Sawtooth

Sawtooth is used for measuring preferences on any combination of features. Conjoint (trade-off) analysis is one of the most widely-used quantitative methods in marketing research.

It is used to measure preferences for product features, to learn how changes to price affect demand for products or service, and to forecast the likely acceptance of a product if brought to market.

Sawtooth has two platforms:

• Lighthouse Studio: Create and analyze your surveys. Windows is required, but can be installed on Mac using Parallels. 
• Discover: Create and analyze your surveys in a web browser. This works for Mac.
