Define the vocabulary and ownership
Inventory the reasons emitted by existing systems and identify ambiguous, overlapping or unused codes. Give each code a definition, source logic, applicable products and accountable owner. Separate operational processing errors from reasons associated with a credit decision.
Map outputs to real decision drivers
Trace each reason to the inputs, rules or model explanation that produced it. Define precedence when several conditions apply and validate handling of missing values and overrides. Avoid translating a technical feature into customer-facing wording without review by the institution's authorized specialists.
Control changes and monitor use
Version the mapping and review changes alongside model or policy releases. Monitor unmapped outputs, unexpected shifts and inconsistent use by channel. Cicrim can support the code inventory, mapping design and validation scenarios needed for a governed implementation.
Plan the next working session
Bring the current process, the accountable business and control owners, and the questions your team needs to resolve. Cicrim can help define a focused scope, expected working outputs and acceptance criteria before delivery begins.
