This document provides a 4-step planning workbook for implementing generative AI (GenAI) in an enterprise. The 4 steps are: 1) establish a vision for GenAI by defining goals, benefits and success metrics; 2) remove organizational barriers to capturing value; 3) identify risks like regulatory issues, lack of skills, etc.; and 4) prioritize GenAI initiatives based on their value and feasibility. The workbook provides templates and examples for completing each step, such as setting key performance indicators for the vision, potential barriers and solutions, a risk assessment template, and a framework for prioritizing projects based on value and feasibility.
