A Digital Employee is an AI agent with the same four things you'd require before giving a contractor a badge and a login: its own identity, a defined scope, a defined authority boundary, and a managed lifecycle. Not a chatbot. Not a script. If it doesn't have its own identity and its own audit trail, you can't answer "who did this" six months from now.
A defined identity in the target system — never a shared or borrowed login. Whatever it does is attributable to it specifically.
An explicit list of the tasks it's permitted to attempt. Not "help with procurement" — the actual transactions, by type.
Thresholds within that scope: what it can complete alone, what needs sign-off, what dollar or quantity limits apply.
Provisioned, monitored, and revocable — same as any contractor's access. It can be suspended the moment something looks wrong.
For any non-trivial process, one agent doing everything is the wrong design. Split the work into narrow, single-purpose workers, coordinated by an orchestrator.
The same discipline you already apply to a human role — just compressed, and largely automatable. Monitoring runs continuously, not as a one-time checkpoint.
Most governance conversations only cover the first one. For an agent with real authority, the second matters just as much.
Both are architecturally valid. The right answer depends on your GRC posture and how much of this runs unattended — this is a call that should come from your GRC and SAP security team.
