Phil Le-Brun:

Rather than pretending you can craft the perfect organisation chart and operating model, I advocate starting with principles and tenets to guide your organisation. The former method is an overly logical and static approach to human issues, as I described in my first post on untangling your organisational hairball. Principles have (I hope) shifted from outdated concepts, such as spans of control, in search of elusive efficiencies to those better suited for an era where complexity, speed, and innovation define organisations. Previous blog posts give in-depth examples of principles and decision-making tenets. But remember, the most beautifully crafted principles in the world mean nothing unless a comprehensive understanding of them cascades throughout the organisation.
