This document discusses the concept of "hull speed" as an analogy for the limits of incremental change in an organization. It explains that boats have a maximum speed based on hull design called hull speed, beyond which additional power cannot increase speed. Similarly, organizations can reach a point where incremental changes no longer improve results and a restructuring may be needed, just as modifying a boat's hull is required to exceed its hull speed. The document provides examples of changes that initially improve performance but eventually reach diminishing returns. It prompts the reader to consider if they have observed this phenomenon and what additional changes could provide more benefit without major restructuring.
