A researcher selects a research method according to whether the objective is to identify a certain type of information that is gathered before the onset of the study, or whether participants will be the source of that information. In addition to this, data may also be in the form of numerical information that is collected using scales of instruments documenting and reporting the participants’ voices.

An analytic process can be defined as one which there are agreed upon methods for generating alternative solutions to problems, and for assigning values to the 2 benefits and costs expected from each of the alternatives. The USAF has computational methods readily available for calculating benefits and costs ratios once these values are assigned. assigned. The critical point here being, given the structure, size, importance and power influence, there is a strategic need to continually be in sync with the DOD, the President, Congress, and fellow military personnel. The essence of the rational process is the belief that, "all good persons, given the same information, will come to the same conclusion".
