The document discusses the idea of an "Agile Change Mashup" where change practitioners are asked to work on agile programs and projects, and agile coaches are asked to effect large-scale change. It proposes combining the skills of agile coaches, who focus on team-level work, and change practitioners, who focus on the organization level. The mashup would focus on both the team and organization, applying systems and complexity thinking with a toolbox of agile methodologies and communication techniques. The document provides examples of how change practitioners and agile coaches can support each other and debunk myths about agile approaches. It encourages readers to try creating their own mashups.
