开发者_StackOverflow Improve this questionWe have a bunch of requirements documents and class diagrams, but are missing the document that brings it all together.
What is the correct term for a document that gives an overview of what a system does? Or what is the best way to present an overall picture of what is going on.
Something that starts with a high level picture of what’s going on, describes what the system provides, who it interacts with, and any dependencies, etc ?
Back in the 2167A and MIL-498 days we called it a Software Product Specification (or SPS).
If that isn't quite what you are looking for, try surfing around Simon's MIL-498 document website and see if one looks like what you need. You (probably) don't have to follow any of them exactly, but they make good templates.
What about a nice Domain model?
You said it yourself: System Overview.
Sounds like an architecture document to me. http://en.wikipedia.org/wiki/Software_architecture
