Just enough enterprise architecture - supporting CIO decision making
Conclusion: Enterprise architecture should be viewed by CIOs as a fundamental toolset to provide sound, defensible, evidence-based decision making. CIOs who ignore or misunderstand enterprise architecture forego a powerful management device.
CIOs should understand and make use of the enterprise architecture techniques at their disposal; they must also recognise approaches to enterprise architecture that will not work. CIOs should set expectations with their enterprise architects for quick delivery of highly relevant outputs: days not years.
