There are numerous software development models suited for developing different types of systems or applications, based on your business specific needs. Picking up the right model is extremely important for delivering the expected results within the defined time limits, inside the approved budget. To select the right approach to develop your software, you need to understand the differences between the standard software development models out there.

In this post, we explain two of the widely used software development models: Rapid Application Development and Lean methodology, the development process followed by each and how combining both the methods could benefit your business.

Rapid Application Development (RAD)

Also known as Rapid Application Building (RAB), it is one of the adaptive software development approaches which evolved to challenge the traditional Waterfall development practices. RAD places less emphasis on planning and more on the adaptive process. It focuses on rapid prototyping and user feedback over stringent and costly planning and requirements recording.

While Rapid Application Development de-emphasizes rigid planning, like any other software development methodology, it involves some specific steps which can be broadly classified into the following four phases:
