clients work hand in hand with developers to ensure their needs are being met at every step in the design process. It’s almost like customizable software development where the users can test each prototype of the product, at each stage, to ensure it meets their expectations.

How does Rapid Application Development work

Rather than working deep in siloes and only interacting during a hand-off, teams can work collaboratively to design, build, and fix code inside a working prototype. It can also lead to identifying opportunities for re-using code and objects across the application since developers are building pieces of the system independently but simultaneously. Another peculiarity is the constant user feedback, something that is hard to achieve with other models. In fact, in most models, user feedback takes the backseat until the product is finalized. Conversely, the RAD model encourages and prioritizes customer feedback.

Define Requirements

Increased velocity also means your software application will hit the market quicker, guaranteeing a better return on investment than otherwise. You need to make sure you can balance a big-picture perspective alongside specialized skills. Even if money is saved over the entire SDLC, costs can be a barrier to RAD adoption. Customers – RAD excels where customers can be engaged early and often. Otherwise, meaningful iteration gets much harder, and a shift to RAD is less meaningful.

Rapid Application Development Disadvantages

With RAD, projects are more likely to finish on time and to the client’s satisfaction upon delivery. Cost In rapid application development, developers build the exact systems the client requires, and nothing more. In waterfall, IT risks building and fleshing out complex feature sets that the client may choose to gut from the final product. The time spent building zombie features can never be recovered, and that means the budget spent on them is lost. Developer Satisfaction In the traditional waterfall approach, developers work in silos devoid of feedback and positive affirmation for a product well-made. And when they finally get the opportunity to present their work to the client, the client may not roll out the red carpet for them.

The advantages of RAD include it’s ability to engender speed, flexibility, and customer-centric design. While it still remains the champion, a lot has changed in 20 years. Come to them with a requirement for a software that would interface with their customers, one of which had over 35,000 employees, for procurement, invoicing, and payment. You may not have heard of RAD, but you’ve probably heard of Agile. While RAD pre-dates formalized Agile thinking by about a decade, it’s become the most popular expression of Martin’s ideas. More meaningful iterations, where unknowns are tackled earlier, and learning can be better leveraged.

Now that we have looked at the four phases of Rapid Application Development, let’s explore if this model is a good fit for your project. You must have some non-mandatory requirements in each timebox, otherwise you don’t have enough flexibility. Good configuration control is also essential, since you have to be able to get back easily to an earlier working state.

This results in greater efficiency, faster development, and effective communication. More often than not, these prototypes are quickly made to work to showcase just the key features. This is normal, and the final product is only created during the finalization stage where the client and developer are in alignment with the final product. Instead of following a rigid set of requirements, developers create prototypes with different features and functions as fast as they can. These prototypes are then shown to the clients who decide what they like and what they don’t. It does mean that there needs to be project management above the silo level, ensuring teams are working in the same direction, even as they work at different ends of a particular application.

Once the project is scoped out, it’s time to jump right into development, building out the user design through various prototype iterations. In practice, the phases of rapid application development do not greatly differ from that of the waterfall model. The most noticeable distinction is that several steps of RAD are iterative, rather than sequential. The disadvantages of RAD usually aren’t enough to turn people away from enjoying the benefits of this methodology. But just in case, you should review the downfalls of employing rapid development for your software development process.
