We wish we could say that we have a "magic wand" that no other research agency has, but the truth is we use all the same research techniques and tabulation methods used widely in the business - in qualitative, quantitative and web surveys. We believe that it is in the ability to suggest optimized combinations of these options, including sample sizes, to our clients.
When you don't even know where to start digging, the best way is to perhaps go ask an expert to pick on his brain.

From qualitative surveys and interviews comes a fine-tuned "hypothesis" or yours to see if it really works. This is the stage when you need to conduct quantitative surveys - to get your results in percentages and other forms of objective information. It can be done through questionnaires or by increasing sample sizes of interviews if you so wish.
