We will explore for your system-of-interest what its main functions are and its key performance parameters (KPP).
As an architect, you should be able to explain how your key functions and KPPs serve your supersystem,
as well as provide directions to the subsystems to what functionality and performance they need to deliver to your system.
Combining this information with project information forms a project overview.
The single sheet overview is a powerful means to keep focus in projects.
