Diane Bartoli discusses how analytics can drive effective product development. She outlines several tools that can be used including ethnographic research, workflow mapping, and quantitative surveys to understand user needs and pain points.

While there is a lot of available data, asking the right questions is key. Analytics should be integrated throughout the product development process from alpha to beta testing to ensure products truly meet user needs.
