The document provides an overview of how project-based work is impacting client-agency relationships. It discusses how clients are working with multiple agencies for specific needs and projects rather than relying on single "agency of record" relationships. Agencies are encouraged to focus on solving clients' business problems better, delivering work more efficiently through approaches like Agile, and pricing their work based on value rather than hours. The document suggests agencies can thrive in this environment by leveraging their expertise in specific categories or functions, minimizing interruptions to optimize workflow, and positioning themselves as experts that clients hire for their knowledge rather than just their services.
