The document discusses ways that agencies can evolve to better serve clients in today's digital landscape. It suggests that agencies need to break down silos between departments, encourage collaboration and ideas from anywhere. Hierarchies should be flattened with creative teams composed of diverse specialists rather than just writers and art directors. Processes also need updating - there should be no chemistry meetings, one briefing for all agencies, and ideas submitted simply on one sheet of paper rather than lengthy formal pitches. The structure should also evolve from separate groups to interconnected specialist teams collaborating on projects.
