Is Lead RM identifies the relationship manager who has primary responsibility for coordinating the borrower relationship or credit proposal. In MSME lending, multiple teams may be involved, including sales, credit, operations, legal, valuation, and monitoring. A clearly tagged lead RM helps ensure that document collection, customer communication, query resolution, sanction conditions, and post-approval follow-up are owned by one person. For example, if financial statements or collateral documents are pending, the lead RM is usually responsible for coordinating with the borrower. This field matters for workflow accountability and audit trail, not for credit strength. The caution is to keep the tag current when cases move between branches, teams, or relationship managers.
