VEST
VEST measures the potential penetration or usage levels for new or emerging product categories. If you have a truly unique product or service where no category data or norms exist, traditional purchase-intent measures such as Top-Box will dramatically overstate the potential of the idea. VEST utilizes each respondent's past purchase behavior in a wide range of product categories to determine his likelihood of following through on his survey "wish list." Therefore, the resulting predictions correlate almost perfectly with market behavior.
For New Products
  • determining the potential market size for the product
  • impact of price on penetration potential
  • impact of features/benefits on penetration potential
  • defining target audience for product
For New Services
  • comparing the potential of alternative service offerings
  • impact of price on subscription potential and usage frequency
  • impact of features/benefits on subscription potential and usage frequency
  • defining target audience for new service
