How to change credit policy rules without waiting months for IT

To change credit policy rules without waiting months for IT, take the rules out of your core banking or origination code and put them in a no-code decision engine your risk team controls. IT connects the engine to your data and channels once. After that, the risk team edits rules in a visual editor, tests each change on past decisions, and deploys a new version after the bank's normal sign-off. Konan, the credit decisioning platform from Synapse Analytics, is built for exactly this.

Why rule changes take months

In many banks, credit rules are written into the loan origination or core banking system. So a change of one cut-off becomes an IT project: a written spec, development, testing and a slot in the release calendar. Meanwhile the risk team, which knows what needs to change, can only wait. The fix is to separate who decides the policy from who runs the systems.

5 steps

Move the policy out of code. Put rules, scorecards and models in a decision engine that sits between your channels and your core systems. Each application goes to the engine, and the engine returns the decision.
Give the risk team a visual editor. Exclusion rules, scorecards, custom scripts and AI models should all be editable without code. In Konan this is the Digital Policy Builder.
Test every change on past decisions. Before go-live, run the new policy against historical applications. Compare approval rates and expected bad rates with the current policy.
Version and approve. Every change becomes a new policy version. Keep your four-eyes or committee approval, and keep a log of every decision with the rules and scores behind it for audit.
Deploy and watch it live. Track approvals, bad rates and volumes as they happen, get alerts when a segment drifts, and adjust thresholds based on what you see. See real-time portfolio monitoring.

What IT still owns

IT doesn't disappear. It sets up the platform where your regulator requires (on-premise, private, public or sovereign cloud, or air-gapped), connects data sources such as credit bureaus and open banking, and runs security. The difference is that this happens once, not for every rule change.

How Konan does it

Risk teams build, test, version and change credit policies themselves, in a no-code editor.
Simulations run on past decisions, so the impact is known before go-live.
Bureau, open banking, device, telecom and utility data can feed the same policy.
Every decision is logged and explainable.
Konan runs inside your perimeter, and its models run in your infrastructure.

Frequently asked questions

Why do credit policy changes take so long in banks?

Usually because the rules are coded into the origination or core banking system. Each change then needs a spec, development, testing and a release slot, even for a single cut-off.

Can a risk team change credit rules without IT?

Yes, once the rules live in a no-code decision engine. In Konan, risk teams build and edit policies in a visual editor and test them on past decisions before going live.

How do you test a credit policy change before going live?

Run the new policy against historical applications and compare approval and bad rates with the current one. Konan runs these simulations without affecting live decisions.

Do no-code policy changes still pass audit and approval?

They should. In Konan every policy change is versioned and every decision is logged with the rules and scores behind it. The bank keeps its own approval steps.

What does IT still do with a no-code decision engine?

IT deploys the platform, connects data sources such as credit bureaus and open banking, and owns security. It does this once, not for every rule change.
