This document discusses the problem of complexity in businesses and provides strategies for reducing complexity. It defines a "Complexity Factor" metric to measure complexity based on products, markets, facilities, employees, and other factors. Case studies of Motorola show how complexity was reduced by standardizing parts and processes. The document provides a step-by-step approach to analyzing complexity sources like customers, suppliers, and products based on the 80/20 rule. It also outlines how to assign costs to complexity sources and control complexity over time.
