Gartner’s 2010 Hype Cycle for enterprise architecture (EA) reveals that two generations of EA, one currently focusing on IT-oriented practices and the other rising to focus on integrating and engaging with the business. The Hype Cycle also shows how EA will further evolve and how enterprise architects will utilise and govern EA within the business in the next 10 years.
Gartner defines EA as the process of translating business vision and strategy into effective organisational change by creating, communicating and improving the key requirements, principles and models that describe the organisation’s future state and enable its evolution.
“The artificial walls between business and IT are crashing down, and EA is the bridge to integrate business and IT,” said Philip Allega, Research Vice President, Gartner. “EA’s original promise was its ability to provide future safe guidance given the desires and vision of an organisation’s senior leadership team. As IT roles shift away from technology management to enterprise management, EA is suited to bring clarity to these blurred boundaries, and, by 2015, increased adoption of EA processes and uses by business will further IT’s alignment with the organisation’s culture, future-state vision and delivery of business value outcomes.”
Early-generation EA, situated on the right side of the Hype Cycle, is marked by long-standing and well-practiced approaches such as enterprise technology architecture (ETA) and architecture assurance that have been supported by traditional and federated approaches to EA. While these practices help to direct tactical IT operations, they are often supported without a business future-state vision and, as such, limit the ability for organisations to achieve and demonstrate significant business value.
“Overall, EA slipped into the Trough of Disillusionment, along with EA tools, because EA practitioners couldn’t or wouldn’t push EA efforts to become integrated with the business, drawing an invisible wall between the business and IT,” said Allega.
As EA practitioners have become more business-focused and organisations have become more hyperconnected, new approaches of managed diversity and middle-out have emerged on the Trigger slope, forming the latest generation of EA. These disciplines are employed by end-users to try to integrate and engage with the business as a partner. One of the emerging disciplines includes a middle-out EA approach, which according to Gartner will have a transformational impact on business in the next two to five years.
“The middle-out approach enables the creation of an adaptable architecture that can help manage rapid change and enable innovation by focusing on coordination through interfaces, rather than on control through top-down standards,” said Allega.
Gartner found that 73 percent of clients aspired to support “mature enterprise architecture” during the next three to five years, demonstrating that business strategy will be pervasively understood and supported within EA and across business and IT. “We predict that by 2015, the marketplace of EA practitioners will find a landscape very different from today’s environment,” said Betsy Burton, Research Vice President and Distinguished Analyst, Gartner.
“To prepare for 2015, EA practitioners need to ensure that EA practices are driven by a clear business vision and defined business context, and that their EA program has stabilised the practices and disciplines that are less than two years to mainstream adoption.”
