Does ZBB mean every budget starts at literally zero every year?

Beginner

Answer

The 'zero base' means no spending is assumed to continue automatically—each activity must be justified—not that the organization plans to spend nothing. Essential and value-adding activities are re-justified and funded; the point is that continuation is a decision, not a default.
Real-world example Core services are re-justified and funded under ZBB; nothing is simply assumed to carry over.
