The prototypes may work for the current business need, but the future ones could be an entirely different ball game. If you plan on upgrading the software application often and using it for a growing team and/or business, go with a more formal and planned-out strategy. Start with a structured consulting process that includes business analysis and a heavier planning stage. RAD would only work for projects where the desired software product can be modularized and divided into independent components for teams to develop them in parallel. Communication with the customer and a number of well-prepared development teams are also essential. Since RAD processes focus on less planning and rapid prototyping to ensure business functionalities critical to the client, attention to non-functional requirements is often sidestepped.

What is Rapid Application Development

A prototype is a version of the product that mimics what that actual product will look like, and it can complete the same functions, which allows for a faster output of the created element. The RAD methodology is best for small, flexible, and self-organizing teams who interact closely with their client-base. The advantages of RAD include it’s ability to engender speed, flexibility, and customer-centric design.


    RAD Model: Design

    Groupwarefor communication among development members, and testing tools. Reduce the amount of time spent on development and increase the rate of delivery. The disadvantages of RAD involve its complexity, high demand of resources, and the need for developers to be heavily committed to the project at all times. Although RAD is not best for every team, the right team will be all the more grateful for the improvements that rapid development engenders.

    They can suggest alterations, changes, or even new ideas that can solve problems as they arise. This method gives developers the opportunity to tweak the model as they go until they reach a satisfactory design. Inapplicable to cheaper projects as cost of Modelling and automated code generation is very high.

    The data object sets defined in the Data Modelling phase are converted to establish the business information flow needed to achieve specific business objectives as per the business model. The process model for any changes or enhancements to the data object sets is defined in this phase. Process descriptions for adding, deleting, retrieving or modifying a data object are given.

    Phase 3: Rapid construction

    Advantage Description Speed In the traditional waterfall approach, developers were unlikely to go on vacation after delivering the product. Clients would invariably request changes ranging from interface to functionality after first delivery. 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.

    With rapid prototyping and continuous testing, the software development cycle takes a much shorter time than traditional models. In rapid application development, the speed of your team heavily depends on how fast the customer can provide feedback. Sometimes this gets stuck if many departments or business decision-makers are involved, halting an entire project.

    During this stage all the final changes are made, data conversion, testing, and changeover to the new system is done. In either case, there is a significant emphasis on early and continuous software delivery and room for changing requirements even in the later stages of development. As with any software development definition of rapid application development cycle, API security must be built in from the start. The RAD model is much more effective because it gives the customer a working model much sooner. The customer can quickly review the prototype, talk to investors in the meantime, showing them what the product would look like, and make changes much more easily.

    Developers face numerous struggles trying to perform traditional, end-to-end integration testing on microservices. When there is less time available for the creation of the product, such as within a span of a few days, the Rapid Application Development model is utilized. As long as the product being worked on can be easily divided into separate units, the RAD model can be implemented. This info is then combined into a useful description of how the data can be used when it is processed, and what is making this specific information successful for the industry. An evolution of this kind can make RAD difficult to deploy for smaller projects or when technical risk is high.

    How OutSystems Enables Rapid Application Development

    RAD enables clients to implement changes and does not require extensive pre-planning for concepts that the client might not fully grasp. RAD is a progressive development model that gives more importance to rapid prototyping and speedy feedback over a lengthy development and testing cycle. This model allows developers to make multiple iterations and updates to a software quickly, without the need to restart a development schedule from scratch every time.

    What is Rapid Application Development

    It also encourages customer involvement which is more than reasonable for contractors that want to satisfy the needs of a business rather than achieve their own unrelated goals. Rapid application development is only suitable for component-based and scalable systems. The development teams will not be able to work in parallel if the software components are interconnected. While these two models are often distinguished as separate methodologies, which prompts the comparison between them, they are, in fact, not that different in terms of underlying principles. Agile is more of a philosophy – a set of practices that favor adaptive planning, in-progress changes, customer involvement, and sustainable development, as per the agile manifesto. A couple of differences where RAD does not reflect the agile values is not offering any opinions on ways to enhance teamwork and adjust internal development.

    Rapid Application Development vs Other Development Models

    Since RAD treats the software as a pliable object, the requirement gathering phase needs to be detailed. It is very much likely that the requirements are going to change along the way. In order for rapid application development to work effectively, you must split up components of a product. Some projects just can’t be split into modules and worked on separately.

    • Or, they use third party components from trusted resources who adhere to industry best practices.
    • During the creation of a prototype for any product, to save time and money, it is essential to create one that can be reused for fast changes.
    • The rapid application development cycle begins with stakeholders defining a loose set of project requirements, equivalent to what would be accomplished during project scoping in traditional development cycles.
    • At Soliant Consulting, our team handles application development differently than described above.
    • Construction phase – focuses on program and application development task similar to the SDLC.
    • 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.

    Having the customer actively involved throughout the development cycle reduces the risk of non-conformance with user requirements, saving time and money. The Rapid Application Development Model was first proposed by IBM in the 1980s. The critical feature of this model is the use of powerful development tools and techniques. A software project can be implemented using this model if the project can be broken down into small modules wherein each module can be assigned independently to separate teams. Development of each module involves the various basic steps as in the waterfall model i.e analyzing, designing, coding, and then testing, etc. as shown in the figure.

    Requires a Specific Type of Project

    It is not meant for small-scale projects as in such cases, the cost of using automated tools and techniques may exceed the entire budget of the project. This is the main course of the RAD methodology—and what sets it apart from other project management strategies. By compressing parallel stages from the traditional Software Development Life Cycle , the cutover phase includes implementation, testing, integration, and maintenance. Business and IT stakeholders collaborate to quickly scope out a project—focusing on key objectives but allowing for flexibility during the prototyping sub-section of the User Design stage. It is important to know that the RAD model is only valid when there are plenty of knowledgeable developers and engineers on hand prepared to work on the progress of the product.

    What is Rapid Application Development

    During the Process Modeling stage, changes and optimizations can be done, and the sets of data can be further defined. Any descriptions for adding, removing, or changing the data objects are also created during this phase. Each phase of RAD focuses on delivering iterations in short intervals. Then the prototype for each iteration must meet the functionality of highest priority to the end-user — established from the latest collected feedback.

    However, for this approach to work, you will need talented software developers who can adjust quickly to change for the sake of innovation. Primarily for the reasons described above, rapid application development can be very demanding. Software development processes that use RAD can integrate constructive criticisms without going through the motions of a strict, linear organizational template.

    The product receives its finishing touches from activities such as testing and training that are carried out. After the product has been delivered to the consumer, it undergoes testing to see how long it will last and how stable it will remain. In order to maintain the adaptability of the project, the development process ensures that the boundaries of the requirements remain broad.

    When you should choose the RAD model

    The loop of constant work, testing, and feedback makes it almost impossible to launch a product that the client doesn’t love. The development process emphasizes short development windows to get an iteration of the product into the customer’s hands for review faster. This validates your work and vision more quickly, giving your development team a cyclical confidence boost. You can turn on a dime during your development process without going through several strategy reviews with clients, wasting their time and your developers’ time.

    The RAD model requires a frequent cycle of prototypes, and consequently, all stakeholders must be willing and able to commit to regular meetings to communicate and provide feedback frequently. The rapid application development approach focuses on creating applications faster with less attention on hardline planning and more on rapid prototyping and developing workable solutions. You can use low code development or no-code development platforms to minimize writing blocks of codes and create prototypes faster while reducing development time.

    Features are estimated used t-shirt sizing , and a rough three month plan is put together. From here, stories are put into a backlog where they can be estimated and prioritized. Work moves from backlog into two-week sprints once the designs for those features are finalized. At the end of each sprint, new features are deployed and the backlog is groomed and re-prioritized. In the planning stage, you’ll have designers, developers, and users come together to get a rough idea and understanding of what’s being created.

    Every business in today’s competitive landscape aims to provide new software and features to better serve its customers. The model should be chosen when the budget permits the use of automated tools and techniques required. It is also suitable for projects where requirements can be modularized and reusable components are also available for development. This model should be used for a system with known requirements and requiring a short development time. The team leader must work closely with the developers and customers to close the project in time. It can be used in the event that the budget is sufficiently large; it will be possible to hire designers.
