Enterprise Architecture or Enterprise IT Architecture

[Latest News Headlines]

Adrian Campbell over at Inspiring Architects has what I think is a spot-on article discussing the differences between Enterprise Architecture and Enterprise IT Architecture. He focuses on the need of Business Architecture to ensure alignment to business objectives.

He starts his article with a slightly different thought around explicit and implicit architectures which could easily be another blog post. I agree that all organizations have an Enterprise Architecture. What varies over time is the type of technology used to implement the business. For example, when Sears started retailing back in the 1800s their DBMS of choice was a paper-based ledger. Now lots of whirling disks support the operation. Another variable is how much documentation is associated with an Enterprise Architecture. Are their formal specifications for the Enterprise or is it left to corporate folklore?

Nice work, Mr. Campbell
