Fact-finding is an important step in the development process that includes techniques such as interviews, document review, observation, surveys and questionnaires, sampling, and research. The Zachman Framework for Enterprise Architecture is a model that utilizes traditional fact-finding questions in a systems development context. Use the book and your own research to explore the various fact-finding techniques to determine more about each technique as well as other techniques that are available. Knowing that time and budgets always present constraints, discuss which techniques you think are best to use and why.

Rapid action development(RAD): It impels the information system development and generates the functioning development.contains the four phase cycles whih analogies the traditional SLDC steps.It massively depends on the prototyping and user participation.The RAD team utilizes the CASE tools to construct the protypes and generate a contiguous flow of documentation.An effective RAD should contain IT resources,skills amnd management assistance.

I think RAD is best to utilize due to the above reasons in RAD.
