The document discusses the importance of assessing an organization's readiness for growth. It identifies three phases of growth an organization can be in: growing, stagnating, or declining. It emphasizes that while individual departments may have efficient processes, the greatest potentials for improvement often lie in the interfaces between departments. Properly clarifying interfaces through agreements on expectations and responsibilities is essential for coordinating efforts across an organization and enabling sustainable growth. The document provides examples of how failures to adequately address interfaces can undermine otherwise well-planned initiatives and result in missed deadlines, quality issues, and other problems.
