technology to effectively innovate their business models. Based on client interactions, 2 we nd that, in the majority, organizations that segment business architecture as an independent discipline from EA are really supporting business architecture and "IT architecture" as stovepipes — regardless of what the function is being called. That is because if business architecture, including business model, people, processes and investments, is not part of or extracted from EA, there is no context of or tie to the business vision that provides the business need. Without business architecture, there is a signi cant probability that the organization is left only with the "IT architecture" view into information, technology and solutions. In doing so, organizations are putting in place a structure that does not enable or encourage the development of an integrated enterprise (business and IT) future-state vision, and execution plans and road maps. For organizations to strategically view and evolve their businesses overall, including integrating business and IT, to deliver business outcomes, EA must include an understanding of business, information, solutions and technology. Highly Mature Organizations Support Business Architecture as Part of EA In a recent survey of Gartner clients and nonclients, 11 we found that the majority of organizations (67%) are supporting both EA and business architecture. Of those who responded that they support EA and business architecture (n = 121), we nd that: 24% responded that they support EA and business architecture as independent disciplines 41% responded that they support EA and business architecture as related but independent disciplines 35% responded that they support EA and business architecture as one integrated discipline Page 6 of 11 Gartner, Inc. | G00269233

On the other hand, a noticeably higher percentage of respondents, at a lower level of maturity (Level 3), supported EA and business architecture as related but independent disciplines. Finally, a higher percentage of respondents at an even lower level of maturity (Level 2) supported EA and business architecture as independent and related but independent disciplines. Figure 2. Level of Integration of EA and Business Architecture by Maturity Source: Gartner (October 2014) While these responses are based on the respondents' self-identi ed maturity versus scores from taking Gartner's ITScore assessment, they give us a compelling illustration of how organizations support business architecture relative to their overall perception of their maturity.
