Roger Evernden (born ca. 1954) is a British enterprise architect, musician, composer, writer and speaker.
As an enterprise architect he is a consultant at the Cutter Consortium, known as author of the Information FrameWork, an enterprise architecture framework presented in 1996 as more generic alternative to the Zachman Framework.
As a musician and composer  he is best known for his new-age music solo piano albums - "Improvation" released in 2014, "The Journey We All Make" in 2016,  "The Innocence of Spring" in 2018,  and "Nocturnes" (2019).
Evernden started his career as history teacher in London in 1977. In 1980 he started working in IT as analyst and programmer, and worked his way up from consultant and application developer to enterprise architect working for companies as Legal & General, IBM, Westpac Banking Corporation, and smaller companies. From 2007 to 2011 he was Enterprise Domain Architect and later Enterprise Architect at Lloyds Bank. Since 2011 he is Senior Consultant with Cutter Consortium's Business & Enterprise Architecture practice,
In the late 1980s Evernden developed Information FrameWork (IFW) to describe an enterprise architect initiative at Westpac. This was later described in an IBM Systems Journal article, published in 1996. The Westpac project - known internally as CS90, or Core Systems for the 1990s - was a prototype for using enterprise architecture to create adaptive organizations or adaptive systems. The Westpac experience was described by Stephan H. Haeckel - an American management theorist and former director of Strategic Studies at IBM's Advanced Business Institute - who developed the idea of the sense-and-respond organization as an adaptive enterprise.
The Information FrameWork (IFW) was presented in 1996 as framework for Information management, and more generic alternative to the Zachman Framework. Evernden (1996) explained:
In his 1996 paper Evernden also showed "how the structure of IFW has been populated by industry-wide models and supported by a distinctive methodology. A detailed discussion of each of the six dimensions of the IFW architecture is presented."
Evernden is co-author, with Elaine Evernden, of Information First: Integrating Knowledge and Information Architecture for Business Advantage, which was first published in 2003, expanding the concepts of Information FrameWork (IFW). Information First outlines an approach to enterprise architecture that uses eight factors common to all enterprise architecture frameworks that can be combined to create architectural tools for managing enterprise and business transformation. A second edition was published in 2015 with the title: Enterprise Architecture - the Eight Fundamental Factors.
In 2008, at the height of the financial crisis of 2007-2008, he spoke about how enterprise architecture could be used to weather unpredictable events. In 2011 he described the architectural approach to create a single integrated IT platform from two heritage banking systems following the Lloyds TSB acquisition of HBOS to form Lloyds Banking Group January 2009.
In 2017 he presented a case study at Vesta Corporation describing a combination of online training and webinars in a nine-month program to build the capabilities and confidence of their enterprise architecture team.
In a keynote presentation for the National Conference on Advances in Enterprise Architecture (NCAEA 2017) he described changes required by architecture frameworks in response to an increasingly connected, digital world. He said: "Although our discipline will probably continue to be known as "enterprise" architecture, increasingly it will cover the architecture of any human-designed system - which includes all social, political, economic, environmental, and cultural organisms - in addition to the domains we currently expect to find in "enterprise" architecture. Enterprises, and governments, will need to re-think governance of their EA." 
During the 70s & 80s he played and wrote songs with bands, including Capital Chaps, and Watch My Lips.
The solo piano albums Improvation (2014), The Journey We All Make (2016), The Innocence of Spring (2018), and Nocturnes (2019) have a unique melodic blend of classical, new age, jazz, and improvisation.
