This document discusses using data to improve agile practices and outcomes. It argues that agile has lost the "data war" by not capturing and utilizing data from teams effectively. It suggests that data needs to be handled safely to avoid embarrassing people and destroying the utility of historical data. Better ways are needed to measure outcomes rather than just output, and to balance predictability with creativity. The document also discusses visualizing and managing dependencies, comparing performance across teams, and using the right metrics depending on a team's characteristics and challenges. The overarching message is that data needs to be used carefully and conversationally to drive the right actions and improve agile practices.
