Start with one process
Pick one high-volume, repeatable process that causes the most grief. In financial services that might be KYC document processing, trade reconciliation, credit decision pre-screening or treasury reporting. These are text-heavy or rule-heavy, and they sit close enough to core systems to be useful first pilots.
Map the current process on one page. List inputs, outputs, decision points, systems and handoffs. Use timestamps or a simple stopwatch study to measure how long each step takes.
- Capture error types and rates. Note problems such as misclassified documents or reconciliation mismatches.
- Mark regulatory touchpoints. Record where audit trails, consent records or retention rules apply.
- Score each process on volume, repeatability and risk. Start with high-volume, low-risk work first.
- Look for structured outputs. AI is more useful when it produces machine-readable results that feed downstream systems.
- Leave high-risk judgement tasks for later. Use human review where that judgement still matters.
Match the task to the tool. Use optical character recognition and document classifiers for scanned forms; use supervised models for numeric scoring; use large language models for extraction and summarisation where human review is acceptable.
Check integration options before you go too far down the road. Prefer vendors with REST APIs, webhooks and connector libraries for your core ledger or case-management system.
Data residency and explainability need checking as well. You need to be able to show why a decision happened, and where the training data came from.
Keep the pilot small
Create a tight pilot group: one process owner, one compliance reviewer, one data engineer, one ML engineer and one product owner. Keep the group small.
Give people clear jobs. Name who signs off on outputs, who handles incidents and who maintains the pipeline.
Bring the compliance reviewer in from day one. They should have a real say on any data sharing, not just a sign-off at the end because everyone else has already built it.
- Log every model decision. Record inputs, model version, timestamp and the human reviewer ID where applicable.
- Apply data minimisation and masking. Remove or tokenise personal data not required for the model.
- Set retention and audit windows. Keep raw inputs long enough for audits, then delete them according to policy.
- Add a simple challenge process. Use a second reviewer or a rule-based check to flag odd outputs for manual review.
Implement it like software
Treat implementation like software delivery rather than research. Define acceptance criteria, run controlled tests and keep rollback options available.
- Define acceptance measures. Examples: extraction accuracy above X for key fields, false positive rate below Y for fraud flags, or mean time to resolution reduced by Z minutes. Use the measures the process owner cares about.
- Create a deployment checklist. Include API keys, model version, schema contracts, RBAC settings and log paths.
- Start with a shadow run. Send AI outputs alongside the existing process for a defined period and compare them with human results before you switch anything over.
Train operational staff on output interpretation, not model internals. Give them runbooks: how to read the confidence score, what to do when confidence is low, and how to raise an incident.
Run hands-on sessions with real cases and edge cases. Include the sort of failures that actually happen, not just the neat examples.
Appoint an AI custodian. That is the named person who owns shift-level oversight, triage and retraining requests.
- Watch for drift. Monitor input feature distributions and prediction patterns, and alert when they move outside a fixed window.
- Track key measures daily. Use dashboard tiles for accuracy, latency, confidence distribution and manual override rate.
- Sample outputs regularly. Do a small daily audit of random outputs and log any corrections.
- Build a lightweight feedback loop. Let reviewers flag outputs with a single click and record reason codes.
- Turn flags into labelled data and use them for retraining.
- Keep retrain cadence predictable. For many pilots, fortnightly or monthly works until the thing settles down.
Scale carefully
Standardise contracts and connectors. Use a common schema for AI outputs and a single API gateway so you do not end up with a pile of bespoke work.
Add a model registry. Record model metadata, training data snapshot, performance baseline and deployment history.
Use infrastructure-as-code. Keep environment parity from test to production and automate rollbacks.
Watch cost and latency. Track inference cost per transaction and set budgets. For high-volume flows, batch scoring or on-prem inference may be the better fit.
- Set a rollback threshold. If manual override rate or error rate exceeds a preset value, revert to human-only processing.
- Keep an incident playbook. List the steps to quarantine bad inputs, revert model versions and notify compliance.
- Run periodic independent validation. Use a separate reviewer or external assessor to check performance and policy adherence.
Two examples
For KYC document classification, run a three-week shadow period, then a two-week parallel period where the AI output is used to pre-fill forms that a human signs off. Measure time saved per KYC by comparing median processing times.
For trade reconciliation, start with rule-based matching plus an ML classifier for exceptions. Move to automated matching for high-confidence cases and keep human review for low-confidence matches.
Start small, measure what matters and keep compliance visible. Use shadow runs and clear rollback thresholds to avoid surprises. Give one person custody of the pipeline and record every decision.
