This document introduces the Business Process Maturity Model, which is a multi-dimensional, non-linear model for assessing an organization's business process maturity. The model has two dimensions: 1) The "Five Levers of Change" which are the components that make up an organization, and 2) Five "States of Process Maturity" that represent stages an organization progresses through. The five states are: Siloed, Tactically Integrated, Process Driven, Optimized Enterprise, and Intelligent Operating Network. Moving from one state to the next is not linear and involves overcoming different hurdles for different parts of the organization.
