Making Enterprise Architecture More Than an IT Bureaucrat's Dream

摘要

An enterprise architecture (EA) seeks to provide a coordinated, disciplined, unified approach to systems implementation by defining a series of models at the organizational level. Best practice in defining an EA includes developing a communication plan, by which one hopes to communicate the substance and benefits of the EA throughout the organization, and a governance process that provides a controlled means of defining and evolving the EA over time. Viewed from the large-scale implementation trenches, EA governance efforts have fallen mostly into two categories: 1. A bureaucratic, political process that seeks to impose rule without reason upon development teams that would oftentimes deliver a much better product without such help 2. A software product salesman's dream, wherein the governing body drinks the vendor Kool-Aid and decides that "all systems will be written using Lotus Notes" or "our solution for all things is expensive ERP and HR products that refuse to talk to one another".
