Technology architecture - Document
SAD
(Solution Architecture Document)
A document showing how a proposed solution fits together, including its main parts and connections
What's it for?
Shows how the main systems in a proposed solution should fit together so teams have a shared design to work from.
For example…
The payroll migration SAD shows which HR system remains master for employee data, how nightly files reach finance, and where single sign-on applies
A SAD for a new payments service shows the applications, databases, interfaces, security boundaries and main data flows that make up the proposed solution
Think of it like…
Wiring diagram for a house extension — not every screw, but enough to see how power, heating, and network connect
