As the name implies, rapid application development (RAD) focuses on quick, iterative development for new software products. Rather than delivering a final product in its entirety one time like with other development methodologies, RAD projects deliver a product one iteration at a time in a shorter time frame.<\/p>\n
This is done through continuous feedback loops that inform future iterations, making RAD a very flexible and adaptable model. It\u2019s a popular development method for teams working on smaller projects who want to release a product quickly.<\/p>\n
This post will look at the RAD methodology and define its core steps, advantages and disadvantages, considerations for using the model, and how tools like monday dev are essential for working collaboratively in a fast-paced environment.<\/p>\nTry monday dev <\/a>\n"}]},{"main_heading":"What is rapid application development?","content_block":[{"acf_fc_layout":"text","content":" Rapid application development<\/a>, often abbreviated as RAD, refers to a software development methodology<\/a> that\u2019s adaptive and focused on the quick development of applications through multiple iterations and quick rounds of feedback.<\/p>\n Rather than an intensive planning phase, the RAD approach is concentrated on developing prototypes quickly and then collecting feedback before moving on to the next iteration.<\/p>\n<\/blockquote>\n The approach with RAD is that software development can benefit from frequent testing. Rather than spending development time and money on planning, teams that use the RAD model refine prototypes regularly until they\u2019re satisfied with a final product.<\/p>\n"}]},{"main_heading":"The history of rapid application development","content_block":[{"acf_fc_layout":"text","content":" Built as a response to other popularized development models in the 1970s and 1980s, such as the Waterfall method<\/span><\/a>, RAD\u2019s purpose was to focus less on planning and more on responding to feedback.<\/p>\n Software developers Barry Boehm and James Martin both contributed to developing this system in the 1980s at IBM. Essentially, Boehm and Martin saw software as something that could be worked on continuously rather than as a finite resource, leading to the creation of RAD.<\/p>\n"}]},{"main_heading":"Steps in rapid application development","content_block":[{"acf_fc_layout":"text","content":" The RAD method has four key steps, but the timeline for moving between one step and another can look different for every team depending on how many iterations a product goes through. Here\u2019s what the software development process<\/span><\/a> looks like for teams working with rapid web application development.<\/p>\n At this starting stage, the goal isn\u2019t to get a list of specifications from everyone and anyone involved in development but rather to have a guideline of essential project requirements. This might look like sitting with developers and key stakeholders to define a loose set of project requirements, including overall goals, anticipations, development costs, and a loose timeline. End users can also be consulted to make sure the final product aligns with their vision, but this stage of RAD shouldn\u2019t involve rigid or lengthy planning.<\/p>\n The essence of RAD is to move quickly, so right after project requirements are defined, the development team<\/a> goes into building a prototype that they can present to stakeholders and clients. Earlier stage prototypes are likely to only include one or a few components at a time so that stakeholders can focus on each individually. It\u2019s not uncommon for prototypes to be not fully functional as long as they demonstrate the feature being examined in a satisfactory way.<\/p>\n Once prototypes are viewed, the team collects feedback on all aspects of a product and its features, from functionality to design. It\u2019s possible for stakeholders or customers to change their minds and want to go in a different direction, in which case a new prototype is made to gather even more feedback. Essentially, the bulk of RAD is moving between the prototyping and feedback loop stages until everyone is satisfied with a result.<\/p>\n Once all feedback has been implemented and a prototype becomes more functional and includes most of the features it needs to operate properly, then the team focuses on deploying the software. Aside from developing a finished product, the deployment stage may also involve producing technical documentation<\/a>, bug tracking<\/a>, and testing the application before it\u2019s finally released.<\/p>\n"}]},{"main_heading":"Rapid application development advantages and disadvantages","content_block":[{"acf_fc_layout":"text","content":" There are many benefits to developing software quickly with an emphasis on feedback and prototyping.
