The document discusses the role of enterprise architecture (EA) in agile IT environments. It notes that EA has two main purposes: to support business and IT decision-making through information repositories and models, and to provide guidance to IT to develop and deploy assets that support the business through eliminating redundancy and promoting alignment. The document also states that most IT shops are dysfunctional, spending most of their budgets on maintenance instead of innovation and unable to keep up with business needs. It argues that a new service-oriented approach to application modernization is needed to bring about the modularization, reuse, and rapid development capabilities required for IT agility.

2. EA Has 2 Fundamental Purposes
1. Support decision-making by the business (mission)
and IT leadership
Repository of information about enterprise components and their
interrelationships
Models that indicate the future direction of the enterprise
2. Provide guidance to IT to develop & deploy assets that
support the business
Eliminate (reduce) redundancy, inconsistency, inefficiency
Promote alignment, sharing (reuse) and interoperability

3. Why Do We Need a New IT Approach?
Primary meta-driver in large organizations is the need to
leverage change
Business and IT must be closely linked to achieve this
EA plays a major role in enabling this
Most IT shops are dysfunctional
Multiple, redundant applications – inflexible, inconsistent, costly
Majority of IT budget spent on maintenance (70 - 80%)
Unable to keep up with the business
Impact
Companies lose 6% of their growth in sales per annum because IT
does not meet their business requirements (A.T. Kearney 2007)
Business as Usual won’t get us there
Need to rethink EA and IT as a collection of service-providing assets
