Enterprise architecture (EA) can mean different things to different people, depending upon the role and responsibility of the individual within the organization and depending upon the context of the organization (either being a consultancy or an end user). To many it is a framework, while others view it as a collection of rules, or a methodology for defining and designing infrastructure services. However, the common aims are to improve alignment of the IT infrastructure with business goals and to attempt to bring stability to an ever-changing, chaotic, and complex situation.
