Sometimes, the development of a simulation to model our solution's behavior can take more time and money than a trial-and-error experiment.
While there are several things that can make trial-and-error methods undesirable, we should keep two common sense axioms in mind.
Do not just assume that analyses, models, and simulations are as good as or better than trial-and-error.
For example, additional studies testing the effectiveness of stimulus-modification procedures to response-prompting prOcedures probably are not needed, nor are additional studies comparing stimulus modification or response prompting strategies to error correction and trial-and-error.
The data are fairly consistent that the stimulus-modification procedures will be more efficient than response-prompting strategies, and response-prompting-strategies will be more efficient than error-correction and trial-and-error procedures.
