State of EA globally

“More than 25% of EA groups have been disbanded or demoted in the past 18 months due to complex demands to which EA has struggled to respond. EA groups need to fundamentally reevaluate their value proposition within the enterprise or risk a diminished EA future state”

Business Value Driven

Building High Performance Group IT

Change in EA required

• Focus the skills and competencies (such as creating guidance, road maps, principles, standards and best practices) of your experienced enterprise architects, first and foremost, on delivering actionable and diagnostic deliverables that address disruptive trends and deliver business outcomes.

• Proactively look for opportunities to hire and augment your EA teams with people who understand the major industry disruptions (nexus, digital business, regulatory, industry changes) that can impact the business.

• Budget time, energy and money in 2014 to appropriately invest in information and business architecture resources, skills, communication and tools, as well as in solution and technology architecture.
