  AI systems may have transformative and long-term effects on individuals and
society. To manage these impacts responsibly and direct the development of AI
systems toward optimal public benefit, considerations of AI ethics and
governance must be a first priority.
  In this workbook, we introduce and describe our PBG Framework, a multi-tiered
governance model that enables project teams to integrate ethical values and
practical principles into their innovation practices and to have clear
mechanisms for demonstrating and documenting this.
