Frequently asked questions
What is the rapid application development life cycle?
The RAD life cycle starts with aligning stakeholders, developers, and users around key requirements—timeline, desired outcomes, expectations, and budget—before quickly building out prototypes to get a working version in front of stakeholders for feedback. You’ll then build a working model for users to react to, then integrate their feedback into an optimized final version of your app.
What are the 5 phases of the RAD model?
The 5 phases of rapid application development are business modeling, data modeling, process modeling, application generation, and testing and turnover.
What are the advantages and disadvantages of the RAD model?
Advantages of the rapid application development model include faster development and delivery, a more flexible end-product, and reduced risk. Some disadvantages are that it’s not ideal for smaller, technically risky projects, your system must be modular, and it requires a highly skilled team that’s willing to stay engaged throughout the project.
When would you use the rapid application development model?
Use the RAD model when you need to build an app in just two to three months, have the budget to afford highly skilled-talent and the technology they need, and are aligned on key business and user requirements.
