Supplier to Zero V2 recognises achievement across three progressive performance levels:

• Level 1 – Baseline implementation 

• Level 2 – Advanced implementation 

• Level 3 – Best-practice implementation 

Performance is evaluated separately across the three Supplier to Zero focus areas:

• Input 

• Process 

• Output 

The final Supplier to Zero Performance Level is determined by the lowest level achieved across the three focus areas. For example, where a facility achieves Level 3 for Input, Level 2 for Process and Level 3 for Output, its overall Supplier to Zero Performance Level will be Level 2.
