Purpose of the Concept Test: Determine which of three alternative concepts should be pursued, as well as determine any potential improvements on the current concepts. 2. Survey Population: Seventeen college students and three non-college students were interviewed. 3. Choose a Survey Format: Face-to-face interaction was used as a survey format, with a written survey that the interviewee completed. 4. Communicate the Concept: Both a sketch and written description were used to communicate the concept to interviewees. Verbal descriptions of the product were not used, to prevent inconsistencies that could lead to bias. 5. Measure Customer Response: The test attempted to measure purchase intent, and utilized the five-response categories of the purchase-intent scale for each concept. Product improvement suggestions were communicated verbally. 6. Interpret the Results: The purpose of the test was to compare the three concepts, and decide which one to pursue for further development. Through the results, it was determined that the Tooth Pen was the concept best received, with a probability of purchase of 9%. As referenced from U&E, the probability of purchase was calculated as: Probability = 0.2*(Number of “probably will purchase”/total)+ 0.4*(Number of “definitely will purchase”/total) The results of the survey are as follows: Concept 1: Concept 2: Toothpaste Base Tooth Pen Concept 3: Swiss Army Dental Contraption Selected Concept: Tooth Pen: The toothbrush has toothpaste inside that is squeezed up through the bristles when the bottom is “clicked” (like a pen).
