SAM: A Rapid Design and Development Model is a rapid software development model that was first proposed in 2010. It is based on the idea that rapid software development can be achieved through the use of standard agile methodology principles, such as sprints, daily standups, and retrospectives.

The SAM model is designed to help teams achieve a rapid turnaround time for software projects. It utilizes a modular approach to software development, which allows teams to easily identify and correct problems early in the development process.

The SAM model has been found to be effective in speeding up the development process. It has been used to develop software for a variety of platforms, including the web, mobile devices, and enterprise applications.

If you are looking to achieve a rapid turnaround time for your software projects, the SAM model may be a good way to go.
