1. A method for creating a minimally complex enterprise architecture, the method comprisingproviding a mathematical model for complexity byequating the number of possible states of a system with its complexity by equating states in a business process with decision points and decision branches, andequating states in an information technology system with variables and numbers of possible values,reducing the number of possible states of a system through mathematical partitioning, thereby diving the original system into subsets such that each element of the original system lives in one and only one subset, and using an equivalence relation to define the partitioning;

  • providing, on a computer, a model for enterprise architectural complexity that maps back to the mathematical model for complexity; and

    producing, with a process that is based on the model for enterprise architectural complexity, an enterprise architecture that is minimally complex as predicted by the model.
