The Open Group is delighted to announce that Steve Nunn has formally taken over as President and CEO following Allen Brown stepping down from that role at the end of October 2015.
After conducting a process to choose Allen Brown’s successor earlier this year, The Open Group Governing Board selected Steve for the role. Steve has a distinguished career to date, previously the Chief Operating Officer (COO) of The Open Group and CEO of the Association of Enterprise Architects (AEA).
Steve joined The Open Group in 1993, spending the majority of his time as COO and General Counsel. Steve was also appointed CEO of the AEA from 2010 until 2015. He is a lawyer by training and has an L.L.B. (Honors) in Law with French and retains a current legal practicing certificate. Having spent most of his life in the UK, Steve has lived in the San Francisco Bay Area since 2007.
Outside of work, Steve enjoys spending time with his family, walking, playing golf, 80s music, and is a lifelong West Ham United fan.
“It’s an amazing time at The Open Group. Having recently attained over 500 memberships from organizations throughout the globe, The Open Group continues to move forward with tremendous momentum and opportunities to shape the standards that can help solve our members’ business problems. I am honored to be helping to lead that process,” Steve Nunn commented. “Allen has developed and grown the organization beyond all recognition in his time as CEO and I wish him the very best in his upcoming endeavors.”
Allen Brown, outgoing President and CEO of The Open Group added, “I ask that you join me in congratulating Steve Nunn as he steps into his new role as President and CEO. Having worked with Steve closely for many years building a great organization, I know he has all the capabilities to lead The Open Group to further growth and achievements.”
