A needs assessment is a type of research study that organizations conduct prior to designing a program, project, or other intervention. A needs assessment is done to obtain concrete evidence about the who, what, why, where, and when of a particular problem.
The needs assessment will provide you with knowledge:
That a problem or need does exist in a community
Potential causes of the problem (i.e., points of intervention)
This information will allow you to:
Prove to funders that this need exists and your intervention should be funded
Design an intervention that is highly likely to actually solve problems and attain your goals
