From strategy to execution

Having an Enterprise Architecture (EA) is critical to any organization as it provides the necessary linkage from business strategies through execution – with many steps in between.  This traceability provides critical details about cause and affect – if I change something in my IT layer, what processes, people and strategies does it affect?  And the other way around: from changed business strategies into the impact on IT applications and technology portfolio. Questions like these (and many more) help a business understand the impact of change before it happens.
