Design Document

I am sure as project managers we have had to review the design documentation of the architecture team. I have had several such design documents handed over to me for perusal each with a different layout, content , format etc Making me wonder arent all these stuff supposed to contain the system architecture in detail then why this difference?

Did you review any design documents? What do you look for? What do you expect it to contain? Do you expect any other artefacts other than just a document. Let me know.
