Feedback, questionnaires, and surveys for any product in the planning phase reveals statistical numbers leaders can analyze. In order for any quantitative research method to work, one must first establish the baseline of what will be analyzed.
For example, will a certain widget sell as is? To find out, quantitative methods pool participants in various ways and match actual and factual numbers to the questions asked. Here, questions on market share, market demographics, and customer satisfaction can be achieved and those results used to improve the widget or change the widget (or elements of the widget) entirely.

Qualitative First

A new child’s phenomenon hit the market not too long ago—Pillow Pets by San Diego creator, Jennifer Telfer. Her idea incorporated a stuffed animal pet with Velcro which opened up into a sleeping pillow. Using the Pillow Pet example, we must first look at the qualitative method first

Most likely in developing her first Pillow Pets, Ms. Telfer looked at gender-specific designs. After all, girls may not like giraffes as much as boys or boys may want to skip the panda, etc. Let’s say this phenomenon had initial problems right off the bat—no sales.
Qualitative research always comes first, so in our scenario to determine the problems with low sales of the Pillow Pet qualitative research shows the reason for the low sales. For example, perhaps a focus group of children were gathered with a variety of designs to determine favorites and the not so favorites.

Using The Method

In keeping with our Pillow Pet example, from the focus group, perhaps the following was found:
No child of either gender liked the way the snake pillow felt when unfolded and found it uncomfortable.
Females thought the snake looked mean.
The polar bear was not white and black in color.
From here, the quantitative research method can begin by using various methods to determine why faults occurred and ways to fix them.
Qualitative research shows what is wrong, where quantitative methods reveal ways to improve products based on end-user input; or numerical data that can be analyzed.
Once qualitative researched showed no child wanted the polar bear or snake pillow pet, each were specifically questioned on why to determine the exact reasons. Once these reasons are discovered, quantitative research can begin.
