The Joint Technical Architecture is our encyclopedia of standards. We also follow the Defense Information Infrastructure's Common Operating Environment as defined by DISA and endorsed by the Office of the Assistant Secretary of Defense for Command, Control, Communications and Intelligence. We accept the JTA and DII COE as the gospel, and we do not endorse technical standards that are not captured within those two constructs. I have a division here whose primary responsibility is systems architecture work. Creating systems architectures, at least to the level of detail where we show how things fit together, is an important contribution that we can make.
Systems architectures are the blueprints, and in every theater the blueprint is a little different.
There's no way that DOD can have a system architecture to serve as a single solution. We have a pretty standard environment. We use a combination of Microsoft Windows NT, Exchange and Outlook. Our headquarters now has centralized acquisition. We are the ones who buy the machines and the software for everybody to use, and we maintain configuration control.
