EA First Week Journal

I'd love to start with our first case Ms. Rettig's The Trouble With Enterprise Software. I was kind of surprised that the current implementation of enterprise software in organizations is regarded hopeless in solving the problems exists in the legacy systems. But it is provoking indeed. At least one thing is shown to us that the software or IT ,though fancied by many executives of organizations,isn't a solution to all the requirements. Yet the trouble of it appears in certain stage of the overall development of IT of organizations. Such as the integration with and among current systems, the collection and presentation of the data and the demand for changes in business. I think all of these entail EA. 

In my point of view, EA is a tool or technique used to interpret the vision of organization into business processes, into technologies infrastructure. Due to various reasons and context, no one can simply throw all the old systems away and unite all the functional parts within the organization using a highly compressive system. But they can manage to partly implement the technology in core department in early stage and then form regulations for operations of their business processes and finally can reach a level in which standard data can be generated for use in relative compressive enterprise systems. The whole procedure can only be realized when there is proper EA.
