The document discusses the skills and knowledge needed for strategic information architecture (IA) careers. It defines strategic IA as designing high-value content and information experiences across entire organizations, products, or portfolios to meet business goals. This requires skills in user research, modeling, information design, analytics, business, leadership, and soft skills. Tactical IA focuses more narrowly on individual products or teams. The document provides examples of strategic IA tasks and derailment factors that limit effectiveness, such as being driven by rules or siloed thinking rather than strategic vision.
