Published sources behind the S-SME numbers. Every score in the S-SME Toolkit is anchored to a source: development-bank guidance, energy-access studies, and SME resilience research, with the exact reference recorded.
Keeping the evidence public matters for a simple reason: when a bank, investor or regulator reviews an S-SME assessment, the underlying claim can be checked rather than taken on trust. It is the same principle behind the OMSF grading of open models.
