This document discusses managing innovation challenges and projects with high novelty, technology, complexity, or pace levels. It introduces the concept of "challenge management" instead of risk management for such innovative projects. Challenge management involves understanding the dimensions that define a project's uncertainty, assessing the specific challenges posed along each dimension based on a project's characteristics, and tailoring the project plan and management approach to address those challenges. Project plans need to be built around managing uncertainty through iterative cycles and later freezes of requirements and design. The document provides examples of how different levels of novelty, technology, complexity, or pace impact a project's challenges and risk areas.
