Borrower Business Viability Assessment refers to evaluation of borrower business viability as part of credit underwriting or portfolio monitoring. It helps the lender identify risk, repayment comfort, policy compliance, and required mitigants. Define the scoring basis, source data, frequency, and approval impact before using it. In MSME credit, it converts borrower behaviour, financial signals, compliance gaps or business dependencies into a clearer risk view for approval and monitoring. For example, stable orders, diversified customers, manageable debt and experienced promoters support viability, while repeated losses or weak controls reduce comfort. It matters because it helps the lender decide whether to proceed, add conditions, seek mitigants, reduce exposure or monitor the account more closely. The common mistake is to treat the indicator as a final decision by itself; it should be supported by evidence, trend analysis and credit judgement.
