Which statuses are part of the 4 Eyes Principle in Tosca Best Practices?

• A. In-Work, Ready for Approval, Approved/Completed.
• B. Draft, In Review, Approved, Rejected
• C. Open, In Progress, Completed
• D. Pending, Approved, Archived

Answer: (A)

The 4 Eyes principle in Tosca Best Practices uses a three-step lifecycle that enforces dual control: development, review, and final approval. In-Work means the artifact is being actively created or edited. When work is complete and ready for another person to check, it moves to Ready for Approval, indicating it’s awaiting a second pair of eyes. Once a reviewer signs off, it becomes Approved/Completed, showing the change has passed dual validation and is finalized. This progression ensures that no single person both creates and approves the change, which is the essence of the 4 Eyes approach.

Other option sets use terms that don’t align with Tosca’s defined gating states and can include outcomes or stages not part of the formal review flow, such as Open or In Progress without a clear handoff, or include states like Rejected or Archived that fall outside the intended three-step ready-for-approval lifecycle.
