We had a hypothesis that our listeners might be interested in hearing an expert on digital optimization. In this episode we test that hypothesis. Listen and learn as Kelly Wortham from EY runs circles around the lads, and brings them to an understanding of what digital testing means in 2015. In an hour so optimized it only takes 45 minutes, it's 2015's penultimate episode of the Digital Analytics Power hour.

People, places, and things mentioned in this episode include:

• Taguchi vs. Full Factorial test design
• kelly dot wortham at ey dot com (to get added to Kelly's twice-monthly testing teleconference)
